Step-by-step explanation:
I hope this is good :)
Step-by-step explanation:
m
one set of ordered pair
b
Answer:
Step-by-step explanation:
Number 13:
a+b=3+4
= 7
Number 14:
c-a= 12-3
= 9
Number 15:
a+b+c= 3+4+12
= 19
A) x + y = 24
B) x^2 + y^2 = 306
A) x = 24 -y
Then substituting this into B)
(24 - y)^2 +y^2 = 306
576 -48y +y^2 + y^2 = 306
2 y^2 -48y + 270 = 0
x1 = 15
x2 = 9
