Answer:
It's the graph that its showed in the image
To find the answer of the first one, plug in numbers for x, and see if they make the inequality true. Like, 5, 6, and 7.
For the second one, add 13 to both sides. The answer is 21.
The area of Victoria's poster is twice the area of Krystal's poster.
<h3>How compare the areas of two similar posters</h3>
The two areas are shown in the image attached below. Each poster represents a rectangle and the ratio between the two areas (
), no unit, is defined by the following formula:
(1)
Where:
- Width of Victoria's poster, in feet.
- Height of Victoria's poster, in feet.
- Width of Krystal's poster, in feet.
- Height of Krystal's poster, in feet.
If we know that 
, 
, 
and 
, then the ratio between the two areas is:
The area of Victoria's poster is twice the area of Krystal's poster.

1 yard = 3 feet = 36 in
so 1 in = 1/36 yard, 1 ft = 1/3 yard.
The volume of the layer of the topsoil, is:
5 in * 23 ft * 17 ft = 5 *(1/36)*23*(1/3)*17*(1/3) yard cubed =
(5*23*17)/(36*3*3)= 1955/324=6.034 yard cubed.
The store only sells increments of 1/4 = 0.25 cubic yards.
we need 6.034/0.25=24.136
So we need to buy 25 (24 will not be enough) increments of 1/4 cubic yards.
Answer: 25 increments of 1/4 cubic yard, that is 25*0.25=6.25 cubic yards.
sin(θ) = ⁻⁴/₅
sin⁻¹[sin(θ)] = sin⁻¹(⁻⁴/₅)
θ ≈ -53.13
tan(θ) > 0
tan(53.13) > 0
1.33 > 0
