1/4n+1 1/2+2-1 2/4n-32

a. 1/4n-28

b. 1 1/4n28-1/2

c. -1 1/4n-281/2

d. -1 1/4n+34

your answer is -11n -98/4

Step-by-step explanation:

simplify to 1/3

then get another fraction from further multiplication and find 11/2

lcm is 4  

your answer is -11n -98/4 give the other guy brainliest

  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).

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
