The cost (in dollars) in making b bracelets is represented by 4+5b. The cost (in dollars) of making b necklaces is represented b
ddd [48]
Answer:

P(b)=3b+2

Step-by-step explanation:

The cost (in dollars) in making b bracelets is represented is

B(b)=4+5b

The cost (in dollars) of making b necklaces is

N(b)=8b+6

To find how much more it will cost to make b necklaces than b bracelets, we find the difference,

P(b)=N(b)-B(b)

P(b)=8b+6-(4+5b)

P(b)=8b+6-4-5b

P(b)=3b+2

This is a polynomial in descending powers of b, hence it is in standard form;

How many solutions does the equation -4y + 4y + 2=2
Luden [163]

Answer:

Infinite Solutions

Step-by-step explanation:

If you look at the equation careful you will see this part "-4y+4y".  If you see that the variables cancel each other out leaving 2=2.  That means that for any value of y, 2=2.  Because the variable cancels itself out it doesn't mater what the variable is.  So there is an infinite amount of values you can have for "y".
