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:
1/38^8
Step-by-step explanation:
3.8 times 10 is 38
so it would be 38 to the power of -8 ( 38^-8 )
then you simplify
you have to rewrite the negative power
( you can't have negative power as numerator )
so you put it a part of the denominator
which switches the sign
hope this helps
To estimate the sum of difference of 1/8 +1/4, the method is as follows: Rule1 a/b +c/d = (axd) + (bxc) /bxd and Rule2: a/b - c/d = (axd) - (bxc) /bxd. let A=1/8 +1/4=(1x4) +(8x1) / /8x4=4+8 /32=12/32=3/8, and then A=1/8-1/4=4-8/32= -6/32= -3/16. So A=1/8 +1/4=3/8 and A=1/8 -1/4=-3/16Hope this helps. Let me know if you need additional help!
