Hey the answer is -0.2. You have to divide 10 by both sides to isolate the variable
Answer:
x=-15
Step-by-step explanation:
50=-10(x+10)
Distribute 10: 50=-10x-100
Add 100 to both sides: 100+50=-10x-100+100
150=-10x
Simplify: 150/-10=-10x/-10
x=-15
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
