Answer:
YES
Step-by-step explanation:
Given the equations representing two lines:
2x - y = -3 ----› Equation 1
-6x - 2y = -6 -----› Equation 2
Multiply equation 1 by 2, and multiply equation 2 by 1.
2x - y = -3 ----› Equation 1 × 2
-6x - 2y = -6 -----› Equation 2 × 1
4x - 2y = -6
-6x - 2y = -6
Subtract both equations
10x = 0
Divide both sides by 10
x = 0/10
x = 0
Substitute x = 0 into equation 1
2x - y = -3
2(0) - y = -3
0 - y = -3
-y = -3
Divide both sides by -1
y = 3
Thus, the solution would be (0, 3).
It will not be parallel. To be parallel there needs to be a sum of 90 degrees, this will only add up to 87 :)
If you need area of the trapezoids:
Area of parallelogram = 10×7 = 70 sq. units
Area of each trapezoid = 1/2 × area of parallelogram = 1/2 × 70 = 35 sq. units
Answer:
3
Step-by-step explanation:
Answer:
D)
Step-by-step explanation:
x+y<-4
3x+2y= -5
3x+3y = -12
3x+2y= -5
0+y= -7
x+y= -4
x-7= -4
x= -4 + 7
x=3
=3,-7
