Need ! consider the function represented by the equation 16b = 4r - 12. write the equation in function notation, where b is the independent variable. must show work for full credit

r(b) = 4b +3

Step-by-step explanation:

There are only two variables and the one that is not b is r. So, this amounts to solving for r. Divide the given equation by the coefficient of r:

... 4b = r -3

Add the constant:

... 4b +3 = r

Express in function notation.

... r(b) = 4b +3

maya’s expression will generate the wrong sum because she violated the commutative property.

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
