Since the square is on a quadrant plane and it is a square, the fact that the lines cross in the center and start and stop in the corners allows you to tell that they are perpendicular.
So answer one is (B, D) 2 is (0, C) 3 is: 1
Answer:
-5
Step-by-step explanation:
x = first number
y = second number
From the first sentence
11 = 2x + 3y
From the second sentence (I'm assuming the word "dust" should be "first"
y = 2-x
rewritten as
x + y = 2
So your system of equations is
2x + 3y = 11
x + y = 2
Multiply the 2nd equation by -2
2x + 3y = 11
-2x - 2y = -4
Add the two equations together
y = 7
Use y=7 to solve for x
x = 2-y = 2-7 = -5

Answer:
x=.3
Step-by-step explanation:
3(x-2)=3x -2
(1x-2)=3(-1x)=3x -2
3(-1x)=3x -2
+3x +3x
3*2x=2
6x=2
6x/6=2/6
x=.3
