Answer:

D.(1,1)

Step-by-step explanation:

Just plug in each pair of values in the multiple choice answers for x and y.

If we plug in (1,1)

The equation is

4(1) +5(1) ≤ 20

4+5≤ 20

9≤ 20

Since 9 is less than 20 we know statement is true, so we know (1,1) is a solution.

If we were to plug in any other choice like (0,5), the right side of the equation would be greater than 20 and the statement would not be true.
