Answer:
Step-by-step explanation:
If 
, then 
and are alternate interior angles.
This means that line segment AC is a transversal.
This implies that line segment AD is parallel to line segment BC.
The second choice is the correct answer.
I thinks it’s A because I did this before
Answer:
Line m is not parallel to Line n.
Line m is perpendicular to Line k
Step-by-step explanation:
1. Calculate slopes of n and m. N = -2 and M = -7/4. The two slopes aren't the same thus they are not parallel
2. Slope of m = -7/4 and k = 4/7. By definition of perpendicular these two fit the description. (to be perpendicular, k = -1/m
Answer:
x<-3 or x>2, 2<x<-3
Step-by-step explanation:
Subtract/add from each side then divide, if dividing by a negative reverse the sign.
Answer:
x = 0,3
Step-by-step explanation:
y-10x=5 move -10x to the other side to get y by itself
y=10x+5 then you would substitute this equation into the other equation where you see y
10x+5=x^2+7x+5 move everything to one side
0=x^2+7x+5-10x-5 combine like terms
0=x^2-3x factor
0 = x(x-3) set each equal to zero
x=0
x-3 = 0 add 3 to both sides
x = 3
the answer is x=0 and x=3
