Best ResponseYou've already chosen the best response.0Since y =x+5 you could plug that into the first equation: \(\large y=\color{green}{x^2+3} \) \(\large y=\color{red}{x+5}\) \(\Large \color{red}{x+5}=\color{green}{x^2+3}\) Now solve

Best ResponseYou've already chosen the best response.1so you are looking for the points of intersection, so you can equate them \[x + 5 = x^2 + 3\] if you rewrite the equation you get \[x^2  x  2 = 0\] this can be solved by factoring

Best ResponseYou've already chosen the best response.1when you get the solutions for x, substitute them into either equation to find the corresponding y values... remember the solutions are points (x,y)
