Answer:
Hey Xzavier! You're in my class!! Probably shouldn't use your real name on a cheating website... I mean ya... it's funny as hell and gave me a REALLY great laugh but our teachers know websites like these exist and by using your real name you're going to get caught eventually. I'm not a rat and I won't tell Mrs. Furnia but for future reference, use a screen name...
Step-by-step explanation:
Use subtitution method to solve the problem.
First, change y to the value of x in order to find the exact value of x.
x + y = 4
y = 4 - x
Second, subtitute y with 4 - x from the first equation
y = -x² + 2x + 4
4 - x = -x² + 2x + 4
move all terms to the left side
x² - 2x - x + 4 - 4 = 0
x² - 3x = 0
x(x - 3) = 0
x = 0 or x = 3
Third, now we have 2 values of x. Find the value of y for each of x
For x = 0
y = 4 - x
y = 4 - 0
y = 4
For x = 3
y = 4 - x
y = 4 - 3
y = 1
The solution is (0,4) and (3,1). The answer is option b

I don't think u can solve it with the full stop or decimal in between I can solve the problem for me if u type it without decimal point
