9.85-8.975 equala 0.875
Since the product of the slope is -1, hence the lines are perpendicular
<h3>Parallel and Perpendicular lines</h3>
Two lines are known to be parallel if they have the same slope while if two lines are perpendicular if the product of the slope is -1
Given the coordinates of line 1 passing through (0, 6) and (6, 4), the slope is given as;
Slope = 4-6/6-0
Slope = -2/6
Slope = -1/3
Similarly for the coordinate points (-1, -7) and (1, -1).
Slope = -1+7/1+1
Slope of line 2 = 6/2
Slope = 3
Take the product of the slopes
Slope = -1/3 * 3
slope = -1
Since the product of the slope is -1, hence the lines are perpendicular

0.5 of a mile - since 5,280ft = 1 mile and half of 5,280 is 2,640
If you are mixing a 30% solution with a 20% solution to obtain a 14% solution, you will never obtain a 14% solution.
Answer:
D
Step-by-step explanation:
John is 10cm taller than Peter, if Peter is h than John's height would be h+10 since it is Peter's height plus ten.
