Can someone tell me how to do these problems? (you don't have to do all of them, you can do one of each and tell me how you got that).
1)sketch graphs
2)slope intercept form of equation
3)simplify, rewrite in standard form

3(10x-y)-5(x-y^2) need this solved asap

Find parametric equations for the line tangent to the curve of intersection of the surfaces at the given point. surfaces: xsquared2plus+2yplus+2zequals=1212 yequals=33 point: left parenthesis 1 comma 3 comma five halves right parenthesis

Iwill give ! if m∠a=59 and m∠3=81°, what is m∠b? m∠b= _[blank]_°
