A storage shelf can hold no more than 250 pounds. Carlos wants to stack boxes of paper that weigh 20 pounds each and computer monitors that weigh 15 pounds each on the shelf. a. Write an inequality that shows how many boxes of paper, x, and monitors y, Carlos can stack on the shelf. b. Give 3 examples of paper and monitor combinations that Carlos can stack on the shelf.

a) The inequality function is 20x + 15y< 250

b) The 3 examples are (x,y): (1,1) (2,3) (11,2)

Given that,

Based on the above information, the calculation is as follows:

20x + 15y is less than or equal to 250

Three examples:  (1,1) , (2,3) , (11,2)

a) 20x + 15y 《 250

b) (x,y): (1,1) (2,3) (11,2)

Step-by-step explanation:

20x + 15y is less than/equal to 250

There are many combinations of x and y that satisfies this inequality.

Three examples:

(1,1)

(2,3)

(11,2)

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
