Answer:

<em>#1:</em>

4x - 15 + 2x + 3 = 48\\\\2x + 18 = 48\\\\2x = 30\\\\x = 15

<em>#2:</em>

Part 1: Solve for x

6x - 7 = 5x + 1\\\\x - 7 = 1\\\\x = 8

Part 2: Plug in x for PQ

6(8) - 7\\\\48 - 7\\\\41

The length of segment PQ is 41.

Part 3: Plug in x for QR

5(8) + 1\\\\40 + 1\\\\41

The length of segment QR is 41.

Part 4: Length of PQ + length of QR = length of PR

PQ + QR = PR

41 + 41 = PR

82 = PR

The length of segment PR is 82.

Find the slope of the line that passes through G(−3, 2) and H(7, 2).
Svetllana [295]

Answer:

y=0x+2 meaning the slope is equal to 0

Step-by-step explanation:

If you think about this question you'll see that our two points have the same y coordinate

This means that the slope is equal to 0

so we have

y=0x+b  

If we plug in -3 for x and set the equation equal to 2 we can find b

0+b=2

b=2

so we have

0x+b=y

Hope this helps!
