The polynomial is a perfect square.
Answer:
(x, y) --> (y, x)
Step-by-step explanation:
Answer: x=5 y=6
Step-by-step explanation: 6y=3× +21
6y-6=2× +20
Opposite sides of the rectangle are equal
Substitute 3x +21 into 6y in the second equation.
Answer: Step-by-step explanation:
25y + 150x = 250 (÷25)
y+6x=10
y=10-6x
example x=1 y=4
The answer to 1/2y+3/2=3y+4 is y= -1
