Q:
# Question Which ordered pairs are solutions to the equation 2x+10y=12? Select all that apply. Select all that apply: (7,−2) (−5,−4) (4,2/5) (−5,11/5)

Accepted Solution

A:

Answer:C and DStep-by-step explanation:To determine which pairs are solutions, substitute the coordinates into the left side of the equation and if equal to the right side then they are solutions.(7, - 2)2(7) + 10(- 2) = 14 - 20 = - 6 ≠ 12 → (7, - 2) is not a solution(- 5, - 4)2(- 5) + 10(- 4) = - 10 - 40 = - 50 ≠ 12 → (- 5, - 4) is not a solution(4, [tex]\frac{2}{5}[/tex] )2(4) + 10([tex]\frac{2}{5}[/tex]) = 8 + 4 = 12 → hence solution(- 5, [tex]\frac{11}{5}[/tex] )2(- 5) + 10( [tex]\frac{11}{5}[/tex]) = - 10 + 22 = 12 → hence solution
