Lines a and b are parallel. line c is perpendicular to both line a and line b. which statement about lines a, b, and c is not true? line a and line b have the same slope. the sum of the slopes of line b and line c is 0.the product of the slopes of line c and line b is −1.the product of the slopes of line a and line c is −1.

⇒ The sum of the slopes of line b and line c is 0.

⇒   False ⇒ NOT true

The sum of the slopes of line b and line c is 0.

Step-by-step explanation:

Remember that the product of the slopes of two parallel lines is -1, so in order to be -1 you have to multiply M*-1/m=-1 so since to add them up you would do it like this m+(-1/m) taht wouldn´t get as result 0, so that would be the option that is not correct, remember that parallel lines have the same slope, so that also eliminates all of the other options.

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
