Answer:
D
Step-by-step explanation:
You can see, MN consists of the three lines in the picture. So you just need to sum them tougher in an equation with it's original value 81.
5 + 3x - 8 + 4x = 81
7x = 81 + 3
7x = 84 / : 7
x = 12
Given h(x)=5x-3 and j(x)=-2x.
So, j(2) = -2*2 = -4
So, h[j(2)] = h(-4)= (5*-4) -3 = -20-3 = -23
Hence option D is correct.
