Answer:
The speed is 2/9 miles per minute
Step-by-step explanation:
Speed is defined as the distance covered per unit time.
The formula for speed is given by:

Let s be the speed, d be the distance and t be the time then

Given

The speed will be calculated by dividing the number of miles by minutes
So putting the values in the formula

Hence,
The speed is 2/9 miles per minute
Y = -8x - 5/4......slope here is -8 or -8/1
y = 1/8x + 4/5...slope here is 1/8
what u have here are negative reciprocal slopes....negative reciprocal of a number can be found by flipping the number and changing the sign. So the negative reciprocal of -8/1 is 1/8 (see how I flipped the number and changed the sign)...and when u have negative reciprocal slopes, this means that ur lines are perpendicular.
Answer: s = 1.44
Step-by-step explanation:
11 - 18*s = -15
-18*s = -15 - 11
-18*s = -26
18*s = 26
s = 26/18
s = 13/9
s = 1.44
