Solve for each system of equations by substitution or elimination. 1.y=x^2+5x+1y=x^2+2x+12. y=x^2-2x-1y= -x^2-2x-13. y=x^2+2x+1y=x^2+2x-1

QUESTION 1

The given system of equations are:

We equate the two equations to get:

When x=0,

The solution is (0,1)

QUESTION 2

The given equations are:

and

We equate both equations to get:

Group similar terms,

We put x=0 into any of the equations to find y.

The solution is (0,-1).

QUESTION 3

The given equations are:

and

We equate both equations:

Group similar terms:

This is not true.

Hence the system has no solution.

lol we need to see what the question is asking about
