Ineed i do not understand i'm only 8

1) 8

2) 42

3) 4

4) 17

5) 6

7) 60

Step-by-step explanation:

1. Yes, because 1 minus 3 can't happen, since 3 is bigger than 1.

2. No, because 6 minus 4 can happen, since 6 is bigger than 4.

3. No, because 9 minus 5 can happen, since 9 is bigger than 5.

4. Yes, because 5 minus 8 can't happen, since 8 is bigger than 5.

5. Yes, because 0 is nothing, and you can't subtract a number bigger than it by it.

6. No, because a number can be subtracted by itself to get 0.

Step-by-step explanation:

When you subtract 2 numbers, you have to sometimes carry a number over to the first digit (meaning put the number that you had over the first digit of the first number). Here is an example:

5 67 17

-29

36

You have to subtract, and since 7 is smaller than 9, you have to borrow 10 from the 6 in 67, so that you add 10 to 7, to make 17, which is bigger than 9 and can be subtracted. When you do that, you get 6, so you put the 6 down, and cross out 6 to make it 5, since it is in the 10ths place, it makes sense to change it to 5. Subtarct the numbers, and you get your answer!

I hope this helps :)

(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)
