Answer:To get the graph of the given parabola, we will use the equation of the parabola to check if given points in options are lying on that parabola or not. If they lie on the graph of parabola, then they would satisfy the equation, else not. We will use vertex form of parabola to get its vertex.
Thus, by below shown calculations, we have
Option A: On a coordinate plane, a parabola opens up. It goes through (-6, 0), has a vertex at (-2, -8), and goes through (2,0)
The answer is A.
I used the formula for finding the vertex of a parabola and I got the first answer choice. So A is correct. :)
Answer:
x = 7
y = -3
Step-by-step explanation:
x + y = 4 (Multiply this by 9)
-9x + 7y = -84
9x + 9y = 36
-9x + 7y = -84
16y = -48
y = -3
x + y = 4
x - 3 = 4
x = 7
