8-1 Quadratic Graphs and Their Properties How are the graphs of y 22 and y = - - 6x2 +1 similar? How are they different?
A. They have the same vertex, but they open in opposite directions.
B. They both open in the same direction, but the second graph is wider than the first graph.
о
C. They are both parabolas, but the second graph opens horizontally instead of vertically.
D. They have the same shape and axis of symmetry, but the second graph is shifted up 1 unit.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

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
