Suppose you receive a $50 gift certificate to the cityside music and book store. all cds at the strore cost $9.99, and all books cost $5.99. you want to buy some books and at least one cd.

a. write a system of inequalities for x books and y cds that describes thia situation

b. graph the system to show all possible solutions

c. what puchase does the ordered pair (2,6) represent? is it a solution to your system? explain.

d. find a solution in which you spend almost all of the gift certificate

d for sure  it is d

Step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
