Elimination method. i need with the middle one and perhaps the second one as well. there can't be any fractions! you!

The function g(x) is defined as shown. x-1, -2 g(x) = 2x+3, -1 6-x, x23

Kapil needed to buy a long wooden beam. he went to two sawmills that each charge an initial fee plus an additional fee for each meter of wood. the following equation gives the price (in dollars) of a wooden beam from the first sawmill as a function of its length (in meters). p = 5+20xp=5+20x

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.
