Given: f(x)= 11x + 5 - 3x
Find f(7)
f(7)= 61
Simplify: 10x + 6 - 3x + 5 - 7y + 8y
7x + y + 11
Switch these equations to standard form: y= 3x - 5 and y= 8x + 7
-3x + y = -5 and -8x + y = 7

A data set has the following values: 10, 13, 15, 15, 18, 17, 20, 22, 24, 25. Calculate the mean, median, and mode.
How does replacing 25 with 30, affect the mean, median, and mode?
Mean: 17.9
Median: 17.5
Mode: 15
30 instead of 25:
Mean: 18.4
Median: 17.5
Mode: 15
The mean increases by 0.5. The median stays the same. The mode stays the same.
Rationalize the denominator and simplify: 5/√3
