You are required to take five courses, one each in humanities, sociology, science, math, and music. you have a choice of 3 humanities courses, 2 sociology courses, 3 science courses, 8 math courses, and 3 music courses. how many different sets of five courses are possible?

step-by-step explanation:

it's 15

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel
