Answer:
x = - 5
Step-by-step explanation:
Given
f(x) = - 4x - 10 and f(x) = 10, the equate right sides, that is
- 4x - 10 = 10 ( add 10 to both sides )
- 4x = 20 ( divide both sides by - 4 )
x = - 5
Mean is the "meanest" because it requires the most work. Add up the values in your data set and divide by the number of terms in the data.
Let x represent attendees at Harry's Hoedown, then
Mean =
41 =
123 = 48 + 33 + x
123 = 81 + x
42 = x
Answer: 42
2y=2_8
2y=_6
Divide both sides by 2 so that y can stand alone
Therefore y=_3
