Question 4: The answer is D, The rate of change is 2/3 and the initial value is -2.

The initial value is when x = 0, and 2/3 * 0 - 2 = -2.

The rate of change of a linear function is the coefficient of x, which is 2/3.

Question 5: The answer is A, The bucket starts with 5 gallons, and is being filled at 2 gallons per minute.

It starts with 5 gallons since the initial value is 5. (2 * 0 + 5 = 5).

It's being filled at 2 gallons per minute since the rate of change is a positive 2. If it was negative 2, it would be drained.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
