(-4)(-2)= 8
8(-5)= -40
Answer: -40
"Parallel" means the same, which means the slope you find. The formula for slopes is y=mx+b, so we need to put this equation in the right order for that. ('m' is the slope.)
Add 4x to each side, and get -3y=16+4x. Rearrange it to get it in the right order (y=mx+b).
This is -3y=4x+16. So the number in front of 'x' is 'm', which is the slope. You never actually see 'm', it is represented by a number. So four is the slope.
she had 98 but spent 10.85 so she now has:
98-10.85 = 87.15
skateboard cost 64
87.15 -64 = 23.15 is what she can spend on cookies
23.15 / 1.65 = 14.03 she can't buy more than 14 cookies
so answer is c. n ≤ 14
She bought 8 apples..................
