By definition you have:
Keeping the above on mind, you can rewrite the expression as following:
Simplify:
(You can cancel out the like terms)
Answer:
Explanation:
f(x) = 3x+2
g(x) = x^3
(f • g)(x) = (3x+2)(x^3)
(f • g)(x) = 3x^4 + 2x^3
(f • g)(-5) = 3(-5)^4 + 2(-5)^3
(f • g)(-5) = 3(625) + 2(-125)
(f • g)(-5) = 1875 - 250
(f • g)(-5) = 1625
Answer: Choice C) $15
There are two ways to get this answer
Method 1 is to subtract 700-550 = 150 and then take 10% of that to get 15
We take 10% since this is the percentage Ricardo has to pay (the employer takes care of the other 90%)
Method 2 is to take 10% of 700 and 550 to get 70 and 55 respectively. Then subtract to get 70-55 = 15
Either way the answer is 15
