1. ### Help solving this questions

I have a math problems i am having issues with. I am trying to solve the following equation for y in terms of x. Cant leave a fraction in either the numerator or denominator of the answer and no repeating decimals.
2. ### solving y'=1/x

Advance apologies for the lack of formatting--I'm new, but I'll learn quickly. So I'm looking to find a particular solution of y'=1/x, satisfying (-1,1). I note that this must come from the family y(x)=ln[abs(x)]+C, substitute x=-1 and y(x)=1 to get that C=1. So my desired particular solution...
3. ### Solving Systems of Equations with Absolute Value Operators

Suppose we have a line formula: Y = m * (X) (Eq. 1) where m is our slope and our y-intercept is zero. Let us assume that m is always positive. Now let us suppose that Y and X are actually functions of two hidden variables, P and Q. Y = |P + Q| (Eq. 2) X = (|P| + |Q|) /...
4. ### Need help solving for part of fractional exponent

Want to solve for x in equation: y =a^(1/x). Unable to isolate x on left side of equation so get equal values on both sides when replacing y & a with numbers. This is the orig equation with numbers: 0.01 = 0.67^(1/x) Thanks for any help.
5. ### Solving system of equations

Please help me find a solution so I can guide my son. I will not solve it for him, but can raise a red flag if I see him go on the wrong direction. Find all values for which there exists an ordered pair satisfying the following system of equations: List only the values for Thanks a lot.

7. ### Word problems/ Writing and solving equations

I am currently reviewing for the ACT, and I want to be as prepared as humanly possible. However, I've been stumped by the following questions, and have no idea as to how they've managed to find their answers. If anyone could help me understand my mistakes, it would be greatly appreciated...
8. ### Looking for verification on a function and solving for different variables.

logb(CL) = e # solve for L be = CL logC(be) = L # solve for C be = CL logL(be)= C I'm pretty sure L is right but what am I doing wrong when solving for C? Preciate any help anyone can provide. Thx.
9. ### Solving inequality

Would someone mind showing me how to solve the following inequality? $\sqrt{10-x} - \sqrt{x} \leq 2$? The answer is supposed to be $x \in [1, 10]$. It's a bit confusing for me (Worried) Thanks in advance!
10. ### solving complex equations

does anyone know to solve an equation of 1/ surd(x) = -2log( [(1.33x10^-3)/3.7 ] + [2.51 / (7.4x10^6)(surd x ) ] ) this is an physics equation , but i dont know how to solve it mathematically how to find the value of x ?
11. ### Solving for H

My stepson has a problem that ask him to rearrange an equation to solve for h, a, b using this equation. A=1/2 (a+b)h Mathway solves it for "h" as: h=2A-1/2(a+b) see picture attached. How does the "2" get to be infront of the "A"? Thanks!
