Consider the given function:

From the linear function, 210 is the height of the tree from when Renata moved to her new home, and 33 states that the tree grows 33 cm per year.
So "How fast does the tree grow?"
The tree grows 33 cm per year.
-2w + 20 = -17 - 17 + 4w
Combine like terms on the right side of the equation.
-2w + 20 = -34 + 4w
Add 2w to both sides.
20 = -34 + 6w
Add 34 to both sides.
54 = 6w
Divide both sides by 6.
w = 9 is your answer.
The 21 part repeats
it can be represented as 21/99
it's rational
Answer:
x=-18
Step-by-step explanation:
multiply the invisible 1 outside the parenthesis with the numbers inside. next combine like terms on the left side of the equation. then simplify the equation. then divide -2x by -36. then multiply -1 to your answer and the outcome gives -18
