Q:

Which y-values make the ordered pair (5 ,y) a solution of the following inequality?-7x+5y≥5

Accepted Solution

A:
Answer:For   x= 5 and  all values of  y ≥ 8 , the above inequality holds TRUE.Step-by-step explanation:Here, the given inequality is:-7x + 5y ≥ 5Now, for (5,y) to be the solution of  above equation, Left side of equation at (5,0) should be  greater than equal to 5.Now, -7x + 5y  =  -7 ( 5) + 5 y = -35 + 5 yAlso, Left side is greater than equal to 5⇒ -35 + 5 y   ≥ 5or, -35 + 5 y   + 35  ≥ 5   + 35or, 5 y ≥  40or, y ≥ 40/ 5 = 8or , y ≥ 8Hence, for all values of  x= 5 and  y ≥ 8 , the above inequality holds TRUE.
