Final answer:

To solve the system of equations, use the method of substitution. Solve one equation for one variable and substitute the value in the other equation. Simplify and solve for the variable, then find the value of the other variable. The solution to the system is x = 7 and y = 2.

Explanation:

To determine the solution to the system of equations, we can use the method of substitution or elimination. Let's use the method of substitution.

Step 1: Solve one equation for one variable

From the first equation, we can isolate x: x = 1 + 3y

Step 2: Substitute the value of the variable in the other equation

Substitute x = 1 + 3y into the second equation: 3(1 + 3y) - 5y = 11

Step 3: Simplify and solve for y

Expand the equation and simplify: 3 + 9y - 5y = 11

Combine like terms: 9y - 5y = 11 - 3

Simplify: 4y = 8

Solve for y: y = 2

Step 4: Find the value of the other variable

Substitute the value of y into the first equation: x - 3(2) = 1

Simplify and solve for x: x - 6 = 1

x = 7

Therefore, the solution to the system of equations is x = 7 and y = 2.

The value of x will be 6 for the given triangle.

Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides.

According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Given that in the right-angle triangle, the hypotenuse is 10, the base is 8 and the perpendicular is x.

The value of x will be calculated as:-

x² = 10² - 8²

x² = 100  - 64

x² = 64

x = √36

x = 6

Step-by-step explanation:

Given the equation [tex]3^{x} = 38[/tex], to calculate the value of x the following steps must be carried out;

Step 1;

Take the natural logarithm of both sides

[tex]ln3^{x}=ln38\\ xln3 = ln38[/tex]

Step 2;

Divide both sides by ln3

[tex]xln3/ln3=ln38/ln3\\x=ln38/ln3\\x=3.31[/tex]

The value of x is 3.31 to the nearest hundredth

Final answer:

Jerry saves more money each month than Tom. Tom saves 35% of his salary, whereas Jerry spends 3/5 and saves the remainder, which is 2/5 of his salary. Assuming equal salaries, Jerry's savings are greater.

Explanation:

The question is asking us to compare how much Tom and Jerry save from their salaries. Let's assume each of them earns the same amount of salary, say for example $1000 (this figure is just for simplicity and can represent any currency or amount).

Tom saves 35% of his $1000 salary, which is 0.35 * $1000 = $350.

Jerry spends 3/5 of his salary, which is 3/5 * $1000 = $600. Therefore, he saves 2/5 of his salary because 1 - 3/5 = 2/5. So Jerry saves 2/5 * $1000 = $400.

Comparing the two, Jerry saves more each month since $400 (Jerry's savings) is greater than $350 (Tom's savings).

Answer:

its B

Step-by-step explanation:

No, x = 0 is not a valid solution for log(x + 7) + log(x − 3) = 17 .

Given,

log(x + 7) + log(x − 3) = 17

Here,

Substitute the value of x in the equation,

log(7) + log(-3) = 17

So,

log(-3) is not a valid number and thus its value does not exist .

Thus the equation can not be equated to 17 .

Hence option B is correct .

A triangle is a three-sided two-dimensional shape that can be classified based on side lengths and angle measurements. There are various types of triangles, including equilateral, isosceles, scalene, acute, right, obtuse, equiangular, and right-angled isosceles triangles.

A triangle is a three-sided two-dimensional shape. It is a polygon, which is a closed figure with straight sides. Triangles can be classified based on their side lengths, such as equilateral (all sides are equal), isosceles (two sides are equal), and scalene (no sides are equal). They can also be classified based on their angle measurements, such as acute (all angles are less than 90 degrees), right (one angle is 90 degrees), and obtuse (one angle is greater than 90 degrees). Additionally, there are special types of triangles like equiangular triangles (all angles are equal) and right-angled isosceles triangles (one angle is 90 degrees and two sides are equal).

Answer:

8.8 hours

Step-by-step explanation:

Happy paws cost equation

5.50h + 20

Wood watchers cost equation

6.75h + 9

Make the two equations equal

5.50h+20 = 6.75h+ 9

Collect the co-efficient of both sides.

6.75h- 5.50h= 20-9

1.25h= 11

Divide both sides by the coefficient of h

1.25h/1.25= 11/1.25

h= 8.8

Answer:

8.8 hours

Equation :20+5.50h = 9 + 6.75 h

Step-by-step explanation:

Hi, to answer this question we have to write a Cost equation for each case:

For Happy Paws the cost will be equal to the fixed cost (20) plus the product of the cost per hour (5.50) and the number of hours (h).

Happy paws cost: 20+5.50 h

Same process for Woof Watchers:

Woof Watchers cost = 9 + 6.75 h

If both costs are equal:

Happy paws cost=Woof Watchers cost

So:

20+5.50h = 9 + 6.75 h

Solving for h

20-9 = 6.75h-5.50h

11 = 1.25h

11/ 1.25 =h

8.8 = h

Answer: 5/25

5/50

Step-by-step explanation: If each part has 5 sections then it equals to 25 so you have a 5 out of 25 chance of getting it, The second time I added 25 twice since it says your spinning it twice, but you still only have 5 sections so you would have 5 out of 50

The calculated probability is 4 percent.

The student's question involves calculating the probability of two independent events occurring in sequence. Since each sector on the spinner is equal, the probability of landing on yellow for the first spin is 1 out of 5 or 0.2. Similarly, the probability of landing on blue for the second spin is also 1 out of 5 or 0.2.

Since these are independent events, their probabilities are multiplied to find the combined probability. Therefore, the probability of landing on yellow first and then on blue for the second spin is 0.2 * 0.2 = 0.04. This means there is a 4 percent chance of this outcome occurring.

Answer:

The percentage of the scores lying between 450 and 750 is 49.4%

Step-by-step explanation:

In this question, we are simply asked to calculate the percentage of the scores lying between a particular range.

The first thing to do here is to calculate the z score of both scores

Mathematically, z score = (x - mean)/SD

for score 450, we have ; z = (450-450)/120 = 0/120 = 0

For score 750, we have z = (750-450)/120 =

2.5

Now, we move on to calculate the probability before turning it into a percentage.

The supposed probability we are to calculate is as follows;

P(450 < x < 750) or P(0 < z < 2.5)

Using standard score table, P = 0.49379

The percentage is thus 49.4%

Answer:

Step-by-step explanation:

x - 2 is a factor. Therefore, P(2) = 0

P(x) = x³ - 4x² + 3x + c

P(2) = 0

2³ - 4*(2)² + 3*2 + c = 0

8 - 4*4 +6 +c = 0

8 - 16 + 6 + c = 0

-2 + c = 0

c = 2

Answer:

The probability that you don’t roll a 2 or a 3 = 2/3

Step-by-step explanation:

Formula for Probability = Number of Possible Outcomes / Number of events

We are told in the question that it is just a one number cube. This means that :

We have the Probability of rolling the 6 sided cube and obtaining, 1, 2, 3, 4, 5, and 6.

We are told in the question to find the probability of not rolling a 2 or 3.

Hence, this means

Probability( not a 2 or 3) = Probability( of a 1 or 4 or 5 or 6).

Therefore,

Probability (of rolling a 1) = 1/6

Probability (of rolling a 4) = 1/6

Probability (of rolling a 5) = 1/6

Probability (of rolling a 6) = 1/6

Therefore, Probability( not a 2 or 3) = Probability( of a 1 or 4 or 5 or 6) = P(1) + P(4) + P(5) + P(6)

= 1/6 +1/6 + 1/6 + 1/6

= 4/6

= 2/3.

Therefore, the probability that you did not roll a 2 or 3 ( i.e P( not 2 or 3)) = 2/3

Answer:

The graph of f has an inflection point at x = 0.

Step-by-step explanation:

An inflection point occurs when the second derivative changes signs.  Since f"(x) is decreasing and has an x-intercept at 0, it changes signs from + to -, so there is an inflection point at x = 0.

The statements "The graph of f has an inflection point at x = 0." is true

The meaning of X-INTERCEPT is the x-coordinate of a point where a line, curve, or surface intersects the x-axis.

From above reasons we can say that the statement "The graph of f has an x-intercept at x = 0." is true
