Question 906436
Please help me graph these two equations on a number line and write in interval notation….
 1) |4-3x| <= 13
-13 <= 4-3x <= 13
-17 <= -3x <=9
-3 <= x <= 17/3
Draw a number line
Plot x = -3 and x = 17/3 = 5 2/3
Put a solid circle at each of those values
Draw a line between the solid circles to see the total graph
Interval:: [-3,17/3]
==================================

2) |2x-5|-5 > 20
|2x-5| > 25
2x-5 > 25 or 2x-5 < -25
2x > 30 or 2x < -20
x < 10 or x > 15
Draw a number line; plot x = 10 and x = 15
Draw an open circle at x = 10 and at x = 15
Draw an arrow to the left from x = 10
Draw an arrow to the right from x = 15
Interval:: (-oo,10)U(15,oo)
===================
