Adepartment store advertised that for every $25 you spend at the store, you get $2 off your total bill. nate's bill came to $154 before the discount. he figured he would get a $12 discount. is his claim reasonable? explain.

Complex numbers multiply √-4 * √-25 and show all intermediate steps. alternative notation is sqrt(-4) * sqrt(-25).

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

This is a rational expression because the denominator contains a variable. this is a polynomial with 3 terms. this is a rational expression because the denominator contains a variable. this is a polynomial with 4 terms. this is a rational expression because the denominator contains a variable. this is a polynomial with 4 terms. this is a rational expression because the denominator contains a variable. this is a polynomial with 3 terms. this is a rational expression because the denominator contains a variable. this is a polynomial with 5 terms.
