Step-by-step explanation:
You need to find the prime factors of each term in order to find the greatest common factor.
The answer is 3.
Answer:
a) (11/7, 9/7)
b) There's no point of intersection
Step-by-step explanation:
a) x - 2y + 1 = 0
2x + 3y - 7 = 0
To find the point of intersection, we need to solve the system of equations and the result will be the point of intersection (x,y)

Now we substitute x in the second equation:

Now we substitute y in our first equation.
.
The point of intersection is (11/7, 9/7)
b) x -2y +11 =0
-x + 2y - 13 =0
We are going to follow the same procedure:


Since this system of equations doesn't have a solution, the system has no point of intersection.
Answer: A and B only
Step-by-step explanation:
In function, for one value of x there must be only one value of y.
x=-26 is the final anwser :)
