F(x) = x²-81
g(x) = (x-9) -1(x+9)
= (x-9) -x-9
g(x) • f(x)
= [x²-81 ] • [ (x-9) -x-9 ]
=[ x²-81 ] • [ (x-x -9-9) ]
= [ x²-81 ] •[0-18]
= [ x²-81] •[ -18]
= -18•x² +-81•-18
= -18x²+1458
Answer:
3000
Step-by-step explanation:
If they spend 60% of their income, they save 40% of their income
Let x be their income
x * 40 % = 1200
.40x = 1200
Divide each side by .4
x = 1200/.4
x =3000
You need to know the value of X to determine whether or not the equation is true.
