Bianca bought a pack of rechargeable batteries for $9.99. If the sales tax on the batteries is 3% and Bianca
pays with $11 cash, how much change will she get back?

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
