**algebra B**

Using the formula, w = cr^-2, solve for r. An object weighs 100lbs. What value of C will result in r = 3963? I have another question similar, but if someone could guide me in this one, I can figure out the other one. Thanks,

**Math (Algebra II)**

I'm trying to finish up my summer math packet, and I'm almost done, but I'm having trouble figuring out this one: "Divide and simplify these expressions." (3x^4 - 2x^3 + 16x - 192) / (x^2 - 8) so, that's 3x to the 4th, minus 2x cubed, plus 16x, minus 192 ---> all divided by...

**Math, Still Need Help!**

Label each statement TRUE or FALSE. a. The sum of two one-to-one functions is one-to-one. b. The product of two one-to-one functions is one-to-one. c. If f is a one-to-one function and k is a real number (constant), then the function g(x)=k*f(x)is one-to-one.

**One more algebra!**

If r>0, then for all p and q such that pq does not equal 0 and pr>qr we have a. -p > -q b. -p > q c. 1 > -q/p d. 1 < q/p e. none of these This one I do not get at all, either. Please walk me through it. Thank you!

**Algebra**

Seven times the difference of six and a twice a number yields the same result as the same number decreased by one. How does this translate into an algebra statement?
