The first one is C y=-2x+20 the second ones is 17.6
it is 20 minuets that she went over on her bill
20% = 0.20.2 * 1630 = 326
|6x + 5| = 7 · 3
|6x + 5| = 21
6x + 5 = 21 (1st equation)
-6x + 5 = 21
(1st equation)
6x = 21 - 5
6x = 16
x = 8/3
(2nd equation)
-6x - 5 = 21
-6x = 21 + 5
-6x = 26
x = -13/3
so all of the solutions are;
x = -13/3, 8/3
