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 shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x

Find the axis of symmerty for x y=x squared -4x-8
