Answer:
f(x)= x2 - 2x + 3
0=3
x = ¤
Step-by-step explanation:
f(x) = -2x +19
0=-2x +19
2x=19
x =19/2
x= 9,1/2
x=9,5

A. -2/9
Step-by-step explanation:
the actual answer is -0.22222222222, but it is not listed so the next best answer is A
Answer:
72.55 ≤ x≤ 123.40
Step-by-step explanation:
c = 16.95x + 4.75,
We have to purchase a minimum of 4 games
Let x = 4
c (4) = 16.95(4) + 4.75
c(4) =67.8+4.75 = 72.55
This is the smallest amount we will spend
The most we will purchase is 7 games
Let x = 7
c (7) = 16.95(7) + 4.75
c(7) =118.65+4.75 = 123.40
This is the largest amount we will spend
The range is
72.55 ≤ x≤ 123.40
