Answer:
(x, y) = (5, -8)
Step-by-step explanation:
The value of y is found by evaluating the equation for x=5.
y = 7 -3(5) = 7 -15 = -8
For x = 5, y = -8. As an ordered pair, this is (x, y) = (5, -8).
Answer:
The indifference point is 8 weeks.
Step-by-step explanation:
<u>First, we establish the total cost formula for each:</u>
x= number of weeks
Club:
Total cost= 20 + 15*x
Retail:
Total cost= 17.5*x
<u>Now, we equal both formulas and isolate x:</u>
20 + 15x = 17.5x
20 = 2.5x
8=x
The indifference point is 8 weeks.
<u>Prove:</u>
Total cost= 20 + 15*8= $140
Total cost= 17.5*8= $140
Answer:
The range in a data set is the difference between the highest and lowest values in a group of numbers. In order to find the range you have to order the data from least to greatest. Then you have to subtract the lowest number from the highest number. For example, the numbers are 21, 32, 45, & 80. You have to subtract 80-21 = 59. So, <u>in this case</u> 59 would be your range.
Step-by-step explanation:
This is a website that tells you how to find the range of a set of data, feel free to check it out- https://www.mathgoodies.com/lessons/vol8/range
What number you have to multiply 2 to get 5.
Or 2*x=5 solve for x
22 minutes = 15 rows
1 minute = 15 ÷ 22
90 minutes = (15 ÷ 22) × 90
= 61.36 (recurring)
≈ 61 (whole number)
