Answer: 11 boxes of cards for $72
Step-by-step explanation:
Brennan's equation would be
y=6x+6
Gabriel's Equation would be
y=5x+17
when they spend the same amount the equations will be equal
6x+6=5x+17
x+6= 11
x=11
so 11 boxes they would spend the same
To figure out cost, put 11 into the first equations
y=6(11)+6= 66+6= 72
y=5(11)+17= 55+17 = 72
so they each spent $72

Answer:
-16
Step-by-step explanation:
f(x)=-8x+8 and g(x) = sqrt x-9
(f•g)(18)=f(g(18))
g(18)=sqrt(18-9)=sqrt9=3
f(3)=-24+8=-16
