11. y=-1/3x-4
Plug the slope into m in y=mx+b and then plug in your point and solve for b. You get C
12. Parallel means it has the same slope or the same m, so the -1/2 stays the same and you plug that and your point into the y=mx+b and solve for b again. You get D, y=-1/2x-9
13. Perpendicular means that the slope is the opposite reciprocal so you flip it and multiply it by -1. You then plug that in for your slope and plug in your points and you get A, y=9x+13

Answer:
-4 = ?
Step-by-step explanation:
<u>Step 1: Substitute -1 for x</u>
7x^3 + 5x^2 - 2 = ?
7(-1)^3 + 5(-1)^2 - 2 = ?
7(-1) + 5(1) - 2 = ?
-7 + 5 - 2 = ?
-4 = ?
Answer: -4 = ?
2, 8, 32, 128,
Multiply by 4 for each number
8/2= 4
32/8= 4
128/32= 4
128*4=512
512*4= 2,048
Answer: D 512, 2,048
