Select the correct answer from the drop-down menu. the solution set for -2x2 + 12x = 0 is .? {0, 12} {0, -12} {0, 6} {0, -6}

Fourth is correct option, {0, -6}.

Solution:

Equation:

-2x2 + 12x = 0

= x(-2x + 12) = 0

= x= 0                                       ,     -2x + 12 = 0

                                                           -2x =-12

                                                               x = -12/-2

                                                                x = -6

                                          Solution set = {0, -6}

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
