Let a = x^2 and b=y^2
a-b=7
4a+b=73
4(7+b)+b=73 5b=45 b=9
a=7+b = 7+9 = 16
Then
x^2=16, x=+-4
y^2=9, y=+-3

Answer:
I would rather pay the 250 with the 25%
Step-by-step explanation:
I chose that one because it would be 187.50$ and the other one was 210$ (300 with 30% off) i got the final prices by doing 250•0.25=62.5 then 250-62.5=187.50 and for the second one 300•0.30=90 then 300-90=210.
What i did was find the percentage that was taken out of the original price to find the final price.
Answer:
Step-by-step explanation:
(-3, 5) and (4, -5)
(-5 - 5)/(4 + 3) = -10/7
y - 5 = 10/7(x + 3)
y - 5 = 10/7x + 30/7
y - 35/7 = 10/7x + 30/7
y = 10/7x + 65/7 is the equation
