Sammie paid $15.16 less than the original price which is 40% of the original price. that means she got a 40% discount.

work:
37.90/2 is 50% of the price
$18.95 = 50%
divide that by 5 you get 10% of the price
$3.79 = 10%
multiply by 4 you'll get 40% of the price
$15.16 = 40%

Which equation represents a line which is parallel to the line 2x+y=-8?A. y=− 1/2 x−4B. y=−2x+5C. y=2x+3D. y= 1/2x+2

katrin2010 [14]

Two lines that are parallel have the same slope. In its slope-intersect form, we can write the equation of a line with slope m and y-intercept b as:

$y=mx+b$

Step 1

Write the given equation in slope-intercept form and identify its slope m.

$\begin{gathered} 2x+y=-8 \\ \\ 2x+y-2x=-2x-8 \\ \\ y=-2x-8 \end{gathered}$

Thus:

$m=-2$

Step 2

Find the equation with the same slope m = -2. We need to identify which of them has -2 multiplying the variable x.

Answer

From the given options, the only one with the same slope m = -2, therefore parallel to the given line, is:

$y=-2x+5\text{ (option B)}$
