Answer:
1 x≠0
undefined x=0
Step-by-step explanation:
As long as x is not 0
(4x)^0
=1
Anything to the power of 0 is 1 (except for 0
If x =0 then it is undefined
F(h(3))
h(3) = 3^2 + 1 = 9 + 1 = 10
f(10) = 2(10) - 1 = 19
g(f(-5))
f(-5) = 2(-5) -1 = -10 - 1 = -11
g(-11) = 3(-11) = -33
f(f(6))
f(6) = 2(6) - 1 = 12 - 1 = 11
f(11) = 2(11) - 1 = 21
I think I already did the others on a separate question.
Answer:
C)
Step-by-step explanation:
=x/x+6 ÷ x+6/x

Answer:
50 % alcohol solution = 10 millimetres
30 % alcohol solution = 90 millimetres
Step-by-step explanation:
two equations can be derived from this question
x + y = 100 equation 1
0.3x + 0.5y = 100 x 0.32 = 32
0.3x + 0.5y = 32 equation 2
where :
x = 30% alcohol solution
y = 50% alcohol solution
multiply equation 1 by 0.3
0.3x + 0.3y = 30 equation 3
subtract equation 3 from 2
0.2y = 2
y = 10
substitute for y in equation 1
x + 10 = 100
x = 100 - 10
x = 90
