x = 1, y = - 4

substitute y = - 4x into the other equation

x - 4x = - 3

- 3x = - 3 ( divide both sides by - 3 )

x = 1

substitute x = 1 into y = - 4x ⇒ y = - 4

Which equations are equivalent to Y=2/3X-4 when written in slope-intercept form? Check all that apply. A =3X-2Y=4. B=2X-3Y=12. C
shusha [124]

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

The standard form: Ax + By = C.

We have:

y=\dfrac{2}{3}x-4       <em>multiply both sides by 3</em>

3y=2x-12     <em>subtract 2x from both sides</em>

-2x+3y=-12       <em>change the signs</em>

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

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

<h3>Answer: B and C.</h3>

A. 3x - 2y = 4   - NOT

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

E. 2x - 3y = 4    - NOT

Asia uses an overhead projector to enlarge a drawing. The original drawing measures 75 cm wide by 100 cm high. She moves the pro

You can find the scale factor by dividing the final dimension by the initial dimension

\frac{375}{75}, which can be simplified to \frac{5}{1} or 5.

You then multiply the other dimension, the width, by the scale factor to find the width of the enlarged projection.

100 x 5 = 500 cm
