5>x because you can subtract 5 from both sides and 3x from both sides
Answer: second option.
Step-by-step explanation:
Given the transformation 
→
You must substitute the x-coordinate of the point A (which is 
) and the y-coordinate of the point A (which is 
) into to find the x-coordinate and the y-coordinate of the image of the point A.
Therefore, you get that the image of A(2,-1) is the following:
You can observe that this matches with the second option.
Answer:
0.51, √5, 5.1% x 10^-3

so this means that you only have to calculate the number of 10 sets of black keys and thats 5 x 10.
hope this helps : )
