Answer:
30
Step-by-step explanation:
15=30
x=60
cross multiply
30×x=60×15
30x=900
x=30

They’re all -4 ,, what exactly are you asking ?
Answer:
-8
Step-by-step explanation:
I've taken a picture of the way I solved the equation.
Answer:
g(x)=x-3
Problem:
If f(x+3)=x+6 find inverse of function f(x).
Step-by-step explanation:
Let u=x+3, then x=u-3.
Make this substitution into our given:
f(u)=(u-3)+6
Simplify:
f(u)=u+(-3+6)
f(u)=u+3
Now let's find the inverse of f(u)...
Or if you prefer rename the variable...
f(x)=x+3
Now, we are going to solve y=x+3 for x.
Subtracting 3 on both sides gives: y-3=x.
Interchange x and y: x-3=y.
So the inverse of f(x)=x+3 is g(x)=x-3.
Q= 3456
because, 3=4+7
4+5=9
5+6=11
and 3 x 2=6
