The answer is x=-1.
•Multiply both sides by the Least Common Denominator:
2-4x=15+9x
•Subtract 2 from both sides:
-4x=15+9x−2
•Simplify 15+9x−2 to 9x+13:
-4x=9x+13
•Subtract 9x from both sides:
-13x=13
•Divide both sides by -13 and get your answer, x=-1.

Answer:
(C) 3 feet
Step-by-step explanation:
We have a function of f(x) here. When Sarina throws the ball, it has been 0 seconds since she threw it.
Since x represents the amount of seconds, we can find the height of the ball (f(x)) by substituting x in as 0.
0 squared is 0, 0 minus zero is 0, and 0+3 = 3, so
Meaning that when Sarina threw the ball, it's height was 3 feet.
Hope this helped!

Answer:
2x + 3y - 7
Step-by-step explanation:
3x − 2y − 7 + 5y − x =
2x - 2y - 7 + 5y =
