Given f(x) = 3x − 10 and g(x) = 12x + 8, solve for (f + g)(x) and select the correct answer below. (f + g)(x) = 15x − 2 (f + g)(x) = 9x − 2 (f + g)(x) = 15x + 2 (f + g)(x) = 36x2 − 120x

First option is correct.

Step-by-step explanation:

Since we have given that

We need to find the addition of two functions i.e. f and g.

So, it becomes,

Hence, the addition of two functions is (f+g)(x)=15x-2.

Therefore, first option is correct.

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
