Answer:

Step-by-step explanation:

The standard equation for a parabola is y = ax^2 + bx + c. If the coefficient a is positive, then the curve (graph) opens up.

In y=x^2+2x+8 this coefficient is +1, so the curve opens up.

Solve the following system of equations:

grin007 [14]

A) 4x − 2y − z = −5
B) x − 3y + 2z = 3
C) 3x + y − 2z = −5
Looking at ALL 4 solutions, x =0 in all of them.
So, let's say x = 0, eliminate the "x's" and just keep equations B and C

B) -3y + 2z = 3
C) y − 2z = −5
Add B) and C)
-2 y = -2
y = 1

1 − 2z = −5
-2z = -6

z = 3

and x = 0
