Help? Right now I mainly need help with question 17, the graph thingy, and 14.

For 17 it should be...if I still remember right anyway...
PQB = 6x + 15
BQR = 3x
BQR = PQA
PQB + PQA = 180 (degrees)
6x + 15 + 3x = 180
6x + 3x = 180 - 15
9x = 165
x = 18.3...3
PQB = 6x + 15
PQB = 6(18.3) + 15
PQB = 125

took discrete math a few years so may be a little sketchy with it


14)
statement: (j)->(~w)
inverse: (~j)->(w)
converse: (~w)->(j)

Thanks I did all those questions. I actually have another question here it is.

For the given open sentence find a solution for the variable that will allow it to become a true statement given the domain: (4, 5, 6, 7, 8, 9)

6x +17 =89

EDIT: Don't worry I did the whole graph.

Me too.

5x^2 = 80
/5 /5
x^2 = 16
sqrt sqrt
x = 4
