Answer:
(6,-6)
Step-by-step explanation:
1. -10x-15y=30
-10x-15y+15y=30+15y
-10x/-10=30+15y/-10
x=-3 -3/2
plug in the other equation and solve for y
-9x-5y=-24
-9(-3-3/2)-5y=-24
y=-6
plug -6 in for y in one of the original equations
-9x-5y=-24
-9x-5(-6)=-24
solve for x
x=6

No its not true and im sorry if this is wrong
Answer:
D
Step-by-step explanation:
To inverse a function, switch the y for x and x for y and solve for y
f(x) = 2/(x-3)
y = 2/(x-3)
x = 2/(y-3)
x*(y-3) = 2
y-3 = 2/x
y = 2/x-3
y = 2/x - 3x/x
y = 2+3x/x
