Answer:

6, but the question makes more sense when asking about 12.5% from 48

Step-by-step explanation:

to get a percentage of something, we just have to remember that $X\% = \frac{X}{100}$ and that we just need to multiply.

Yes, percentages are just numbers, but the percentage sign lets us signify the purpose of a number.

48 * 12.5% = 48 * 0.125 = 48 / 8 = 6

y = −2x + 13

y = 2x − 3

Set the equations to equal and solve for x:

-2x + 13 = 2x -3

Add 2X to each side:

13 = 4x -3

Add 3 to each side:

16 = 4x

Divide both sides by 4:

x = 16/4

x = 4

Now replace x with 4 in one of the equations and solve for y:

y = -2(4) +13

y = -8 +13

y = 5

x = 4 and y = 5 , which is the ordered pair (4,5)

Both numbers are positive values, so the second graph is correct.

-2 3/4 ÷ -1/7= <br>help

Hitman42 [59]

The answer is 19 $\frac{1}{4}$

First you must set up the equation

$-2\frac{3}{4}$ ÷ $-\frac{1}{7}$

First, you must make the mixed number a improper fraction

$-\frac{11}{4}$ ÷ $-\frac{1}{7}$

Then you must divide

$\frac{77}{4}$

Finally, simplify

19 $\frac{1}{4}$

Through: (4, -3), perp. to y=-2x + 1

larisa86 [58]

Step-by-step explanation:

y = -2x + 1. => Slope = -2

Then the perpendicular line will have a slope of -1/(-2) = 0.5.

We have y = 0.5x + c.

When x = 4, y = -3.

=> (-3) = 0.5(4) + c, c = -5.

Hence the answer is y = 0.5x - 5. (C)
