Simplify the expression. 3(2y - 8) - 2y(5 - y)

2y^2 -4y -24

Step-by-step explanation:

start by expanding the first term, also known as multiplying the 3

3(2y-8) to get 6y-24

then -2y and (5-y) to get -10y and 2y^2

(dont forget to include the negatives when mulitiplying it out)

then combine like terms to get

2y^2 - 4y - 24

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

1 1/5
