Ответ:
Collect like terms, ie do 9n-4n = 5n ...
5n will then be exactly divisible by 5 as 5n / 5 = n

Step-by-step explanation:
The function is h(x) = 2x + 4. H(x) is basically just another way of writing "y", so we technically have y = 2x + 4. We can complete the table by substituting the value of x that the table gives us.
The table gives us x = -4 and wants us to find h(x), or y. So, we do y = 2(-4) + 4 and we get y = -4.
The table gives us x = -3 so we do y = 2(-3) + 4 and we get y = -2.
The table gives us x = 1 so we do y = 2(1) + 4 and we get y = 6.
The table gives us x = 3 so we do y = 2(3) + 4 and we get y = 10.
The table gives us x = 4 so we do y = 2(4) + 4 and we get y = 12.
