Answer:
x=30
Step-by-step explanation:
3(x+2)^3/5 +3=27
Subtract 3 from each side
3(x+2)^3/5 +3-3=27-3
3(x+2)^3/5 =24
Divide by 3
3/3(x+2)^3/5 =24/3
(x+2)^3/5 =8
Take everything to the 5/3 power to get rid of the exponent on the left side
(x+2)^3/5 ^ 5/3=8 ^ 5/3
Remember that a^b^c = a^ (b*c)
(x+2)^(3/5 * 5/3)=8 ^ 5/3
(x+2)=8 ^ 5/3
Replace 8 with 2^3
(x+2)=2^3 ^ 5/3
Remember that a^b^c = a^ (b*c)
(x+2)=2^(3 * 5/3)
x+2 = 2^5
x+2 = 32
Subtract 2 from each side
x+2-2 = 32-2
x=30
So f(x)=x+10 lets say
so if you put something into the function lets say 5 then the function will do something to it and give you an answer so if you put in 5 for x you would get 5+10 or 15
a function of a function
lets say
f(x)=2x-9
g(x)=7x+2
(g(x) is just another function represented by g instead of f)
so if you wanted to put g(x) as x into f(x) and put x in g(x) to 3
then f(g(x))=2(7x+2)-9 or f(g(3))=2(7*3+2)-9=2(23)-9=37
hope this helps

Answer:
x=2. y=1/2
Step-by-step explanation:
4x-2y=7. Equation 1
x+2y=3. Equation 2
Add the two equations
(4x+x) +(-2y+2y) =7+3
5x+0=10
5x=10 divide both sides by 5
X=2
Substitute x=2 in equation 2
2+2y=3
2y=3-2
2y=1. Divide both side by 2
Y=1/2
