Let f(x)=x2+7x+12 and g(x)=x2−9. What is (fg)(x)?

1) x+3x−4 where x≠3,4

2) x−4x+3 where x≠−3,4

3) x−4x+3 where x≠−3,3

4) x+4x−3 where x≠−3,3

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

the equation is not included but the answer is (1.50, 2.00, 2.75)
