5(n+3)-7n when n = 3.2

8.6 is your answer

Step-by-step explanation:

5(3.2+3)-7×3.2=-12.8

Step-by-step explanation:

5(3.2+3)-7×3.2

=5×6.2-7×3.2

=5(-0.8)×3.2

= -4×3.2

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

  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.
