1/3(x - 18) + 2/3x = 22

1/3x - 6 + 2/3x = 22

x - 6 = 22

x = 28

-2(-2x - 1) - (-3x - 6) = 10

4x + 2 + 3x + 6 = 10

7x + 8 = 10

7x = 2

x = 2/7

What is the slope? (8, 3) (-8, 3)

0

300

What is the rate of change? (-9, 3) (-9, 5)

Undefined

400

Is x = 4 a function?

No

500

Is this a linear function? y = 1/2(x - 6) + 5x - 10

EXPLAIN!!!

Yes, because it can be simplified into y=mx+b.

y= 1/2x - 3 + 5x - 10

y = 5.5x - 13

1/5(4x - 15) - 1/5x = 6/10x - 20

x = no solution!!!

4/5x - 3 - 1/5x = 6/10x - 20

3/5x - 3 = 3/5x - 20

-3 = -20
