Answer:
7x² - 3x - 4
Step-by-step explanation:
<u>Step 1: Write expression</u>
(6x² - x + 3) + (-2x + x² - 7)
<u>Step 2: Combine like terms (x²)</u>
7x² - x + 3 - 2x - 7
<u>Step 3: Combine like terms (x)</u>
7x² - 3x + 3 - 7
<u>Step 4: Combine like terms (constants)</u>
7x² - 3x - 4
Answer:
A
Step-by-step explanation:
-When the function moves to the right or left to the x axis, the number has to be in "( )"
-If it moves to the right, you SUBTRACT the amount of units
-It it moves to the left, you ADD the amount of units.
So in this case, it is moving to the right 12 units so it is
