Answer:
x = 1, y = 4
Step-by-step explanation:
This is very simple
Since you have 2 equations with the same coefficient of x, just minus one equation from another:
x + 3y = 13
-
x + 2y = 9
1y = 4
Sub y = 4 into any of the 2 equation,
x + 3(4) = 13
x + 12 = 13
x = 13 - 12
= 1
Aos= -b/2a so plunin your numbers and you'll get the AOS so you can find the vertex
The first I think is 4 units square and the second is 21 units square
