Answer:
1. x = 4 and y = 1
2. x= 5 and y = 3
Use the examples below to complete 3 and 4.
Step-by-step explanation:
To solve each system of equations, use elimination.
1. Stack the equations and subtract to perform elimination.
2x + 2y = 10
- x + 2y = 6
-------------------------
x = 4
Substitute x = 4 into an equation to solve for y.
2(4) + 2y = 10
8 + 2y = 10
2y = 2
y = 1
2. Stack the equations and subtract to perform elimination.
3x + y = 18
- 2x + y = 13
-------------------------
x = 5
Substitute x = 5 into an equation to solve for y.
3(5) + y = 18
15 + y = 18
y = 3
Continue the same method for numbers 3 and 4.

Answer:
ac
Step-by-step explanation:
The length of the base is the x-distance between E and H, so is ...
base = a - 0 = a
The height is the y-distance between E and F, so is ...
height = c - 0 = c
The area of the parallelogram is the product of base and height.
A = base×height
A = a×c
The area of the parallelogram is ac.
