Question

I really need some help please!!! More than willing to give medal.

Answer 1

Tamara has decided to start saving for spending money for her first year of college. Her money is currently in a large suit case under her bed, modeled by the function s(x) = 450. She is able to babysit to earn extra money and that function would be a(x) = 6(x − 2), where x is measured in hours. Explain to Tamara how she can create a function that combines the two and describe any simplification that can be done.

Answer 2

Her money is 450
she earns money for f(x) = 6(x-2)
f(x)= 6x - 12


450 + (6x-12)
450 + (12 -12)
450 + 6(2) - 12 is the same
I would leave it as (6x-12) + 450 = f(x)

Answer 3

And any simplification that can be done?

Answer 6

Do you think by any chance you can help me with this one too, its late and I'm tired and I just want to finish.

Answer 7

Tommy has some money at home from his graduation modeled by the function h(x) = 350. He read about a bank that has savings accounts that accrue interest according to the function s(x) = (1.04)x − 1. Tommy is thinking about putting his money into the savings account to gain interest. Using complete sentences, explain to Tommy how he can combine his functions to create a new function, and explain what this new function means.

Answer 8

you plug them in together, as in, s(h(x)... Therefore, you'd replace the variable in s(x) with the constant in h(x). This is ofcourse assuming there is no variable defining time. Therefore it'd be (1.04)*350 - 1.
