Question

Solve the following system of equations and show all work.

y = x2 + 3
y = x + 5

Answer 1

Is it x^2?

Answer 2

yep!

Answer 3

Okay lets use substitution method here... Substitute the second equation in first,

So,
x^2+3=x+5
x^2-x-2=0
Can you solve for x?

Answer 4

2,-1

Answer 5

Perfect Now substitute the values for x and find the corresponding y values :)

Answer 6

Not sure how to do that hahaha

Answer 7

I will help you :)
Take any one equation...
Let us take the linear one cause you know... quadratic is tougher than linear...

y=x+5

so when x=2... y=2+5=7 So the solution pair is (2,7)
Similarly find for x=-1 and thats your answer set :)

Answer 8

2^2-1-2?

Answer 9

Why did you go for the quadratic?? Use the same linear function no?

Answer 10

y=x+5
what is y when x=-1?

Answer 11

2 I think

Answer 12

How ? O_o
y=-1+5

Answer 13

oh hahaha no it's 4

Answer 14

Yes, so the answer set is (-1,4) and (2,7). Cheers Mate :)
