A stereo system is marked with a price of $479. The sales tax on the system is $28.74. What is the sales tax rate

6%

Step-by-step explanation:

To find the sales tax rate you would divide the 28.74 by the total price of 479 to get .06 and you would have to multiply this by 100 to make it a percentage and that would be 6%

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
