Answer:
C) No, their slopes are not opposite reciprocals.
Step-by-step explanation:
First we find the slopes.
slope of PQ = (3 - 0)/(7 - 11) = 3/(-4) = -3/4
slope of RS = (-3 - 1)/(6 - 3) = -4/3
product of the slopes = (-3/4) * (-4/3) = 1
The slopes are reciprocals, but they are not opposite reciprocals, so the lines are not perpendicular.
Answer:
D. 5
Step-by-step explanation:
You can use proportions to solve this.
36/45=20/5x
Cross multiply the 5x and 36 as well as the 45 and 20
180x=900
Then, divide the 900 by 180
