The solution is, x=8, y=-7
Answer: answer A
Step-by-step explanation:
Solve the equation systems or set the values x = 1.8 and y = -0.9 on the equation and check the equality.
A.
6x - 5y = 15
L = 6(1.8) - 5(-0.9) = 10.8 + 4.5 = 15.3
R = 15
L ≈ R
x + 2y = 0
L = 1.8 + 2(-0.9) = 1.8 - 1.8 = 0
L = R
B.
4x + 5y = 8
L = 4(1.8) + 5(-0.9) = 7.2 - 4.5 = 2.7
R = 8
L ≠ R
C.
x - 2y = 4
L = 1.8 - 2(-0.9) = 1.8 + 1.8 = 3.6
R = 4
L ≈ R
4x + 5y = 8
L = 4(1.8) + 5(-0.9) = 7.2 - 4.5 = 2.7
R = 8
L ≠ R
D.
6x - 5y = 15
L = 6(1.8) - 5(-0.9) = 10.8 + 4.5 = 15.3
R = 15
L ≈ R
x - 2y = 4
L = 1.8 - 2(-0.9) = 1.8 + 1.8 = 3.6
R = 4
L ≈ R
We have two probability solutions: A and D.
But I think, Your answer is A.
Answer:A, D, E
Step-by-step explanation:
Slope equals change in y divided by change in x.
m=(y2-y1)/(x2-x1)
m=(1-1)/(5--3)
m=0/8
m=0
The slope is zero.
So this is a horizontal line of the form y=1
