Answer:
see below
Step-by-step explanation:
The slopes of parallel lines are the same. The slopes of perpendicular lines are negative reciprocals of each other, hence their product is -1.
___
For the most part, the concept of adding slopes of lines does not relate to parallel or perpendicular lines in any way.
Answer:
m (x) = -2(x-6)^2 +18
Step-by-step explanation:
Answer:
x = 18
m<A = 166°
Step-by-step explanation:
The parallel lines are cut by a transversal, so corresponding angles A and B are congruent.
7x + 40 = 3x + 112
4x = 72
x = 18
m<A = 7x + 40 = 7(18) + 40 = 126 + 40 = 166
Answer:
7
Step-by-step explanation:
12-7=5
or
5+7=12
