What is the rule for (fg)(x) for functions f(x)=x^2-9 and g(x)=2x
2x²-7x

2x^3+

2x^3 +2x-9

2x^3-18x

what is the rule for (fg)(x) for functions f(x)=2x^2-8 and g(x)=x+2
3x-6

3x²-10

2x²-x-10

x-10

The last choice 2x^3 - 18x.

Step-by-step explanation:

(fg)(x)  - f(x) * g(x)

= (x^2 - 9)(2x)

= 2x^3 - 18x.

did you get all 5 of these?

Step-by-step explanation:

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

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
