Answer:
-1
Step-by-step explanation:
(0, 0) and (3, 3)
To find slope:
3-0/3-0 = 3/3 = 1
Since it's looking for the perpendicular slope, you just do the opposite of 1.
Which is -1.
Answer:
r=12
Step-by-step explanation:
Look, we can reverse the problem to get 23-11=r. This means that r=12.
Answer:
x = 1
Step-by-step explanation:
Subtract 10 from 8 to get -2. Then divide -2x by itself so it will cancel out. Whatever you do to one side of the equation, do to the other so divide -2 by -2 to get your answer of 1
250 calls in 10 hours = 375 in 15 hours
Answer:
90 yards in 15 minutes =6 yds/min
90 yards in 9 minutes =10 yds/min
x = current rate
r = rowing rate
r + x = 10
r - x = 6 Adding both equations
2 r = 16
rowing rate = 8 yds/min
x = 2 yds/min (current rate)
