Answer:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect
Answer:
t=-2
Step-by-step explanation:
(t+9)20=140
Distribute the 20
20t +180 = 140
Subtract 180 from each side
20t +180-180 = 140-180
20t = -40
Divide by 20
20t/20 = -40/20
t=-2
