I need the ordered pairs for <br> y-3x&lt;10
adelina 88 [10]

Answer:

(0, 5) and (5,0) are two possibilities.

Step-by-step explanation:

There is an infinite number of ordered pairs that satisfy your inequality.

To help you pick some ordered pairs, you could plot the inequality (see the graph below).

Any point within the shaded area is a solution.

Pick an ordered pair, insert it into the equation, and check if the inequality is true.

Here are two examples.

<em>For (5, 0</em>):

0 – 3×5 < 10

   0 - 15 < 10

       -15 < 10     True

<em>For (0, 5)</em>:

5 – 3×0 < 10

   5 – 0 < 10

         5 < 10     <em>True </em>

The ordered pairs (0, 5) and (5,0) are part of the solution set of the equation y – 3x < 10.

Answer:

6x + 3h

Step-by-step explanation:

F(X) = 3x^2

F(X+h) = 3(X+h)^2

then F(X+h) - F(X) / h

= 3(X+h)^2 - 3x^2 / h

= 3(x^2 + 2hx + h^2) - 3x^2 / h

= 3x^2 + 6hx +3h^2 - 3x^2 / h

= 6hx + 3h^2 / h

= h (6x +3h) / h

= 6x + 3h

I hope this answer is correct
