If there are 5 student and 9 of them come back from where they were and 0 leave and come back, how many student are there? pls answer i need with this 85 points

Solve the system of equations y= 3/2 - 1, -x+ y =-3

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form. −three fourthsx + y = 10 3x − 4y = −40 y = three fourthsx + 12 y = three fourthsx + 10

1/2+1/6-3/4 simplify the given expression leaving the answer in improper fraction form.
