1 less than the quotient of four and a number X​

Answer:

Solution (-2, 7)

Step-by-step explanation:

2x + 3y = 17      (1)

5x + 6y = 32    (2)

Using elimination method

Multiply (-2) to the equation (1)

-4x - 6y = -34  

Now you have 2 new equations

-4x - 6y = -34

5x + 6y = 32

----------------------------Add

x = -2

Substitute x = -2 into 2x + 3y = 17

2(-2) + 3y = 17

- 4 + 3y = 17

3y = 21

 y = 7

Solution (-2, 7)

Final answer:

The solution to the system of equations 2x + 3y = 17 and 5x + 6y = 32 using the elimination method is x = -2 and y = 7.

Explanation:

To solve the system of equations using the method of elimination, we manipulate the equations to make the coefficients of either x or y the same, and then subtract one equation from the other to eliminate that variable. Let's consider the given equations:

2x + 3y = 17 (Equation 1)

5x + 6y = 32 (Equation 2)

We can see that the coefficients of y are in the ratio of 3:6 or 1:2. To use elimination, we want the coefficients to match, so we can multiply Equation 1 by 2:

(2)(2x) + (2)(3y) = (2)(17)

4x + 6y = 34 (New Equation 1)

Now we can subtract the new Equation 1 from Equation 2:

(5x + 6y) - (4x + 6y) = 32 - 34

5x - 4x + 6y - 6y = -2

x = -2

Now that we have a value for x, we can substitute it back into one of the original equations to solve for y. Let's substitute x into Equation 1:

2(-2) + 3y = 17

-4 + 3y = 17

3y = 17 + 4

3y = 21

y = 7

The solution to the system of equations is x = -2 and y = 7.

Monarch butterflies flap their wings 12 times per second. Over the course of one hour, which is 3600 seconds, they flap their wings approximately 43,200 times.

Monarch butterflies flap their wings about 12 times per second. To figure out how many times they flap their wings in 1 hour, we need to calculate the total number of seconds in an hour and then multiply that by the flapping rate.

Step 1: Calculate the number of seconds in one hour.

Step 2: Multiply the number of seconds by the flapping rate.

So, Monarch butterflies flap their wings approximately 43,200 times in one hour.

Answer:

Step-by-step explanation:

The best first step to solve the equation -2(x+3)=-10 is to distribute the -2 across the parentheses, simplify the equation, and then solve for x.

Checking the answer by substituting the value of x back into the original equation ensures the solution is correct.

When solving the equation -2(x+3)=-10, the best first step to simplify the equation is to distribute the multiplication of -2 across the parentheses.

This is done to eliminate the parentheses and simplify the equation into its simplest form. After distribution, you would then have the simplified equation -2x - 6 = -10.

From there, you can proceed to solve for x by adding 6 to both sides of the equation to isolate the term with x, then dividing both sides by -2 to find the value of x.

Here are the basic problem-solving steps:

Once you've calculated the value of x, it's important to check the answer to ensure it is reasonable.

You can do this by substituting the value of x back into the original equation.

Answer:

Option D is correct.

Step-by-step explanation:

We need to find the pattern in the values as the exponents increase.

First value is 1/3

if we multiply 3 with 1/3 i.e. 1/3*3 we get 1

The next value is 1 in the table.

Now, if we multiply 1 with 3 i.e. 1*3 we get 3

The next value is 3 in the table.

Now, if we multiply 3 with 3 i.e 3*3 we get 9

So, the next value is 9 in the table.

So, if we multiply 3 with the previous value we get the next value in the table.

Hence Option D multiply the previous value by 3 is correct.

The answer is:

The fourth graph.

We are given the following equation:

[tex]f(x)=x[/tex]

Then, we need to find the graph of f(x+2) that will be equal to:

[tex]f(x+2)=x+2[/tex]

[tex]y=x+2[/tex]

Now, finding the x-axis interception, making "y" equal to 0, we have:

[tex]0=x+2[/tex]

[tex]-2=x[/tex]

Therefore, the x-axis interception point is located at (-2,0), it matches with the fourth graph.

Now, finding the y-axis interception, making "x" equal to 0, we have:

[tex]y=x+2[/tex]

[tex]y=0+2=2[/tex]

Therefore, the y-axis interception point is located at (0,2), it matches with the fourth graph.

Hence, we have that the graph of f(x+2) is the fourth graph since the second graph function cuts the x-axis at -2 and the y-axis at 2.

Answer:

f(3) = 9

Step-by-step explanation:

Wherever you see an x on the right, put a 3 in for that x

f(x) = 2x^2 + x - 12

f(3) = 2*(3)^2 + 3 - 12

f(3) = 2*9 + 3 - 12

f(3) = 18 + 3 - 12

f(3) = 9

ANSWER

[tex]p(x) = 6x - 15[/tex]

EXPLANATION

The revenue from selling x necklaces is

[tex]r(x) = 10x[/tex]

The cost of buying x necklaces is

[tex]c(x) = 4x + 15[/tex]

The profit from selling x necklaces is

[tex]p(x) = r(x) - c(x)[/tex]

We substitute the functions to get;

[tex]p(x) = 10x- (4x + 15)[/tex]

[tex]p(x) = 10x- 4x - 15[/tex]

[tex]p(x) = 6x - 15[/tex]

Therefore the function for the profit is

[tex]p(x) = 6x - 15[/tex]

The correct answer is D

EXPLANATION

The given quadratic expression is

[tex]3 {x}^{2} + 8x = - 1[/tex]

Divide through by 3

[tex]{x}^{2} + \frac{8}{3} x = - \frac{1}{3} [/tex]

We now add the square of half the coefficient of x because the coefficient of the quadratic term is now unity.

The constant we would add is

[tex] {( \frac{4}{3} )}^{2} = \frac{16}{9} [/tex]

The correct answer is D

Answer: Option D.

Step-by-step explanation:

Given the quadratic equation [tex]3x^2+8x=-1[/tex], you can observe that the leading coefficient is not 1, then you have to divide both sides of the equation by 3:

[tex]\frac{3x^2+8x}{3}=\frac{-1}{3}\\\\x^2+\frac{8}{3}x=\frac{-1}{3}[/tex]

Now, you can observe that the coefficient of the x-term is [tex]\frac{3}{8}[/tex], so you must divide it by 2 and square it. Then you get:

[tex](\frac{\frac{8}{3}}{\frac{2}{1}})^2=\frac{16}{9}[/tex]

Therefore, you must add [tex]\frac{16}{9}[/tex] to both sides of the equation.

Answer:

Step-by-step explanation:

Use Basic Proportionality Theorem (look at the picture).

Answer:

x = 5

Step-by-step explanation:

Using the rule of logarithms

[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]

Given

[tex]log_{2}[/tex](3x - 7) = 3, then

3x - 7 = 2³ = 8 ( add 7 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

The required solution of logarithmic expression  log2 (3x - 7) = 3 is x = 5. Option B is correct.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
To solve for x in the equation log2 (3x - 7) = 3, we first use the definition of a logarithm to change the logarithmic form to the exponential form.

log2 (3x - 7) = 3

2³ = 3x - 7

Next, we solve for x by adding 7 to both sides of the equation:

8  + 7= 3x - 7 + 7

15 = 3x

Finally, we divide both sides of the equation by 3:

x = 5

So, the solution of log2 (3x - 7) = 3 is x = 5.

Answer: If [tex]a=b[/tex] and [tex]b=c[/tex], then [tex]a=c[/tex]

Step-by-step explanation:

Let be "a", "b", and "c" all real numbers, the Transitive property of equalities states that :

If [tex]a=b[/tex] and [tex]b=c[/tex], then [tex]a=c[/tex]

You can observe that if two numbers are equal to the same number, then all this numbers are equal to each other.

For example, applying the Transitive property of equalities to:

[tex]x+3=5[/tex] and [tex]2x+1=5[/tex]

You can equate them:

[tex]x+3=2x+1[/tex]

Answer:

The correct answer option is: If a = b and b = c, then a = c.  

Step-by-step explanation:

The Transitive Property of Equality states that if one value, lets say [tex] a [/tex] is equal to another value, call it [tex] b [/tex], which is equal to another value, call it [tex] c [/tex], then the very first value [tex] a [/tex] would be equal to the third value [tex] c [/tex].

Answer:

Approximately 68%

Step-by-step explanation:

The number of potato chips in a bag is normally distributed with a mean of 71 and a standard deviation of 2, that is to say:

X ∼ N(µ, σ2) ⇒ X ∼ N(71, 4).

Now, to find the percentage of bags that contain between 69 and 73 potatos we need the help of a calculator.

Pluging the data into a calculator we get that the percentage of bags that contain between 69 and 73 potatos is 68.27% ≈ 68%.

The solution is: Approximately 68%

Answer:

Approximately 68% percent of bags contain between 69 and 73 potato chips.

Step-by-step explanation:

Number of chips in a bag is normally distributed.

Mean = 71

Standard deviation = 2

We know that in normal distribution, 34.1% of bags will fall with in one standard deviation on one side. On both sides within the range of 1 standard deviation, 34.1 + 34.1 = 68.2 % of bags will fall.

A table of normal distribution about mean is attached for better understanding.

Our range is:

69 to 73

71 - 2 to 71 + 2

71 ± 2

mean ± standard deviation

Our range is within 1 standard deviation. Hence, Approximately 68% of bags contain between 69 and 73 potato chips.

Answer:

No Solution

Step-by-step explanation:

Substitution means to replace the variable with the one provided, in this problem we have been given y = 2x, so we would simply replace the y variable in the second equation with 2x.

Review over what we have been given

y = 2x

-6x + 3y = 16

As explained above, substitute the y value in the second equation with the contents of the first equation.

-6x + 3(2x) = 16

In this step, you can solve for the value of x.

-6x + 6x = 16

Since both of the x variables cancel out, we cannot find the value of x since it equals to zero, which also means we cannot find the value of y.

0 = 16

Generally, we find the value of our x, then we would input that into the first equation to find the value of y.

But as stated above, there is no value of x, therefore there is no solution.

Answer:

C 40

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

y+10 + 2y + 50 = 180

Combine like terms

3y + 60 =180

Subtract 60 from each side

3y+60-60 = 180-60

3y = 120

Divide by 3

3y/3 = 120/3

y = 40

The sum of all the angles of a triangle is 180 degrees. To solve for y you can make a formula of the sum of the angles equal to 180 like so...

y + 10 + 2y + 50 = 180

Now you must combine like terms. This means that first numbers with the same variables (y) must be combined...

(y + 2y) + 10 + 50 = 180

3y + 10 + 50 = 180

Combine like terms 10 and 50...

3y + 60 = 180

Now bring 60 to the left side by subtracting 60 to both sides (what you do on one side you must do to the other). Since 60 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.

3y + 60 - 60 = 180 - 60

3y + 0 = 120

3y = 120

Next divide 3 to both sides to finish isolating x. Since 3 is being multiplied by x, division (the opposite of multiplication) will cancel 3 out (in this case it will make 3 one) from the left side and bring it over to the right side.

3y / 3 = 120 / 3

y = 40

C. 40
