Find the slope of the line through each pair of points (19, -16), (-7,-15)
Answers
plug the numbers into the equation:
((-15) - (-16)) / (-7) - (19)
(-15+16) / (-7-19)
1 / -28
The answer is -1/28

First, lets multiply both sides by 6 so that n is a whole number:
90-n=n-6
now you group like terms on each side, to do this you add n to each side and add 6 as well so it becomes:
96=2n
Now divide both sides by 2 so you have 'n' on one side and it is:
48=n
Hope this helps :)
Step 1: Simplify both sides of the equation. Simply steps provided.
15−1/6n=1/6n−1
15+−1/6n=1/6n+−1
−1/6n+15=1/6n−1
Step 2: Subtract 1/6n from both sides.
−1/6n+15−1/6n=1/6n−1−1/6n
−1/3n+15=−1
Step 3: Subtract 15 from both sides.
-1/3n = -16
Step 4: Multiply both sides by -3 -1/3 by 16.
Your answer is:
n = 48

Answer:
A) The cost is the same at 5 months.
Step-by-step explanation:
Lets use m to represent the number of months it will take for the cost to be the same. If we set up an equation, we can write:
75 + 10m = 50 + 15m
-50 on both sides
25 + 10m = 15m
-10m on both sides
25 = 5m
Divide by 5 on both sides.
5 = m
That means it will take 5months for the costs to be the same.
