Seems all good to me at least!
Answer:
4
Step-by-step explanation:
= 4 because the variable y on the numerator and the denominator can cancel out.
Answer: Linear
Step-by-step explanation:
Linear means that in an equation, the highest power of x is 1. Or, there are no x^2, x^3, etc. Only x^1. Quadratic means that the highest power of x is 2. This is also called the degree. The degree is the highest power of x.
a. 15.6 (78/5)
b. I think it would be 12.48
Y = -2x² + 8x - 18
x = -b/2a
x = -8/2(-2)
x = -8/-4
x = 2
y = -2x² + 8x - 18
y = -2(2)² + 8(2) - 18
y = -2(4) + 16 - 18
y = -8 - 2
y = -10
(x, y) = (2, -10)
Vertex: (2, -10)
Axis of Symmetry: x = 2
