Answer:
Step-by-step explanation:
The given statement is;: 'I think of a number, multiply it by 3, add 4 & square the result.'
At first, let's take the unknown number as 'x' . (asked in the question).
So, the number we think about = x
Now, we need to multiply it by 3. So,
- 3 * x = 3x
In the next part, we need to add 4 to it so,
- 3x + 4
Now, by squaring the result, we'll get the expression as,
- <u>(3x + 4)²</u>

Answer:
A. (2, 4)
Step-by-step explanation:
The ordered pairs represent (x, y). Since you have y =2x, this is the same as ...
(x, 2x)
That is, the second number in the pair needs to be twice the first number in the pair. Since you know your times tables, you know that this is not the case for (1, 0), (10, 5) or (4, 12). Those values of x would give (1, 2), (10, 20), (4, 8).
It is the case that you have (x, 2x) for (2, 4).
The point (2, 4) lies on the graph of y = 2x.
