Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.

Which inequality is equivalent to -3x < -12? x < 4 , x < -4 , x > 4, x > -4

What is the slope of the line shown below?
