Chance spent $1,189 on textbooks during his freshman year at college. If he bought 13 textbooks, what was the average cost of each textbook?

91.46

Step-by-step explanation: All you have to do is divide 1,189 by 13 and you get 91.46

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
