A 20 gallon bathtub is draining at a rate of 2.5 gallons per minute. The number 8 of gallons remaining is a function of the number m of minutes.
Does this situation represent a linear function?

Using the completing-the-square method, find the vertex of the function f(x) = 2x2 − 8x + 6 and indicate whether it is a minimum or a maximum and at what point. maximum at (2, –2) minimum at (2, –2) maximum at (2, 6) minimum at (2, 6)

Which expression is equivalent to 8(k + m) − 15(2k + 5m)?

{0,1,2,3,4,5,6,20,21,22,23,24,25} the distribution is considered to be: skewed the right, skewed the left, not skewed?
