Answer:

(9/4, 3/4)

Explanation:

4x + 4y = 12
2(-2x + y = -3)

4x + 4y = 12
-4x + 4y = -6

8y = 6

y = 3/4

4x + 4(3/4) = 12

4x + 3 = 12

4x = 9

$s\geq 23$

Step-by-step explanation:

We are given that a student needs to make a square cardboard piece.

Perimeter of cardboard should be equal to atleast 92 inches

We have to find that which shows reasonable domain for f(s)

Let s be the side of square cardboard

We know that perimeter of square =f(s=) $4\times side$

Then, perimeter of cardboard= $4s$

$4s\geq 92$

Dividing by 4 on both sides

$s\geq 23$

Hence, the domain of function $[23,\infty)$

Therefore, option d is true.

Answer:d: $s\geq 23$
