Serena sold 8 pitchers of lemonade. She used the same amount of lemons in each pitcher. She had three lemons left over. Write an expression to represent the total numbers of lemons she had

8m+3

Step-by-step explanation:

Let m be the number of lemon used in a pitcher of lemonade.

Serena sold 8 pitchers of lemonade, therefore she used 8m lemons.

Since there is a leftover of 3 lemons, we add:8m+3

Therefore:

Total number of lemons Serena has can be determined by the expression: 8m+3

where m is the number of lemons used in one pitcher of lemonade.

  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.
