Answer:
y=1
Step-by-step explanation:
5y(2x-1)=y(x+2)+20, x=3
5y(2(3)-1)=y(3+2)+20
5y(6-1)=y(5)+20
5y(5)=5y+20
25y=5y+20
25y-5y=20
20y=20
y=20/20
y=1

Answer:

Vertex = (8, -8)
Step-by-step explanation:
<u>Standard form</u>: 
<u>Vertex form</u>: 
where (h, k) is the vertex
<u>Intercept form</u>: 
where p and q are the x-intercepts
Therefore, the form that most quickly reveals the vertex is

The vertex is (8, -8)
