According to the system:
5 – 7x + 2y² = -10
1 – 5x – 2y = -22
______________
a) No ; (4, 6) is not a solution to the
system. This point does not touch either equation.
b) No ; (6, 4) is not a solution to the system. This point does not touch either equation.
Solutions:

x = ( 122 ∓ 3√101 ) / 25 ≈ 3.674 or 6.086
y = ( -7 ± 3√101 ) / 10 ≈ 2.315 or -3.715
Answer:
1075 square feet.
Step-by-step explanation:
multiply 25 by 35 to get the big rectangle area, that's 875.
next the smaller rectangle area, 8 times 25. that's 200.
add em together and boom, 1075.
Answer: 47.5
Step by step:
5x+y (x=9)(y=2.5)
5(9)+2.5
45+2.5
= 47.5
Combine like terms
11x^2 - y
