Answer:
Step-by-step explanation:
We have been given that the figure B is a scaled copy of figure A. We are asked to find the scale factor of from figure A to figure B.
To find the scale factor, we will divide side length of figure B by its corresponding side in figure B.
We can see that side in figure B is 64 units and its corresponding side in figure A is 16 units.
Therefore, the scale factor is 4.

Hi there!
We are given the equation:
x² - 2y = 7
To verify if each ordered pair is apart of the function, we can plug in their respective x and y values:
1. (5)² - 2(8) = 7
25 - 16 = 9 ≠ 7. This is NOT correct.
2. (-1)² - 2(-3) = 7
1 + 6 = 7. This is correct.
3. (-4)² - 2(-11.5) = 7
16 + 23 = 39 ≠ 7. This is NOT correct.
4. (1.2)² - 2(-2.78) = 7
1.44 +5.56 = 7. This is correct.
Thus, only 1 and 4 are the correct answers.
