Answer:
A square
36 square yard.
Step-by-step explanation:
Given the following information:
W(3,3), X(-3,3), Y(-3,-3), and Z(3,-3)
So we need to graph those vertices and connect them in order.
(please have a look at the attached photo)
From the graph, it clear that the shape of the garden is a square.
Then, we need to calculate the length of the four sides
<u>Find the length of the side YZ. </u>
The length of side YZ = 3 + 3 = 6 yards because point Y and Z are on the same line y = -3 so we just need to find the distance between their x coordinate
<u>Find the length of the side WZ.</u>
The length of side WZ = 3 + 3 = 6 yards because point W and Z are on the same line x = 3 so we just need to find the distance between their y coordinate
=> the area of the square WXYZ:
= YZ*WZ
= 6*6
= 36 square yard.
Answer:
(6, - 4 )
Step-by-step explanation:
Given the 2 equations
-
y = 3 → (1)
x -
= 12 → (2)
Multiply (1) by 8 and (2) by 6 to clear the fractions
2x - 3y = 24 → (3)
10x - 3y = 72 → (4)
Rearrange (3) expressing - 3y in terms of x by subtracting 2x from both sides
- 3y = 24 - 2x
Substitute 3y = 24 - 2x into (4)
10x + 24 - 2x = 72, that is
8x + 24 = 72 ( subtract 24 from both sides )
8x = 48 ( divide both sides by 8 )
x = 6
Substitute x = 6 in either (3) or (4) and solve for y
Substituting in (3)
2(6) - 3y = 24
12 - 3y = 24 ( subtract 12 from both sides )
- 3y = 12 ( divide both sides by - 3 )
y = - 4
Solution is (6, - 4 )
