(f○g)(x)=√(7(x+8))
(f○g)(x)=√(7x+56)
Since there is no real square root of a negative value, the smallest value in the domain would make the radicand equal to zero. x=-8 is the smallest number in the domain of (f○g)(x)
(y x .12) x .3 = the total cost
6x - 3.5 = -15.5
Add 3.5 to both sides
6x = -12
Divide by 6
x = -2
Carly has the correct response
Answer:
Step-by-step explanation:
.25+.24+2^=1.8-25/2=12
Answer: x = 16
Step-by-step explanation:
24 + 2 + 4x = 90
26 + 4x = 90
4x = 64
x = 16
