Answer:
x>-9
Step-by-step explanation:
Look at the denominator,
since (x-6)/(x+9) is a fraction,
x+9=0
x=0-9=-9,
so x must be any number greater/larger than -9 in order to let the whole fraction be less than 1.
In general, you solve a problem like this by identifying the vertices of the feasible region. Graphing is often a good way to do it, or you can solve the equations pairwise to identify the x- and y-values that are at the limits of the region.
In the attached graph, the solution spaces of the last two constraints are shown in red and blue, and their overlap is shown in purple. Hence the vertices of the feasible region are the vertices of the purple area: (0, 0), (0, 1), (1.5, 1.5), and (3, 0).
The signs of the variables in the contraint function (+ for x, - for y) tell you that to maximize C, you want to make y as small as possible, while making x as large as possible at the same time. The solution space vertex that does that is (3, 0).

x=−4 2/5
Step-by-step explanation:
Answer:
If its radius is 9 cm, it’s circumference would be two times radius times pi equal to 18 pi. Also its area is pi R squared which is equal to 81 pi. Circumference = 18 pi Area = 81 pi Area is 4.5 times greater than the circumference. The answer is C.
