Answer:
-22.5
Explanation:
Use the average rate of change equation
f(b)-f(a) / b-a
f(b) = f(0) = 3(.25)^0 = 3
f(a) = f(-2) = 3(.25)^-2 = 48
(3-48)/ 0-(-2)
(-45) / 2
-22.5
F (her fastest time) = 730 -31
S (her slowest time) =730 +31
The commutative property of multiplication states that u can " commute " the numbers, move them around, and the result will still be the same.
Example : 2 * 4 = 4 * 2
Therefore, mn = nm
