Answer:
A) f(x) = 15x + 25; f(0) = 25
Step-by-step explanation:
x represents the amount of extra services, and 15x respresents the amount paid for all of the services. 25 represents the initial fee. f(0)=25 means that it cost $25 for a haircut with no extra services.
Let's say you have a haircut with two extra services. You would replace the x in the equation with the number of extra services, 2 in this case.
f(2)=15(2) + 25
f(2)=30+25
f(2)=55
It would cost $55 for a haircut with 2 extra services.

Answer:
False
Step-by-step explanation:
y=x-2 y=3x+4
Substitute the point into both equations and see if it is true
2=4-2
2=2 true
and
2=3*4+4
2 = 12+4
2 =16
False
It is not a solution
Answer:
x = 11.18
Step-by-step explanation:
According to the Pythagorean Theorem; (Leg1)² + (leg2)² = (Hypotenuse)²
10² + x² = 15²
100 + x² = 225
x² = 125
x = 
x = 11.18
