If you were to solve the following system by substitution, what would be the best variable to folve for and from what equation?

3x+6y=9
2x-10y=13

A) y in the first equation
B) y in the second equation
C) x in the second equation
D) x in the first equation

Answers

Answer 1

Answer:

D

Step-by-step explanation:

It's easiest to divide everything by 3.

Answer 2

The best variable to solve for is x in the first equation.

How to solve the equations 3x+6y=9 and 2x-10y=13 by substitution?

Let 3x+6y=9 be equation (1)

and 2x-10y=13 be equation (2)

2x-10y=13

10y = 2x - 13

y =[tex]\frac{2x - 13}{10}[/tex]  

substitute the value of y in equation (1)

3x+6y=9

3x + [tex]6(\frac{2x - 13}{10})[/tex] = 9

3x + [tex]3(\frac{2x - 13}{5})[/tex] = 9

[tex]\frac{15x + 6x - 39}{5}[/tex] = 9

21x - 39 = 45

21x = 84

x = [tex]\frac{84}{21}[/tex]

x = 4

Therefore, option D) x in the first equation is the correct answer

Write the equation of a line that includes the point (22, 12) and
has a slope of 4 in standard form.
@ -4x + y = -76
6 4x + y = 100
@ -4x+y=-100
@ 4x + y = 76

Answers

Let's start with y = 4x + b (since 4 is the slope);

We need to find what number should be put instead of b;

Then, let's see what needs to be done;

Plug in the y and x values from the coordinate (22,12) into y=4x+b;

12 = 4(22) + b

Solve;

12 = 88 + b

12 - 88 = b

b = -76

Remember the equation y = 4x + b? Put the -76 instead of b:

y = 4x + -76

or: y = 4x - 76

That is the equation.

To make it standard form, put x and y both in the left side, with x first then y:

-4x + y = -76

^^Answer!

Final answer:

The equation of the line which passes through the point (22, 12) with a slope of 4, when written in standard form, is -4x + y = -76.

Explanation:

To write the equation of a line that includes the point (22, 12) and has a slope of 4 in standard form, we begin with the point-slope form of a line equation, which is y - y1 = m(x - x1). Substituting the given point and slope values, we have y - 12 = 4(x - 22).

Next, we simplify and convert this equation to standard form Ax + By = C. Standard form requires that x and y terms are on the left side and the constant is on the right:

y - 12 = 4x - 88
Add 12 to both sides:
y = 4x - 76
Subtract 4x from both sides:
-4x + y = -76

This is now in standard form and matches one of the given choices.

Step-by-step explanation:

Please try to do a better job of formatting your next question.  Thanks.

110 in       1 ft

-------- * --------- = 9 1/6 ft  or  9 ft 2 in

   1          12 in

110 in = 9 ft  2 in.

To convert 110 inches to feet and inches, we need to know the conversion factor that:

[tex]1\ foot = 12\ inches[/tex]

So, first, divide the total inches by 12 to get the number of feet:

[tex]\frac{110\ inches}{12\ inches/foot} = 9\ feet[/tex] with a remainder.

The remainder represents the inches that do not make up a full foot. The remainder can be calculated as follows:

[tex]110\ inches - (9\ feet \times 12\ inches/foot) = 110\ inches - 108\ inches = 2\ inches[/tex].

So, 110 inches is equal to 9 feet and 2 inches.

Therefore, 110 inches = 9 feet 2 inches.

Diego wants to survey a sample of students at his school to learn about the percentage of students who are satisfied with the food in the cafeteria. He decides to go to the cafeteria on a Monday and ask the first 25 students who purchase a lunch at the cafeteria if they are satisfied with the food. Do you think this is a good way for Diego to select his sample? Explain your reasoning.

Answers

Final answer:

Diego's method may introduce bias by not representing all student subgroups, suggesting that a random, stratified random, or systematic sampling method would better reflect student satisfaction with cafeteria food.

Explanation:

The question asks if selecting the first 25 students who purchase a lunch at the cafeteria is a good way for Diego to sample students to determine satisfaction with the cafeteria food. This sampling method may lead to bias because it does not represent all subgroups within the school population equally. For instance, it may only capture the opinions of students who already have a preference for cafeteria food, thus overlooking those who avoid it due to dissatisfaction. A better approach would be a random sampling method, where every student has an equal chance of being selected, ensuring a more accurate reflection of the entire student body’s opinion.

To improve the survey, Diego could consider using a stratified random sample, where the school population is divided into strata, such as grade levels or lunch periods, and then a random sample is taken from each stratum. This approach helps ensure that all segments of the student population are represented. Alternatively, a systematic sampling method, where every nth person is selected from a list or a line, could provide a more structured yet still random selection process compared to Diego's original plan.

Diego's approach is convenient but prone to bias. Random sampling across various days would improve representativeness and accuracy.

Diego's approach to surveying the students about cafeteria satisfaction has both strengths and weaknesses. Let's break down the pros and cons step by step:

1. **Convenience**: Approaching students during lunchtime in the cafeteria is convenient because it allows Diego to access a large number of students in one place and at a time when they are likely to be available.

2. **Sampling Bias**: However, selecting only the first 25 students who purchase lunch on a Monday might introduce sampling bias. For example, if there is a rush in the cafeteria during that time, Diego might end up surveying students who are in a hurry and may not accurately represent the entire student population.

3. **Limited Sample Size**: The sample size of 25 students is relatively small. While a larger sample size is not always necessary for accurate results, a larger sample size generally leads to more reliable findings. With only 25 students surveyed, there's a risk of the results being skewed by chance variations.

4. **Day of the Week Bias**: Monday might not be the best day to conduct the survey. Students' satisfaction with cafeteria food might vary depending on the day of the week due to factors like menu rotation or weekend leftovers. Therefore, surveying only on Mondays might not provide a comprehensive picture of overall satisfaction.

5. **Response Bias**: There's also the potential for response bias. Students who are particularly satisfied or dissatisfied with the food might be more likely to respond to Diego's survey, leading to results that don't accurately reflect the general sentiment of all students.

6. **Alternatives**: A better approach might be to conduct the survey at different times and days of the week to capture a more diverse range of student experiences. Additionally, Diego could use random sampling techniques to ensure that every student has an equal chance of being surveyed, reducing the risk of bias.

In summary, while Diego's approach is convenient, it may not yield the most accurate or representative results due to potential sampling bias, limited sample size, and other factors. To improve the validity of the survey findings, Diego should consider adjusting his sampling method and survey timing.

if 2500 is invested at a rate of 11% compounded continously, find the balance in the account after 4 years. Use the formula A=Pe^rt​

Answers

The balance in the account after 4 years, compounded continuously at 11%, is approximately $3884.25.

The formula for continuous compounding is given by [tex]\(A = Pe^{rt}\)[/tex], where:

- [tex]\(A\)[/tex] is the final amount,

- [tex]\(P\)[/tex] is the principal amount (initial investment),

- [tex]\(e\)[/tex] is the mathematical constant approximately equal to 2.71828,

- [tex]\(r\)[/tex] is the interest rate, and

- [tex]\(t\)[/tex] is the time in years.

In this scenario, [tex]\(P = $2500\)[/tex], [tex]\(r = 0.11\)[/tex] (11% expressed as a decimal), and [tex]\(t = 4\)[/tex] years. Plugging these values into the formula:

[tex]\[ A = 2500 \times e^{(0.11 \times 4)} \][/tex]

Calculate the exponent:

[tex]\[ A = 2500 \times e^{0.44} \][/tex]

Using the approximate value of [tex]\(e \approx 2.71828\):[/tex]

[tex]\[ A \approx 2500 \times 2.71828^{0.44} \][/tex]

[tex]\[ A \approx 2500 \times 1.5537 \][/tex]

[tex]\[ A \approx 3884.25 \][/tex]

Therefore, the balance in the account after 4 years, with an initial investment of $2500 at a continuously compounded interest rate of 11%, is approximately $3884.25.

The factors are: (3a+2b +ab-6)(3a+2b -ab+6)

Step-by-step explanation:

[tex](a^2-4)(9-b^2)+24ab[/tex]

We need to solve the above expression using factorization.

Multiplying (a^2-4)(9-b^2)

9(a^2-4)-b^2(a^2-4) + 24ab

9a^2 -36 -a^2b^2+4b^2 + 24ab

Rearranging:

9a^2 + 4b^2 +24ab -36 -a^2b^2

We try to make perfect square of the form a^2+2ab-b^2

We have 24ab that can be written as 12ab + 12ab

Now, we can arrange the above equation:

9a^2 +12ab+ 4b^2 -(a^2b^2-12ab +36)

(3a)^2 +2(3a)(2b) + (2b)^2 -((ab)^2 -2(ab)(6)+(6)^2)

The perfect square will be:

(3a+2b)^2 - (ab-6)^2

Now We know a^2 - b^2 = (a+b)(a-b)

Here a = 3a+2b , b=ab-6

So,

(3a+2b +(ab-6))(3a+2b - (ab-6))

(3a+2b +ab-6)(3a+2b -ab+6)

So, the factors are: (3a+2b +ab-6)(3a+2b -ab+6)

if f=(2,3),(5,7),(5,4),(9,1), what is the range

Answers

Answer:  [tex]Range:[/tex]{[tex]1,3,4,7[/tex]}

Step-by-step explanation:

We know that, by definition, the Domain is the set of all the x-coordinates of the ordered pairs  and the Range is the set of all the y-coordinates of the ordered pairs.

Therefore, given [tex]f=(2,3),(5,7),(5,4),(9,1)[/tex], you can observe that the set of all second elements of ordered pairs (the values of "y") is the following:

{[tex]3,7,4,1[/tex]}

 Therefore, we can conclude that if [tex]f=(2,3),(5,7),(5,4),(9,1)[/tex] , then the range is:

 [tex]Range:[/tex]{[tex]1,3,4,7[/tex]}

Answer:

The range of f is {1 , 3 , 4 , 7}

Step-by-step explanation:

* Lets revise the relation

- f is a relation between x and y

- x is the input of the relation

- y is the output of the relation

- x is called the domain of the relation

- y is called the range of the relation

- The range is the corresponding value to x

* Now lets solve the problem

∵ f = {(2 , 3) , (5 , 7) , (5 , 4) , (9 , 1)

∵ x = {2 , 5 , 9}

∴ The domain of f is {2 , 5 , 9}

∵ y = {1 , 3 , 4 , 7}

∴ The range of f is {1 , 3 , 4 , 7}

At a concert
3 adult and 4 child cost £23
1 adult and 5 child cost £15
Work out the cost of an adult ticket and the cost of a child ticket.

Answers

Answer:

adult = £5

child = £2

Step-by-step explanation:

a = adult c = child

3a + 4c = 23

1a + 5c = 15

multiply second equation by 3 and rewrite

3a + 4c = 23

3a + 15c = 45

subtract

0 - 11c = - 22

-11c = -22

11c = 22

c = £2

subsitute into one of the equations and solve for a

1a + 5c = 15

a + 5(2) = 15

a + 10 = 15

a = £5

Final answer:

The question can be solved using systems of linear equations. The cost of an adult's ticket is £5, and the cost of a child's ticket is £2.

Explanation:

The problem given can be solved using systems of linear equations. We can denote the cost of an adult's ticket as 'a' and the cost of a child's ticket as 'c'. Then you set up two equations:

3a + 4c = 23a + 5c = 15

To solve the system, we can multiply the second equation by 3:

3a + 15c = 45

Now we subtract the first equation from this one:

(3a + 15c) - (3a + 4c) = 45 - 2311c = 22

If you divide by 11, you get c=2. Now, substitute c into the second initial equation: a + 5*2 =15, and you get that a=5. Therefore, the cost of an adult's ticket is £5 and the cost of a child's ticket is £2.

what is the vertex and equation for axis of symmetry of f(x)= x^2 +4x+3

Answers

Answer:

Vertex: (- 2, -1)

axis of symmetry: x= - 2

Step-by-step explanation:

f(x)=x^2+4x+3

f(x)=(x^2+4x+4)+3-4.......complete the square

f(x)=(x+2)^2-1...................write in vertex form

Answer:

see explanation

Step-by-step explanation:

Given a quadratic function in standard form ax² + bx + c : a ≠ 0

Then the axis of symmetry and the x- coordinate of the vertex, since the vertex lies on the axis of symmetry is

x = - [tex]\frac{b}{2a}[/tex]

f(x) = x² + 4x + 3 ← is in standard form

with a = 1, b = 4, hence

x = - [tex]\frac{4}{2}[/tex] = - 2

Equation of axis of symmetry is x = - 2

Substitute x = - 2 into f(x) for corresponding y- coordinate of vertex

f(- 2) = (- 2)² + 4(- 2) + 3 = 4 - 8 + 3 = - 1

Hence vertex = (- 2, - 1)

Which of the following functions is graphed below?

Answers

Answer:

C

Step-by-step explanation:

looking at the graph, we see a parabola shifted up 6 units. the function is f(x) = x² + 6

we also see a line with a reflection on the y axis and a vertical shift up 6 units. the function is f(x) = -x + 6

x² + 6 is graphed like a normal parabola (u shaped graph) with an open circle on (3,15). the x coordinate is whats important here, which is 3. we see that there are no values to the right of 3, and only to the left of 3. we can say that the statement x < 3 is true of the parabola, as any value less than 3 is a solution to the parabola.

for -x + 6, we see a line graphed with an closed circle on approximately (3,3). again, the x-coordinate is important here which is 3. the line only goes to the right of 3, meaning the inequality x ≥ 3 is true of the line as any value greater than or equal to 3 is a solution

looking at our answer choices we need to find the following answer:

x² + 6 x < 3 and -x + 6 x ≥ 3

this answer would be C

0.5 kilograms equal to how many ounces? Round to the nearest tenth

Answers

Hello!

The answer is:

There are 17.6 ounces in 0.5 kilograms.

Why?

To calculate how many ounces are in 0.5 kilograms, we need to use the following factor:

[tex]1Kg=35.274ounces[/tex]

So, converting we have:

[tex]0.5Kilogram*\frac{35.274ounces}{1Kilogram}=17.637ounces=17.6ounces[/tex]

Have a nice day!
