A rectangle is inscribed in the region bounded by the x-aix, the y-axis, and the graph of x=2y-8=0. Write the area as a function of x. Then determine the domain of the function. What are the dimensions of the rectangle that will produce the maximum area?

Unfortunately, I can't draw the diagram of the graph and the shaded box region, but on the x-axis, the width 4 and on the y-axis, the length is 2.

im taking an online course and out of the 220 problems they assigned to get done in 3 days, ive managed to answer all but about 12. so i am posting 4 here. Please help me with all of them if you can, if you can only help me with 1 or 2 no big deal its still much appreciated. thank!


1)i=prt, solve for p

2)y=mx+b solve for m

3)(ab)/c = d/e solve for e

4)a + b = 3 (r + r *sub one*)b solve for r sub one

Assume an economy is characterized by the following equations: c=200+.8(y-t), I=400-20r, (M/P)^d=Y-100r,?
M=4000
P=2
G=300
T=200
What is the equations for the IS and LM curves? Wat are the equilibrium levels of output and interest rate?
LM Curve =(M/P)
IS Curve =200+.8(y-t)+400-20r

Solve the system and state if it is an independent or dependent system.
12) 4x + 2y = -10
3x + y = -6

13) 3x + 4y = 18
4x - 5y = -7

14) 2/3x + 1/4y = 4
X = -3/8y + 6

15) 1/2x + 1/3y = 6
Y = 1/2x + 2

28) State and explain your method of solution, and then state your answers
Y = -4x
X - y = -10

29)2x - 2y = 5
5x - 3y = 11

30) 3x - 2y = 0
7x - 8y = 10
