Which ordered pair is a solution to the equation 2x - 4y = 18?
(-1, 4)
(0, 4)
(9, 2)
(11, 1)

 The correct option is (D) (11, 1).

Step-by-step explanation:  We are given to select the correct ordered pair that is a solution to the following equation :

If an ordered par is a solution to the given equation (i), it must satisfy the equation.

(A) (-1, 4).

For x = -1  and  y = 4, we have

So, the ordered pair (-1, 4) is NOT a solution to equation (i).

(B) (0, 4).

For x = 0  and  y = 4, we have

So, the ordered pair (0, 4) is NOT a solution to equation (i).

(C) (9, 2).

For x = 9  and  y = 2, we have

So, the ordered pair (9, 2) is NOT a solution to equation (i).

(D) (11, 1).

For x = 11  and  y = 1, we have

So, the ordered pair (11, 1) is a solution to equation (i).

Thus, the correct option is (D).

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
