The cost of producing x soccer balls in thousands of dollars is represented by h(x)=5x+6 the revenue is represented by k(x)=9x-2 which expression represents the profit (k-h)(x) of producing soccar balls
A) 14x-8
B)14x+4
C)4x-8
D)4x+4

C).  4x - 8.

Step-by-step explanation:

(k-h)(x) = k(x) - h(x)

= 9x - 2 - (5x + 6)        Distributing -1 over the parentheses:

= 9x - 2 - 5x - 6

= 4x - 8 = the profit.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
