There are 250 students taking band, chorus, or both. if there are 180 students taking band and 60 students in both band and chorus, how many students are only in chorus?
a.10
b.60
c.70
d.120

The multiplicative property of equality states that for real numbers a, b, c, and d, if a = b and c = d, then ac = bd. true false

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

Is there a direction u in which the rate of change of f(x,y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
