X/-5=-20<br><br> A -100 or 100<br> B -4 or 4<br> C 100<br> D no solution
alexgriva [62]

Move the negative sign to the left

-x/5 = -20

Multiply both sides by 5

-x = -20 × 5

Simplify 20 × 5 to 100

-x = -100

Multiply both sides by -1

<em>x = 100</em>

<u>C. 100</u>

Step 1:

First, let's order the number from least to greatest.

A. -0.31

B. -0.33

C. -0.38

D. -0.29

We could see that A, B, and C's numbers are already from least to greatest, so all we have to do is to move -0.29 (D) up to the top, since -0.29 is the number with the lowest value.

C. -0.38

B. -0.33

A. -0.31

D. -0.29

Step 2:

Let's look at the four number lines. Remember that we already organized the numbers from least to greatest, so the order they go in on the number line is: C, B, A, and D. Since Line C and D Don't follow that rule, we know those are not our answers. Also on line B, C is on the left of -0.4, but C's value is less than -0.4, so B is wrong. We are left with line A.

Line A: C. -0.38, B. -0.33, A. -0.31, D. -0.29

Our answer: Line A

Write the following equation in slope-intercept form 3x=-2y+4
Lorico [155]
The form is y=mx+b

3x=-2y+4 (add 2y)

3x+2y=4 (subtract 3x)

2y=-3x+4 (divide by 2)

y= -2/3x+2
