Answer:
x ≥ −5 and x < 4
Step-by-step explanation:
-4x + 1 ≤ 21 and 5x + 2 < 22
5x + 2 < 22 =<u> x < 4</u>
We can plug it in: 5 x 3 + 2 < 22 = <u>17 < 22</u>
-4x + 1 ≤ 21 = x= -5 and lower
Plug it in: -4 x -5 + 1 ≤ 21 = 21 ≤ 21 = <u>x ≥−5</u>
So both answers would be:
x ≥−5 for -4x + 1 ≥ 21
x < 4 for 5x + 2 < 22

Answer: A) Use the distance formula to find the length of each side, then add the side lengths</h3>
The perimeter is simply the distance around the outer edge of the figure, which is why we add up the four sides. The distance between points A and B is the same as the length of segment AB. You can use the pythagorean theorem to find the distance, but you'll need to draw in the right triangles. Effectively the distance formula is the pythagorean theorem, but using coordinate geometry.
