Answer:

y = 8

Step-by-step explanation:

Ok, so first you want to try to get y by itself. So you would subtract 6 from both sides.

3y + 6 = 30

-6 -6

3y = 24

Now, you want to divide 3 from both sides. Doing this will get the y by itself.

3y = 24

What is the midpoint of the line segment with endpoints(-2,-2) and (4,6)

Ann [662]

Answer:

The midpoint of points $(-2,-2)\ and\ (4,6)$ is $(1,2)$ .

Step-by-step explanation:

Given points are $(-2,-2)\ and\ (4,6)$ . We need to find the midpoint of the line segment.

The formula of finding midpoints between the point $(x_1,y_1)\ and\ (x_2,y_2)$ is

$(\frac{x_1+x_2}{2}),(\frac{y_1+y_2}{2})\ Equation(1)$

W have points $(x_1,y_1)=(-2,-2)$ . And $(x_2,y_2)=(4,6)$

Let us plug the value in Equation (1)

$(\frac{-2+4}{2} ),(\frac{-2+6}{2})$

$(\frac{2}{2}),(\frac{4}{2})\\ \\(1,2)$

So, the midpoint of points $(-2,-2)\ and\ (4,6)$ is $(1,2)$ .

Answer:

B. Negative

Step-by-step explanation:

We are given that x equals negative and y equals positive.

That means the fraction is negative multiplied by the 7y³ term, which is positive.

Negative times positive is negative, so B is our answer.
