Dependent variable is dependent on the independent variable
independent variable influences the dependentvariable
number of months influences the hcost
independent=number of months
dependent=cost
for the cost for 4 or 2 months, just start at months=2 or 4 and go up till you hit the line
equation=y=mx+b
m=slope
b=yintercept or starting point
solid line
initial fee=20
see attachment, black lines are what they are
2 months=$80
4months=140
rate is $30 per month
equation is c=30m+20
dashed line
intial fee=50
attachment, blue is dashed points
2months=$70
4months=$90
rate is $10 per month
equation is y=10x+50
X=8
To find the X-intercept/zero, substitute Y=0
0= -3/2+12
Then Just solve for X

Answer:
Mean: 5
Median: 4
Mode: 4
Step-by-step explanation:
Mean:
1. To find the mean given a data set, you have to add up all the data points and then divide them by the number of data points there is.
Therefore, the mean is 5.
Median:
1. To find the median given a data set, we first have to arrange the data points in order.
2. Next, we have to find which data point is in the middle. In this case, the middle number is 4.
Therefore, the median is 4.
Mode:
1. To find the mode given a data set, you just have to find which data point is the most frequent.
- 1 data point of 2
- 3 data points of 4
- 1 data point of 6
- 1 data point of 8
Because the most frequent value is 4, the mode is 4.
It’s 3 - remember pemdas. you do 6-2 first, which is 4 and divide 12 by 4 which is 3 :)
Answer:
x is equal to 3 and y is equal to mines1
Step-by-step explanation:
add both together and you will get
![5x = 15](https://tex.z-dn.net/?f=5x%20%3D%2015)
and then it is easy to solve
