Step-by-step explanation:
Y - 4 x = 7 - x²
y = - x ² + 4 x + 7 ( this is a quadratic function )
x = - b / 2 a, where: a = - 1 and b = 4
x = - 4 / ( - 2 ) = 2
Answer:
The axis of symmetry for the graph is x = 2
Answer:
308629.44
Step-by-step explanation:
380 = c + h
c = cheeseburgers
h = hamburgers
c = h - 70
380 = (h - 70) + h
So, fire we are going to add 70 to both sides.
450 = 2h
Divide by 2
225 = h
Hamburgers = 225
Cheese burgers = 225 - 70 = 155
380 = 155 + 225
There were 225 hamburgers sold on Wednesday.
Answer:
The correct solution is C (x> -2)
