Step-by-step explanation:

x and x - 20 are adjacent angles and are supplementary , thus

x + x - 20 = 180

2x - 20 = 180 ( add 20 to both sides )

2x = 200 ( divide both sides by 2 )

x = 100

x - 20 = 100 - 20 = 80

11x - 2 and 75 are corresponding angles and are congruent, thus

11x - 2 = 75 ( add 2 to both sides )

11x = 77 ( divide both sides by 11 )

x = 7

11x - 2 = 11(7) - 2 = 77 - 2 = 75

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
