Answer:
My example:
1. Get the equation in the form y = ax4 + bx + c
2. Calculate -b / 4a. This is the x coordinate of the vertex
3. To find the y coordinate of the vertex, simply plug the value -b / 4a into the equation for x and solve for y.
Step-by-step explanation:
y=2x^2 -16x +30
vertex: ( 4, -2)
Focus: (4, -15/8)
Axis of symmetry: x = 4
Directrix: y = -17/8

Answer: Answer is 9
Step-by-step explanation:
Answer:
Step-by-step explanation:
1) they have same slope of 2 and are, therefore parallel.
Segment FG is on the line 2 x - y= -3
y = 2x + 3
Slope = 2
segment EH is on the line 2x - y = 1
-y = -2x +1
y = 2x - 1
Slope = 2
