Answer:
y=-3x+5
Step-by-step explanation:
y=-3x-7
slope is -3
parallel lines have the same steepness, they have the same slope. The slopes are equal.
y-y1=m(x-x1)
y-2=-3(x-1)
y-2=-3x+3
y=-3x+3+2
y=-3x+5
5) x=-4
6)p=8
7) x=40
8) a=5
9) b=16
10) q=2
Adam's average speed = 40 miles per hr
time for the trip = 30 minutes = 0.5 hrs
Distance travelled by adam = speed * time = 40 * 0.5 = 20 miles
Distance travelled by Beth is 5 miles longer means 20 + 5 = 25 miles
Time took by Beth is 20 minutes more means = 30 + 20 = 50 minutes = 0.83 hrs
Average speed of Beth = distance / time = 25 / 0.8333
Average speed of Beth = 30 miles : Answer
Hope it will help :)
Answer:
Step-by-step explanation:
-0.5(3x + 5) and -1.5x + 2.5
-0.5(3x + 5)...distribute the -0.5 thru the parenthesis
-1.5x - 2.5
no, these are not equivalent.... one is -1.5x + 2.5 and the other is -1.5x - 2.5....not the same
