Best ResponseYou've already chosen the best response.0y=x^2+3 y=x+5 We can do this x^2 + 3 = x + 5 x^2  x + 3  5 = 0 x^2  x  2 = 0 Now , solve this equation for x .

Best ResponseYou've already chosen the best response.0(x2)(x+1) = 0 X2 = 0 or x + 1 = 0 so x is either 1 or 2

Best ResponseYou've already chosen the best response.0i don't know. it's not a multiple choice question :/ it just say solve the system of equations

phi

Best ResponseYou've already chosen the best response.0x= 1 or x=2 use those numbers to find the corresponding y in y=x+5

phi

Best ResponseYou've already chosen the best response.0this problem has two solutions i.e. two (x,y) points that lie on both the line and the parabola.

Best ResponseYou've already chosen the best response.0so it doesn't matter which x i use ?

Best ResponseYou've already chosen the best response.0you use both, one at a time. you want to find two (x,y) pairs where x is 1 in the first pair (and you need to find the y) and x=2 in the other pair

Best ResponseYou've already chosen the best response.0so it would be (1,4) or (2,7)

Best ResponseYou've already chosen the best response.0what do i do about the other y equation?

phi

Best ResponseYou've already chosen the best response.0you could use either equation to find y but it makes sense to use the easier one. you are done! btw, here is what you found... where the line meets the parabola
