Answer:
x=0, y=-5
Step-by-step explanation:
The system is
(1) 5x+3y=-15
(2) -8x-2y=10
Let's solve it by elimination. In order to do it, you have to multiply the equations by suitable numbers in such a way that when you add the 2 equations, one of the unknowns is eliminated
Multiply (1) by 2 and (2) by 3
(1) 10x+6y=-30
(2) -24x-6y=30
Add the two equations
10x-24x+6y-6y=-30+30 ----> -14x=0---->x=0
Now replace this value in any equation, for example in (1)
6y=-30 ----> y=-30/6----> y=-5

Answer:
Step-by-step explanation:
You need to use vertex form of a quadratic to solve this.
Consider the vertex to be 
Another way of representing a quadratic is in "vertex form":
Now all you have to do is solve for a. You know that the vertex is 
and you have know the point of 
. Now, all you have to do is plug in these values and solve for a.
Now you know the equation is 
, but you need it in quadratic form. All you have to do is solve is distribute the 6:
You get:
a = 6
b = 0
c = 2
