Two lines, A and B, are represented by equations given below:

Line A: y = x − 4

Line B: y = 3x + 4

Which of the following shows the solution to the system of equations and explains why?

Answers

Answer:

X=-4, y=-8

Step-by-step explanation:

x − 4 = 3x + 4

x - 4 - 3x = 3x - 3x + 4

-2x - 4 = 4

-2x - 4 + 4 = 4 + 4

-2x = 8

-2x/-2 = 8/-2

x = -4

then insert -4 for x then solve the equations.

WILL MARK BRAINLIEST Which of the following represents members of the domain of the graphed function?

Answers

Answer:

Step-by-step explanation:

Ngl I was confused for a minute. But domain is asking for the x-values and range is asking for the y-values.

You can see the points on the graph are (-4,1), (-2,2), (0, 3), and (2,4).

Because it is asking for the domain, it is asking for the X VALUES of the points you have found above. So the answer is {-4, -2, 0, 2}

So none of those answers look quite right

The reason I picked D is because it is the only one that contains the x values we picked. The rest have numbers outside the domain, such as 3, 4, 5, etc.

The answers D [-4,0,1]

Answer:

6. 4x

7. 3y

8. y - 4.5

9. 7/2x + 2

Step-by-step explanation:

x + x + x + x

Combine like terms by adding

4y - y

Combine like terms by subtracting

7y - 4.5 - 6y

Combine like terms by subtracting

1y - 4.5

y - 4.5

4.5 does not have the same variable as the other term in the expression, therefore we cannot do anything further to it

4x + 2 - 1/2x

Combine like terms by subtracting

One like term is a fraction so we must convert the whole number into a fraction with the same denominator

4/1x = ?/2

Cross multiply

4 × 2 = 1x × ?

8 = 2x

This is our new fraction: 8/2x because 4x = 8/2x

Substitute this new fraction into the expression

8/2x + 2 - 1/2x

Combine like terms by subtracting the numerators

7/2x + 2

Neither are like terms so they cannot be added together

Josh ran 14.8 km in the morning. After lunch, he continued running. When he finished the run, he had covered 31.1 km in all. Write an equation that can be used to find how far Josh ran after lunch.

Answers

14.8 + x =31.1
X equals how much he ran after lunch

Answer:

14.8 + x = 31.1

Step-by-step explanation:

This is the best equation to put as the answer.

If you want to solve it, this is how you would solve it.

14.8 + x = 31.1

Make it so that the variable x is by it's self.

14.8 + x - 14.8 = 31.1 - 14.8

x = 31.1 - 14.8

Now solve the subtraction problem.

x = 31.1 - 14.8 = 16.3

So, now you have your answer

x = 16.3

To make sure it's correct, use the addition method.

16.3 + 14.8 = 31.1

a 314 ft

b 63 ft

c 1256 ft

d 31 ft

Answers

Answer:

63ft

Step-by-step explanation:

Circumference (C) = 2pi x r

radius (r) = diameter/2

r = 10ft

C = 2(3.14)(10)

C = 62.8ft or 63ft

62.8 or 63 if you round up ig

In Harold’s class, there are 7 boys for every 6 girls. Identify three equivalent ratios to compare boys to girls.

Answers

Answer: The ratio of 6 /7 represent the number of boys to the number of girls in one classroom. You are given a total number of boys and girls.

So, your ratio has to represent how many boys to the total number of boys and girls in one classroom, or 13.

The proportion becomes, 6 / 13 = x / 78.

Cross multiply getting, 13 * x = 6 * 78

Divide by 13 to solve for x, or x = 36.

There are 36 boys in all of the classrooms and 42 girls in all of the classrooms.

The ratio of boys to girls in all of the classrooms is 36 / 42, or 6 / 7.
