Please read explanation below.
Step-by-step explanation:
Let's go over what some of the symbols of inequalities represent:
: greater than
: less than
: greater than or equal to
: less than or equal to
The symbol in the equation that is given to you is . It seems as though each of the answer choices have everything written as the same thing except for the description of the inequalities. Check the one that applies.

Answer:
people cant mark you brainlest but you can mark people who answer your questions brainliest
Step-by-step explanation:
(Sorry if I get something wrong, it’s straining my eyes to see what letter) 1. A 2. U 3. S 4. J 5. I 6. M 7. H 8. B 9. Y 10. L
To find where a coordinate is on a graph you need to start with the first number (x) (let’s say the coordinate is (2, -3), so 2) and find where it is ( you always find where the first number is on the x-axis and the second number on the y, remember that by x, y and x comes first.) Then, you need to find the second number (-3) then you need to find where they meet. So 2, -3 is on the letter I.
To find what coordinates a point that’s already been plotted is to see, for example, L, the two numbers that meet where L is are -4, -3, remember whatever was on the x axis comes first, -3, -4 is not the same.
Hopefully this makes sense, I don’t normally answer stuff.
Answer:
Part 1) The shape is a trapezoid
Part 2) The perimeter is 
or approximately 
Part 3) The area is 
Step-by-step explanation:
step 1
Plot the figure to better understand the problem
we have
A(-28,2),B(-21,-22),C(27,-8),D(-4,9)
using a graphing tool
The shape is a trapezoid
see the attached figure
step 2
Find the perimeter
we know that
The perimeter of the trapezoid is equal to
the formula to calculate the distance between two points is equal to
Find the distance AB
we have
A(-28,2),B(-21,-22)
substitute in the formula
Find the distance BC
we have
B(-21,-22),C(27,-8)
substitute in the formula
Find the distance CD
we have
C(27,-8),D(-4,9)
substitute in the formula
Find the distance AD
we have
A(-28,2),D(-4,9)
substitute in the formula
Find the perimeter
simplify
----> exact value
therefore
The perimeter is or approximately
step 3
Find the area
The area of trapezoid is equal to
![A=\frac{1}{2}[BC+AD]AB](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5BBC%2BAD%5DAB)
substitute the given values
![A=\frac{1}{2}[50+25]25=937.5\ units^2](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5B50%2B25%5D25%3D937.5%5C%20units%5E2)
