Hayden's checking account balance was $145.95. After two checks were cashed, each for the same amount, his balance was - $4.05. This problem can be represented by the equation below.
145.95 - 2x = -4.05
What does x represent?
A. amount of each cashed check
B. total amount of both cashed checks
C. beginning checking account balance
D. final checking account balance

Step-by-step explanation:

3=3=45u8

A. Amount of each cashed check.

Step-by-step explanation:

145.95 - 2x = -4.05

2x=150

X=75

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
