4x<4 means x<1 If you graph this on the number lines, you need an open circle at 1 and a solid line from 1 going to the left forever.

13 less than 4 times a number 13 less than is "-13" 4 times a number is "4x" 4x-13■
It's easiest to break this into parts. First look at the numbers being multiplied (4 times a number). Since you don't know this number, you have to use x. So 4 times x is 4x. Then you need to know what 3 less than 4x is, so you would simply subtract, giving you 4x-3.
8x + 8 = 4x 4x + 8 = 0 4x = -8 x = -2
VV2-4x+4y-4=0
use a line graph. Place a solid dot at 4. Shade the entire region to the left of 4.x is Less than shade Left.* * * * * The above answer is so very wrong - it has missed out the key word "absolute".Use a line graph. Put a solid dot at -4 and another solid dot at +4 and join them. Every point on the line (including the two end points) is the graph.
