Mean: add all numbers together and divide by the amount of numbers there are.
8 + 9 + 8 + 11 = 36
36/4 = 9
mean = 9
Median: Find the middle number. Since in this case it has an even amount of numbers, add the two middle numbers and divide by 2
8 + 9 = 15
15/2 = 7.5
median = 7.5
Mode: The number that shows up the most
Mode = 8
Range: Subtract the smallest number from the largest number
11 - 8 = 3
Range = 3

Answer:
y=mx+b is the slope intercept form.
Step-by-step explanation:
m is the slope (how the line is moving across the graph)
b is y-intercept (where the line crosses the y axis)
Hope this helps!
9+6=15 and 15-12=3 so this =3 the -(-6) becomes positive
How to solve with elimination: with the equations on the top, add the number on top and bottom if they share a variable such as x. do the rest for all of the numbers.

Answer:
16 and 4
Step-by-step explanation:
If x is the smaller one, then the larger is 4x. Their sum is ...
