I need help with a couple of these it’s due by Thursday

How do the graphs of y = 1/x and y=5/x+6 compare?

Find the volume of the described solid.the solid lies between planes perpendicular to the x-axis at x = 0 and x=7. the cross sectionsperpendicular to the x-axis between these planes are squares whose bases run from the parabolay=-31x to the parabola y = 30/x.a) 441b) 147c) 864d) 882

Ineed with math stuff it involves graphs
