Answer: Yes
Step-by-step explanation:
x = 3
y = -7
10x + 20y ≥ -3
10 (3) + 20 (-7) ≥ -3
30 + (-140) ≥ -3
30 - 140 ≥ -3
-110 ≥ -3
(3, 7) is a solution

Answer:
7x^2 + 29xy -2y^2 + 8y
Step-by-step explanation:
3x(x+5y)+2y(7x-y)+4(x^2+2y)
Break all the brackets and you would hot:
= 3x*x + 3x*5y + 2y*7x - 2y*y + 4*x^2 + 4*2y
= 3x^2 + 15xy + 14xy -2y^2 + 4x^2 + 8y
= 3x^2 + 4x^2 +15xy + 14xy - 2y^2 + 8y
= 7x^2 + 29xy -2y^2 + 8y
Hope this help you :3
