You should repost i’ll try and answer then
Do you mean "perpendicular to k"? We have no line c there so I'm going with line k. First we need the slope of line k. Fitting those values into the slope formula we have

. So the slope of k is 9. The slope of a line perpendicular to k has the opposite sign and the fraction is flipped. The perpendicular slope then is -1/9.
Y=20+0.7x
x has to be per minute and 20 is alone bc that is the baseline
Answer:
-12w^3+32w^2-136w+80
Step-by-step explanation:
4(2-3w)(w^2-2w+10)
multiply first two:
(8-12w)(w^2-2w+10)
multiply:
8w^2-16w+80-12w^3+24w^2-120w
simplify:
-12w^3+32w^2-136w+80
