The dimensions of the bulletin board is 2 ft and 9 ft.

Let the width of board = x

Then, the length of board = 7+x

Area of board = 18 ft²

Area of rectangle = L×W

so, (7+x) × x = 18 ft²

7x + x² = 18 ft²

7x + x² + 18 = 0

x² + 9x -2x -18 = 0

x(x+9) -2(x+9) = 0

(x+9) (x-2) = 0

x+9 =0, x -2 = 0

Dimension can not be in negative number, so

x = 2, Width = 2 ft

Length = 2+7 = 9 ft

Hence, the dimensions of board will be:

The width of board = 2 ft

And, the length of bard = 9 ft.

Which of the following is the graph of f(x) = –0.5|x + 3| –2?
oksano4ka [1.4K]

Answer:

See attached picture

Step-by-step explanation:

To graph an absolute value, find the vertex from f(x) = a|x-h|+k where (h,-k) is the vertex. Here (h,-k) is (-3, -2). Then test two points around it like x=-5 and -1.

f(x) = -0.5|-5+3|-2 = -0.5(2) -2 = -1-2 = -3

Plot (-5,-3).

f(x) = -0.5|-1+3|-2 = -0.5(2) -2 = -1-2 = -3

Plot (-1,-3).

Connect in V shape.
