PLS HELP! If f(x) = -9x + 12, and f(x) = -6, find x.
aivan3 [116]

Answer:

2

Step-by-step explanation:

You can rewrite thosee two equations as -9x+12=-6, because f(x)=f(x)

Now isolate x

-9x+12=-6

-9x+12-12=-6-12 (subtract 12, subtraction property of equality)

-9x=-6-12

-9x=-18 (simplify)

-9x/-9=-18/-9 (divide by 9, division property of equality)

x=2

The average annual income, I, in dollars, of a lawyer with an age of x years is modeled with the following function:
Eduardwww [97]
I = -425x^2 + 45500x - 650000
For I to be maximum, dI/dx = 0
dI/dx = -850x + 45500 = 0
x = 45500/850 = 53.53

Therefore, maximum I = -425(53.53)^2 + 45500(53.53) - 650000 = 567,794.11

Therefore, <span>the maximum average annual income, in dollars, a lawyer can earn</span>  is $567,794
