If you roll a number cube 78 times, how many times do you expect to roll a 4?

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10

Hurry im being timed the graph of f(x)=x^3-3x^2+4 is shown based on the graph how many distinct real numbers solutions does the equation x^3-3x^2+4=0 have

What is the slope-intercept from of the equation y+5=4(x+8)?
