Hi Larry
x^3 - 168 = [ 24(x-2)] / 2
x^3 - 168 = (24x - 48)/2
x^3 - 168 = 12x - 24
Subtract 12x - 24 to both sides
x^3 - 168 - (12x - 24) = 12xx - 24 - (12x - 24)
x^3 - 12x - 144 = 0
Now, factor the left sides
(x - 6)(x^2 + 6x + 24) = 0
Set factors equal to 0
x - 6 = 0 or x^2 + 6x + 24 = 0
x = 0 + 6 or x^2 + 6x + 24 - 0
x = 6
Answer : X = 6
Good luck !
Answer:
Option A. 17.6%
Step-by-step explanation:
Since it is given that stems are in whole percent and leaves are tenths of percent which means if we take the first steam value of 5 7;
it means that 5 is whole percent and 7 will be written as 
= 0.7 percent which as a whole indicate that the first stem leaf represent 5.7% of residents aged 65 and over.
Now the highest percent of older residents for Florida will be the last stem leaf in the data given as 17 + 0.6 will represent 17.6% which is the highest among all others.
5.7% is the lowest of them all and there is no value as of 176% in the given stem leaf plot data.
Therefore option A id correct with 17.6% percent as of Florida.
Answer:
Step-by-step explanation:
The average rate of change of a function f between a and b (a< b) is :
R =[f(b)-f(a)] ÷ (a-b)
●●●●●●●●●●●●●●●●●●●●●●●●
Let R be the average rate of change of this function
f(6) = 2×6^2 - 7×6 = 72-42 = 30
f(2) = 2×2^2 - 7×2 = 8-14 = -6
R = [f(6) - f(2)]÷ (6-2)
R = [30-(-6)] ÷ 4
R = -36/4
R = -9
■■■■■■■■■■■■■■■■■■■■■■■■■
The average rate of change of this function is -9
