Question

@midhun.madhu1987 Please Help!

Answer 1

Create a system of equations that includes one linear equation and one quadratic equation.
f(x) = 2x + 1
y = x2 + x - 2
Part 1. Show all work to solving your system of equations algebraically.
Part 2. Graph your system of equations, and show the solution graphically to verify your solution.


I created the two equations I believe I can use, but I am unsure of how to do the two other requirements.

Answer 2

I think this is the way...

Answer 3

The general form of a Linear Equation is:

ax + by + c = 0

and that of a Quadratic Equation is:

ax^2 + bx + c = 0

Example: x + y = 2(Linear Equation) ---------- (1)

x^2 + 2x + 3 = 0 (Quadratic Equation) --------(2)

From (1), x = 2 - y

Substitute this value of x in equation (2) and solve for y.

Answer 4

Thanks. Sorry I walked away from the computer for a minute.

Answer 5

Thats okay .. :)

Answer 6

So what would be an example of a linear equation. I saw the variable version of it you wrote (ax+by+c=0) but what is a numerical version of this?

Answer 7

@midhun.madhu1987

Answer 8

i also gave examples also.. equation (1) is a linear equation

Answer 9

Oh okay I didn't see that. My apologies. Would those be suitable equations to use for this question?

Answer 10

i guess so... u can just check it out

Answer 11

@midhun.madhu1987 Can you tell me what the ordered pair would be for these solved? x+y=2
x^2+2x+3=0
