No, if two lines are parallel then they will have NO solutions, because they DO NOT intersect. Parallel lines have the same slope and different y-intercepts, therefore making them not intersect.
Answer:
Step-by-step explanation:
Answer:
Fourth option is the correct one.
Step-by-step explanation:
Given:
Lets Assume
Now,
if we multiply both in sequence AB, we get
Now if we multiply both in sequence BA, we get
=
Hence AB ≠ BA
Now according to equation,
(A+B)² = A² + B² + AB + BA = A² + B² + 2AB only when AB = BA which is not the case as seen in example above
A.) graph of two lines that intersect at the point negative 1, 1, with text on graph that reads One Solution negative 1, 1
Step-by-step explanation:
The two simultaneous equation given are;
y+2x= -1
3y-x=4
multiply the first equation by 1 and the second equation by 2 to make the terms with x equal
y+2x = -1
6y-2x=8
-------------- ---add the terms with x to eliminate x
7y=7 -------divide both sides by 7 to remain with y
7y/7 =7/7
y= 1 -----use the value of y in the first equation
y+2x= -1
1+2x= -1
2x= -2
2x/2= -2/2
x= -1
The solution is (-1,1)
You can plot the equations on a graph tool as shown below to visualize the solution where the two linear equations intersect
