Both sides are equal to 6x-18, so both are the same line, meaning every point is intersecting on the lines, so the answer is (c). Move the decimal 10 places to the right, since that's what the exponent is. You only moved it 8 places.

**Math - help really needed**

You actually get (1/tan^2x)+1, which is cot^2 + (csc^2x-cot^2x), which is csc^2x, which is 1/sin^2x. And that's your answer. (You could only cancel out the tan^2 if it were (Some #)(tan^2x)/tan^2x, rather than (1)+(tan^2x)/tan^2x. Dividing is the inverse of multiplying, so...

**Math - help really needed**

I'll give you a hint: Try replacing the 1 with tan^2x/tan^2x. After add that to 1/tan^2x, replace the denominator (the tan^2x) with sin^2/cos^2.
