HallsofIvy replied to a thread Line y = (x/2) + 3 in Pre-Calculus
Reflecting a point (a, b) about the line y= x gives the point (b, a). That is, it swaps the two coordinates. Given that y= (x/2)+ 3, x/2= y- 3 and...

MarkFL replied to a thread [SOLVED] 9.1.14 Use Euler's method to calculate in Calculus
Given: \d{y}{x}=f(x,y) Euler's method is the recursion: y_{n+1}\approx y_{n}+\Delta x\cdot f\left(x_n,y_n\right) Now, in the given...

I presume you wrote it that way because you can now factor "3t" out of "6t^2+ 3t and factor "7" out of "14t+ 7". What does that leave?

Check: if x= 7 then sqrt(x+ 2)= sqrt(7+ 2)= sqrt(9)= 3 while x- 4= 7- 4= 3. Those are the same so x= 7 satisfies sqrt(x+ 2)= x- 4. If x= 2,...

MarkFL replied to a thread 231.14.88 3d surface in Calculus
Multiplying through by $9+6x-8y$ and distributing the $26$, we obtain -x^2-y^2+z^2=156x-208y+234 -x^2-156x-y^2+208y+z^2=234 ...
