Solve each linear equation for x.
1. 1/3(x + 6) = 12
2. 12(x + 1/6) = 8
3. −3(x + 2) = −18
4. −3(x − 2) = 21
5. −5(4 − x) = −40
6. 1/4(6 − x) = 1/4

To find the extreme values of a function f(x. y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x, y)=xy
