Answer:
g(g(-2))
g(-8)
-32
This is the correct solution
The answer to "12x-(4y+7z) for x=9 y= 4 and z = 2" is 78.
The slope would be 0
This is basically how you do it if you need more help let me know
9/2{8-x}+36=102-5/2{3x+24}
you first use 9/2 to open brackets
9/2*8=36,
9/2*x=9/2x
36-9/2x=102-5/2{3x+24}
5/2*3x=15/2x+60
36-9/2x=-15/2x-60
36+60=15/2x+9/2x
96=12x you then divide and the answer obtained will be 8.
x=8
