-4m + 8m = -16
4m = -16
m = -16 / 4
m = -4
Answer:
3. Option 2 (Perpendicular)
4. Option 3 (neither)
Step-by-step explanation:
3.
m1 = -7/8
Second equation: -8x + 7y = -21
7y = 8x - 21 y = (8/7)x - 3
m2 = 8/7
m1 & m2 are not equal, so not parallel
Since m1×m2 = (-7/8)(8/7) = -1,
They are Perpendicular
4.
m1 = -1/4
Second equation: -2x + 8y = 6
8y = 2x + 6 y = (1/4)x + 3/4
m2 = 1/4
m1 & m2 are not equal, so not parallel
Since m1×m2 = (-1/4)(1/4) = -1/16, not -1. They are not Perpendicular either. So, neither
Answer:
Number 4 is H
Number 5 is B
Step-by-step explanation:
You want to start by finding the per hour speed.
125 miles / 3 hours ≈ 41.6666666… miles each hour
If you drive that speed for 5 hours: 5 hours * 41.6666… mph ≈ 208.333… miles
