Answer:

y=8/(P+q+4)

Step-by-step explanation:

we can find out that three items have y

so we can get them together Py+qy+4y=8

next(P+q+4)y=8 so y=8/(p+q+4)

Answer:

y = $\frac{8}{P+q+4}$

Step-by-step explanation:

Given

Py + qy = - 4y + 8 ← collect terms in y to the same side

Add 4y to both sides

Py + qy + 4y = 8 ← factor out y from each term on the left

y(P + q + 4) = 8 ← divide both sides by P + q + 4

y = $\frac{8}{P+q+4}$

The horsepower , H(s), required for a racecar to overcome wind resistance is given by the function : H(s) = 0.003s^2+0.07s-0.027

Average rate of change = [H(100) - H(80)] / (100 - 80)
H(100) = 0.003(100)^2 + 0.07(100) - 0.027 = 0.003(10000) + 0.07(100) - 0.027 = 30 + 7 - 0.027 = 36.973

H(80) = 0.003(80)^2 + 0.07(80) - 0.027 = 0.003(6400) + 0.07(80) - 0.027 = 19.2 + 5.6 - 0.027 = 24.773

Average rate of change = (36.973 - 24.773)/(100 - 80) = 12.2/20 = 0.61
