## chevygirl 2 years ago Can someone explain? Solve and graph each inequality. 4x-15<17

1. stgreen

|dw:1356369971555:dw|x<8

2. chevygirl

What?

3. stgreen

what what?? 4x-15<17 implies x<8

4. chevygirl

ok? that doesnt help but thanks for helping

5. stgreen

uh come on what you want??

6. chevygirl

nothin never mind

when a question is asking for a 'solution' it is asking 'what are all the values of x that will cause this equation to be true?' Since the equation involves an inequality ('<' less than sign) there is more then one solution, in fact there are a great many. A number line is a visual representation of the solutions. When you see a question like this solve as you would an equality (an equation with an equal sign): \[4x-15<17\] \[4x <32\] \[x<8\] now in order to represent ALL the values less than eight you have to draw a number line and highlight them: |dw:1356370813323:dw| The open circle on eight means that eight is not actually included (it would be shaded in otherwise) and the arrow point to the left means that the solution continues to infinity
