Answer:
x = 1/4(y -4)² +7
Step-by-step explanation:
A parabola can have the equation ...
x = 1/(4p)(y -k)² +h
where the vertex is (h, k), and the vertex-to-focus distance is p.
The vertex is halfway between the focus and directrix, so has coordinates ...
((8, 4) +(6, 4))/2 = (7, 4)
The distance from the vertex to the focus is 8-7 = 1, so the equation can be written ...
x = 1/4(y -4)² +7

Answer:
2a-9=2a-9
<em>Infinitely Many Solutions</em>
Step-by-step explanation:
2(a-8)+7=5(a+2)-3a-19
<em>Use Distributive Property</em>
2a-16+7=5a+10-3a-19
<em>Combine Like Terms</em>
2a-9=2a-9
