m(slope)= change in y/change in x
m=-17-(-5)/3-1
m=17+5/2
m=22/2
m=11
\left[A \right] = \left[ \frac{ - \left( 5 - 3\,x - 2\,x^{2} - 2\,x^{3}\right) }{-1-x}\right][A]=[−1−x−(5−3x−2x2−2x3)] I hope helping this answer
The answer is c 10% of 89 is 8.9 so multiply by 3 you get 26.70
Replace the words with what you know
(Original cost)(6%)=5.25
(Original cost)(0.06)=5.25
(original cost)=5.25/0.06=87.5
