Question 72487: (x-1)^2 + (y-8)^2 = 16
I've tried giving x a value and solving for y. Here is what I tried...
(1-1)^2 + (y-8)^2 = 16
0 + (y-8)^2 = 16
(y-8)(y-8) = 16
y^2 -8y -8y =64 = 16
y^2 - 16y + 64 = 16
y^2 - 8(y-y+8) = 16
y^2 + 8 =2
y^2 = 16
y = 4

: I have tried to figure this out and have no idea! I can seperate out some of the information I need, but then I ahve no idea how to orginize it into useable for. Word problems confuse me!
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 300 h per week. The plants capacity is limited to a tatal of 18 radios per week, and existing orders require that at least 4 AM raidos and at least 3 AM/FM radios be produced per week. Write a system of in equalities representing this situation. Then draw a graph of the feasable region given these conditions, in which x is the number of AM radios and y is the number of AM/FM radios.This question is from textbook Beginning Algebra
