Answer:
p(w) - - - - - - p = 0.5w ; for 0 < w ≤ 8
p(w) - - - - - - p = 4 ; for w < 8 and w ≤ 12
Step-by-step explanation:
Price, p of weight of a toughurt serving :
p(w) - - - - - - p = 0.5w ; for 0 < w ≤ 8
p(w) - - - - - - p = 4 ; for w < 8 and w ≤ 12
ANSWER : Rozalie spent 6.73 hours at the garage
rate of change = $2.75
base fee = $7.50
set up your equation:
2.75h + 7.5 = 26
($2.75/hour plus the base fee of $7.50 equals the total amount spent, $26)
Now just solve for h
2.75h + 7.5 = 26
2.75h = 18.5
h = 6.727273 (rounded)
h = 6.73
So the answer would be Rozalie spent about 6.73 hours at the garage.

Answer:
(goh) (4) = 7
Step-by-step explanation:
(goh) (x) = g(h(x))
Plug in
g(h(x)) = 5(√x) - 3
if x = 4 then
g(h(4)) = 5(√4) - 3
g(h(4)) = 5(2) - 3
g(h(4)) = 10 - 3
g(h(4)) = 7
Answer:
Step-by-step explanation:
23x-12-4x+5x
24x-12 combine the 23x-4x+5x to get 24x
19-14+3x+12x
15x+5 19-14=5 3x+12x=15x
6x+19-14x+9
-8x+28 -14x+6x= -8x 19+9=28
