Answer:
B
Step-by-step explanation:
-3x+3y=-18 ➡3y=3x-18 ➡y=x-6
5x-2y=9➡-2y=-5x+9➡y=2.5x-4.5
2.5x-4.5=x-6
1.5x=-1.5
x=-1
y=-1-6
y=-7
B
Answer:
10
Step-by-step explanation:
He had 20 but gave his friend 10 apples and now he has 10. It is just subtraction.
20 - 10 = 10
1. replace f(x) with y
2. solve for x
3.replace x wieth f^-1(x) and y with x
f(x)=-3x+3
y=-3x+3
y-3=-3x
divide both sides by -3
(3-y)/3=x
f^-1(x)=(3-x)/3
