Answer from: alex6toes

The slope-intercept form: y = mx + b.

The standard form: Ax + By = C.

We have:

$y=\dfrac{2}{3}x-4$ multiply both sides by 3

3y=2x-12 subtract 2x from both sides

-2x+3y=-12 change the signs

$2x-3y=12\to\boxed{B.}$ multiply both sides by (-4)

$-4(2x-3y)=-4(12)\to\boxed{C.}$

B and C.

A. 3x - 2y = 4 - NOT

D. 2(x + 6) = 3y → 2x + 12 = 3y → 2x - 3y = -12 - NOT

E. 2x - 3y = 4 - NOT

Answer from: mirandac6775

B 2X-3Y=12

C -4(2X-3Y)=-4(12)

Step-by-step explanation:

y = 2/3 x -4

multiply by 3

3y = 2x -12 factor out a 2 3y = 2(x-6)

subtract 2x from each side

-2x+3y = -12

multiply by -1

2x-3y = 12

multiply by -4

-4(2x-3y) = -4(12)

in the opening of the question the word 'service' is associated only with the pretax value.

the closing part of the question asks: how much did she pay for the

service

−−−−−−

so technically the answer is

→

72.6

(

87.12

however, the intention of the question provider may have been that your answer is to be

)

94.09

to 2 decimal places.
