Can someone help me understand this question about Linear Programming? I can't seem to wrap my head around the concept. Thank you!

The larger of two number is 4 less than twice the smaller number. the sum is 41. find the numbers

1. writing an equation for an exponential function by 2. a piece of paper that is 0.6 millimeter thick is folded. write an equation for the thickness t of the paper in millimeters as a function of the number n of folds. the equation is t(n)= 3. enter an equation for the function that includes the points. (-2, 2/5) and (-1,2)

Find the solution on the interval [0, 2pi)
