Identifying an Error A student simplified a rational expression as
shown.
20 522
x2 + x 6
5(4-22)
( - 2) 0 + 3)
5(2-2) (2 + x)
(-2)(x + 3)
5(x + 2)
(x + 3)
Which of the following mistakes did the student
make?
The Student did not factor the numerator
correctly.
The student could not divide out (2-x) and
(x - 2) as written.
The student did not factor the denominator
correctly.
The student needed to simplify further by
dividing out x.
DONE

thats not a system of equations, that is a solution

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
