The answer is at 7:12 a.m, did you get that?
So there are two ways.
First you could solve for y and plug it into the calculator. one equation for y1 and another for y2. Then go 2nd trace and press 5 and then press enter 3 times to find the intersection.
the second way is to solve by hand. I would suggest solve the first equation for y and plug the equation solved for y into the other equation. so y = -3x + 9 and 3x-5y=15. Then you could do 3x - 5(-3x+9) = 15. Finally solve for x and plug in x into both equations to see if you get the same y value.
The answer should be (10/3, -1)
Step-by-step explanation:
x² - 2x - 48
= (x - 8)(x + 6)
Coefficient of x² is positive, => Happy shape curved upwards
Hence x < -6 or x > 8.
The answer is y=3x-4 and here are the steps
