Answer:
g(f(-1)) = 2
Step-by-step explanation:
f(x) = 2 + x
g(x) = 3 - x
if you need to find g(f(-1)); find f(-1) first
f(-1) = 2 + (-1) = 1
f(-1) =1; now plug this into g(1)
g(1) = 3 - 1 = 2
-36 i think i dont really know sry!! :(
Answer:
r=15
Step-by-step explanation:
you would add 6 to the right side of the equation which would make it 3r = 45. Then you would divide 45 by 3, equaling 15. So that ends up with r = 15.
Okay so first you distribute to both sides(the arrows). then you subtract 5y to both sides and bring everything down. then you subtract 7 to both sides and get -27=9y and divide by 9 to get the y alone .
Answer:
478.5
Step-by-step explanation:
Considering the fact that the 2 after the g is not a power, then
400 x 0.6 x 2 = 480
0.9/0.6 = 1.5
480 - 1.5 = 478.5
