Question

3.Solve -2(2x - 3) = -6

4.Solve P = 2w + h for h.

5.Solve 3x - 5y = 15 for y.

6.y varies directly as the square of x. When x = 3, y = 54. Find y when x = 8.

7.y varies inversely as twice x. When x = 3, y = 8. Find y when x = 2.

8.y varies jointly with p and q. When p = 7 and q = 2, y = 70. Find y when p = 8 and q = 4.

9.What is the solution set for |2x - 6| - 7 = 7?

10.What are the solution intervals for |x + 5| + 3 > 7?

11.
On the graph of the equation 2x + 5y = -30, what is the value of the y-intercept?

12.What is the slope of the line that passes through (1, 4) and (1, -3)?

Answer 1

what are you thnking, that you can just post all of your question on here and we will answer them like robots

Answer 2

no i dont expect that, i just need help with them.
thats what this site is for. if you dont like it, then dont look at it

the site is to assit you to learn how to do these problems, not for you to cheat on your HW

Answer 4

that being said, lets do number 1

Answer 5

how would you begin?

Answer 6

with the parenthesis

Answer 7

exactly distribute the -2 into the parenthese

Answer 8

-4x-6

Answer 9

check it again, remeber : neg*pos=neg and neg*neg=pos
