Step-by-step explanation:
f-g(x)=x³-2x²+12x-6-(4x²-6x+4)
=x³-6x²+18x-10

Replace f(x) with y
switch x and y
solve for y
replace y with g(x)
y=1/3x+2
x=1/3y+2
x-2=1/3y
3x-6=y
g(x)=3x-6
f(g(x)) should have the same result as g(f(x)) which should be x
f(g(x))=1/3(3x-6)+2=x-2+2=x
g(f(x))=3(1/3x+2)-6=x+6-6=x
the inverse is g(x)=3x-6
The dog weighs 17.48 pounds on Mars and 108.56 pound on Jupiter. Therefor, it will weigh 91.08 pounds less on Mars than on Jupiter.
Answer:
x=3
Step-by-step explanation:
y= -2
4x-3y=18
4x-3(-2)=18
4x-(-6)=18
4x+6=18
4x+6-6=18-6
4x=12

x=3
