Question 81636: Convert 43/6 to a mived number.
This one I'm a bit confused, b2 2bc + c2 if b = 3 and c = 2.
with the 2bc, do I multiply the three numbers together, or do I do each one seperate.
combine like terms.
5w + 5x 9w- how do i figure out what goes where. I'm trying to understand if the w and x represent something or I'm supposed to complete the equation as if they werent there.
Use the indicated property to write an expression that is equivalent to the following expression.
(7 + 11) + 2 (associative property of addition)

Question 81664: I can't seem to fully understand how to get through the whole process to the answer.

in the book the problem states as follows:
5y-3x=15
let y=0 5y-3x =15
5(0)-3x =15
-3x =15
x =15
let x=0 5y-3x =15
5y-3(0)=15
5y =15
y =3
let y=6 5(6)-3x =15
30-3x =15
-3x = - 15
- 15
x = -15/-3 or 5
okay, this is the example in the book. I dont understand where the uses of the 6 as y comes in. Please help. thank you.

Question 81637: I'm learning how to write my "results" in slope-intercept form. And I'm having a little difficulty trying to get these worked out and was wondering if I could get some assistance.
(0,5),m= -3/5
(-1,3) and (4,-2)
(2,-3) and (2,4)
I could really use the step by step process of how to do this, if possible. Thank you.

Question 82144: A small firm produces both AM and AM/FM car radios. The AM radios take 15h to produce, and the AM/FM radios take 20h. The number of production hours is limited to 300h per week. the plant's capacity is limited to a total of 18 radios per week, and existing orders require that at least 4 AM radios and at least 3 AM/FM radios be produced per week.
Write a system of inequalities representing this solution.
Then draw a graph of the feasible region given these conditions, in which x is the number of AM radios and y the number of AM/FM radios.
