Answer:
Step-by-step explanation:
Vertex form of a quadratic function:
where:
- (h, k) is the vertex
- a is some constant
If the vertex is at the origin, then (h, k) = (0, 0)
Comparing this with the answer options suggests that the function with a vertex at the origin is
5 x + 3 y = 41 / * 3
3 x + 2 y = 26 / * ( - 5 )
-----------------------------
15 x + 9 y = 123
+
- 15 x - 10 y = - 130
---------------------------
- y = - 7 / * ( - 1 )
y = 7

You can turn 9/6 into a mixed number by doing it 2 ways:
9/6=1 3/6 or 1 1/2
<span>Or you can simplify it to 3/2 to make it easier to form into a mixed number. 1 1/2
Hope this helped :)</span>
