The problem looks something like this:

Find the limit as x approaches 2 of (6-x)^(1/2) -2 divided by (3-x) ^(1/2) -1.

The problem in words is: the square root of (6-x) minus 2 divided by the square root of (3-x) minus one.

the answer should be 1/2 but i keep getting it wrong. How am i suposed to multiply it?

Okay, I have tried EVERYTHING, but I can't seem to get this! I don't know why! Maybe it's because I'm missing some part (i.e. the theta part) of my equation, but maybe someone can help me... I'll pick a best answer TODAY! Thank you SO much! Please show me step-by-step how to solve this! Thanks!

This text was printed on a four-color web heatset offset press. A cylinder on this press has a 13.37 inch diameter. The linear speed of a point on the cylinder's surface is 18.33 feet per second. What is the angular speed of the cylinder, in revolutions per hour?

What also confuses me is, should the units be in feet or inches? I've tried both, but I can't seem to get it! Hmmmmmm!

Solve the system of equations using the addition (elimination) method.
If the answer is a unique solution, present it as an ordered pair: (x, y). If not, specify whether the answer is “no solution” or “infinitely many solutions.”
2x – 7y = 3
-4x + 14y = -9
