<u>Turn 4 7/9 into an Improper Fraction</u>

Multiply 4*9 and get 36. Now add 7 and get 43 (Denominator stays the same)

4 7/9 = 43/9

<u>Add</u>

29/3 + 43/9 = 130/9

2. Name two ways of finding the rate of change of a<br> linear function
Anvisha [2.4K]

Answer:

When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h)2 Therefore, the slope of the secant line between any two points on this function is 2x + h.
