Hello :
<span>2x - y - 4 = 0 ....(1)
3x + y - 9 = 0 ....(2)
(1)+(2) : 5x-13 =0
5x=13
x=13/5
subsct in (2) :3(13/5)+y-9=0
y = 9-39/5
y=6/5
answer : </span><span>b. {(13/5, 6/5)}</span>

Answer:
(a) y=(x+4)^2 +7
Step-by-step explanation:
The vertex form equation is ...
y = a(x -h)^2 +k
for vertex (h, k) and vertical scale factor 'a'.
The vertex is given as (h, k) = (-4, 7), so the equation will be ...
y = a(x +4)^2 +7
The value of 'a' can be found from the other given point:
8 = a(-3+4)^2 +7
1 = a
So, the equation is ...
y = (x +4)^2 +7
