Question 157253: i need help with solving a problem
-7/8 (this is a fraction) -7 x < 21
8 _

the problem states solve the inequality . write the solution in interval notation. NOTE The < has a line under it there was no way to put it in on the computer



solve the formula for the given variable
2)v=1/3 (pie symbol) r to the 2 h for h

You can put this solution on YOUR website!
Note: you could have written the problem as: -7/8x<=21 (where / is the fraction bar and <= means less than or equal to). This way you only take up one line




-%287%2F8%29x%3C=21 Start with the given inequality.


cross%288%29%28-%287%2Fcross%288%29%29x%29%3C=8%2821%29 Multiply both sides by the LCD 8


-7x%3C=168 Multiply.


x%3E=%28168%29%2F%28-7%29 Divide both sides by -7 to isolate x. note: Remember, the inequality sign flips when we divide both sides by a negative number.


x%3E=-24 Reduce.

Answer:

So the answer is x%3E=-24




So the answer in interval notation is [)


Also, the answer in set-builder notation is



Here's the graph of the solution set




Note: the endpoint is a closed circle
