Let f(x) = -2x + 4 and g(x) = -6x - 7. Find f(x) - g(x). can anybody help me with this? show your work if you can too, please!

  f(x) -g(x) = 4x +11

Step-by-step explanation:

Substitute the given expressions and simplify.

  f(x) -g(x) = (-2x+4) -(-6x-7)

Eliminating parentheses, we get ...

  f(x) -g(x) = -2x +4 +6x +7 = (-2+6)x +(4 +7) . . . . combining like terms

  f(x) -g(x) = 4x +11

linear pair postulates

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
