Answer:
x=-5, y=-1
Step-by-step explanation:
Substitute x=-4+y into -2x-5y=15. So we have
-2(-4+y)-5y=15
8-2y-5y=15
-7y=7
y=-1
And x is -4+y so x= -4+(-1)= -5.
The cost for a company to manufacture "x"....
These statements tell you what X is. (The word cost refers to what the function will tell us. In other words C(x) = The Cost for the Company))
So as we keep going the problem goes onto:
.... bracelets
So the number of bracelets is X.
The function is: C(x)
And how functions work are quite simple. You plug in a number (x) and get out a number (y).
So, C(256) = 1536
So, they made 256 bracelets at a cost of 1536 dollars.
This is no different than if I said the function was:
C(x) = 6x
And then asked, what would the function equal when x = 256. It's the same thing, so don't let it trip you up!
Answer 1: 1536$
Answer 2: 256
