A squirrel throws an acorn from the top of an 18 foot tall tree. The acorn reachega height of 18.36 feet above the ground after 0.2 seconds and a height of 7 feet above the ground after 1 second.
1. Identify the independent and dependent variables.
Independent Variable:
Dependent Variable:

4y - 6 + y^2 - 9 = y^2 + 4y - 15y^2 term terms- termstotal of 3 terms when simplified

1. use commutative property to reorder the terms.2x+81=0.2. move the constant to right side by adding its opposite on both sides. 2x+81-81=0-81.2x=(-81).3. divide the equation on both sides.2x ÷ 2 = 81 ÷ 2.x = -81/2. your answer is -81/2. if you need to simplify it into a decimal, it’s -40.5.
