Answer:

y = 1/2x^2 - 2x + 1

Step-by-step explanation:

The equation of the parabola in vertex form is y = 1/2 (x - 2)^2 - 1. By finding the vertex at (2,-1) we plug in the point into the formula y = a(x-h)^2 + k. To convert it to standard form like the equations listed, multiply through the distributive property to clear the parenthesis.

y = 1/2 (x-2)(x-2) - 1

y = 1/2 (x^2 - 4x + 4) - 1

y = 1/2x^2 - 2x + 2 - 1

y = 1/2x^2 - 2x + 1

3x+1y=6 2x-1y=-1 plz helpllllllllll
Gwar [14]

Answer:

x=1 y=3

Step-by-step explanation:

3x+y=6 is the same as y=6-3x

2x-y=-1 is the same as y=2x+1

set them equal to each other

6-3x=2x+1

5x=5

x=1

substitute the value of x into either equation

y=2(1) +1

y=3
