1) the vertex of a parable is given for two points, ( -b/2a, -b2-4ac/4a)
2) Now substitute the values in the equation
x = - (-8)/2(-2) = 8/ -4 = -2
y = -(8^2-4(-2)(1)/ 4(-2) = -(64-8) /-8 = 56/8 = 7
v(-2,7)

Hello,
As you write 1/x, x must be different of 0.
Answer:
10x+5y=120
y=-2x+24
Step-by-step explanation:
x=adult tickets
y=children tickets
120=total spent
10x+5y=120
5y=120-10x
y=(120/5)-(10x/5)
y=24-2x or y=-2x+24
-14
just multiply 2 on both sides to isolate x
