Answer:
Step-by-step explanation:
The relationship is linear, so the plant grows the same amount each day.
The height on the 2nd day was 8 inches:
h₂ = 8
The height on the 7th day was 20.5 inches:
h₇ = h₂ + (7-2)d = 8 + 5d = 20.5
d = 2.5
The plant grows 2.5 inches each day.

First subtract 9 from both sides of the equation.
-x - 9

+9 +9
-x

Then divide -1 on both sides.
-x/-1

I'm pretty sure when you divide a negative number when solving inequalities, you switch the sign.
