Kyle sell 40 pizzas, he sold 1/4 then neighbor bought 1/2 of the remaining pizzas. How many pizza did the neighbor buy?

15

Step-by-step explanation:

If he sold 1/4 then 40 x 1/4 = 10

So he has 30 left

30 x 1/2 = 15

The neighbor bought 15

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
