IF (-20, -39) is a solution to y = 2x + 1 which statement is TRUE. a.
(-20, -39) is solution because

When I graphed the line, y = 2x + 1, the point (-20, -40) lies on that line. In addition, when I plugged in -20 for x and -39 for y and the equation was true!

b.
(-20, -39) is a solution because

there an infinite number of points on a line and ALL points lie on y = 2x + 1.

c.
Don't know what to do!

d.

True. (-20, -39) is NOT a solution.

I couldn't graph the point (-20, -39) on the provided coordinate plane.

The accompanying table shows the numbers of male and female students in a particular country who received bachelor's degrees in business in a recent year. complete parts (a) and (b) below. business degrees nonbusiness degrees total male 189131 634650 823781 female 169539 885329 1054868 total 358670 1519979 1878649 (a) find the probability that a randomly selected student is male, given that the student received a business degree. the probability that a randomly selected student is male, given that the student received a business degree, is nothing. (round to three decimal places as needed.) (b) find the probability that a randomly selected student received a business degree, given that the student is female. the probability that a randomly selected student received a business degree, given that the student is female, is nothing. (round to three decimal places as needed.)
