Which of the following is a solution of 4x + 5y ≤ 20? a. (5, 7) b. (1, 1) c. (0, 5) d. (8, 0)

For this case we must replace each of the points and verify if the inequality is met:

Point: (5,7)

It is not fulfilled!

Point: (1,1)

Is fulfilled!

Point: (0,5)

It is not fulfilled!

Point: (8,0)

It is not fulfilled!

(1,1)

B.

Step-by-step explanation:

Plug in and see:

Let's try the first (x,y)=(5,7)

4(5)+5(7) <=20

20+35<=20 not true so not A

Let's try (1,1) for (x,y)

4(1)+5(1)<=20

4+5<=20 that is true so choice B looks good

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

if you divide 9 by 6 you will get 54.
