Answer:
f( g(x)) = 18 *x*x + 6
g( f(x)) = 6xx + 18
Step-by-step explanation:
we want f (g(x)) and g( f(x))
f = 2xx + 6 g = 3x
f( g(x)) = 2 *(3x)*(3x) + 6 = 18 *x*x + 6
g( f(x)) = 3*(2 xx + 6 ) = 6xx + 18
.08x+.05(15000-x)=930
.08x+750-.05=930
.08x-.05x=930-750
.03x=180
X=180/.03=6,000 at 8%
(15000-6000)=9000 at 5%
Answer: 17
Step-by-step explanation:
To break even your revenue must be equal to your cost.

12x-2x=170
10x=170
x=170/10=17
So, Joan needs to sell 17 necklaces to break even.
