Step-by-step explanation:
(2590-2000) ÷ 2590 =
590 ÷ 2590 =
.2277 = 22.8%
X^2 - 7x = -12
2x - 7x = -12
-5x = - 12
x = 12/5
or
x = 2.4
Answer:
A
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-9)/(-3-2)
m=10/-5
m=-2
y=-2x+b
9=-2*-3+b
9=b+6
b=3
y=-2x+3
A
Answer:
Step-by-step explanation:
Calculate -b / 2a. This is the x-coordinate of the vertex.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
The standard form: ax^2 + bx + c
