What is the awnser of slope-intercept for 9x=3-3y

y = -3x + 1

Step-by-step explanation:

Rewrite 9x=3-3y in standard slope-intercept form.  Start by dividing all three terms by 3, obtaining

3x = 1 - y

We want to isolate y.   Adding y to both sides, we get y + 3x = 1.

Next, subtract 3x from both sides:  y = -3x + 1.

This result is in slope-intercept form; the slope is 3 and the y-int. is 1.  

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
