Coach Manzer drove 350 miles in 5 hours and 455 miles in 6.5 hours. What is the constant rate of change?

70

Step-by-step explanation:

It gives you two data points, (5, 350) and (6.5, 455). Constant rate of change also means slope, and the formula for slope is (y(1)-y(2))/(x(1)-x(2)). If you plug in the data points you got for this, you get (350-455)/(6.5-5), which is equal to 105/1.5. Drop that in a calculator and you get 70.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
