Which iequailty model and solution set best represents the possible side lengths of miriam's bulletin board?

faltersainse [42]

Question:

Miriam is making a bulletin board that is shaped like a square. She has 72 inches of border material. If x represents the length of one side of the bulletin board, which inequality model and solution set best represents the possible side lengths of Miriam's bulletin board?

Answer:

$x \le 18$

Step-by-step explanation:

Given

$Border\ Material = 72$

Required

Determine an inequality for x

Represent the side lengths of the border with y. So:

Since the border is on the 4 sides, then

$4y = 72$ -- i.e. the perimeter of the border material

Solve for y

$y =\frac{72}{4}$

$y =18$

Recall that x represents the board's side length.

Since x will be situated inside the boarder, then.

$x \le y$

Substitute $y =18$

$x \le 18$

The endpoints of CD are C(1, -6)and D(7,5). Find the coordinate of the midpoint, M

yuradex [85]

Answer:

(4, - 0.5 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ $\frac{x_{1}+x_{2} }{2}$ , $\frac{y_{1}+y_{2} }{2}$ ]

Here (x₁, y₁ ) = C(1, - 6) and (x₂, y₂ ) = D(7, 5) , then

midpoint = ( $\frac{1+7}{2}$ , $\frac{-6+5}{2}$ ) = $\frac{8}{2}$ , $\frac{-1}{2}$ ) = (4, - 0.5 )
