Answer:

Step-by-step explanation:

You have to understand two things about this question.

  • f(x) is a relative of y. So maybe it would help you if you wrote y = 2x^2
  • The second thing you have to understand is when you see a number used instead of the x, that number goes into every x on the right.

f(-3) = 2(-3)^2

f(-3) = 2 * 9

f(-3) = 18

Remember that (-3) ^2 = -3 * - 3 = 9 a positive.

Ty has 5 goats and 19 carrots. He gives each goat the same number of carrots, and he uses as many carrots as he can. How many ca
velikii [3]

Each goat gets 3 carrots.

After giving 3 carrots to each of the goat, 4 carrots are left with Ty in total.

Step-by-step explanation:

Here, the total number of carrots  = 19

The total number of goats  = 5

So, in the given condition:

19 is the DIVIDEND

5 is the DIVISOR

Now, dividing 19 by 5, we get:

19  = 5 x 3 +  4

Here,  3 = Quotient

4 = Remainder

So, by the given equation. we can say that:

Each goat gets 3 carrots.

After giving 3 carrots to each of the goat, 4 carrots are left with Ty in total.
