Answer:
x + y = 2
y = 2 - x
so it is a linear equation.
2x + 5 = 11
2x = 11 - 5
2x = 6
x = 3
it is not a function because for just one <u>x</u> we have many <u>y</u>
Answer:
W (3 , 4) or W (3 . -4)
Step-by-step explanation:
W (3 , y), origin (0 ,0)
WO = √(3-0)²+(y-0)² = √9+y²
WO = 5
√9+y² = 5
9+y² = 25
y² = 16
y = ± 4
W (3 , 4) or W (3 . -4)
x=4 y=5
if we put two pharases together
the answer is as follows pic :
x=4 y=5
