Answer:
0.782
2.1%
Step-by-step explanation:
Answer:
A. 4
Step-by-step explanation:
Constant of proportionality (k) = y/x
We can use the coordinates of any point on the line to find k.
Let's use (2, 8)
Constant of proportionality (k) = 8/2
Constant of proportionality (k) = 4
Since there are three variables and three constants you add like terms.
3(x+15) = 3x + 40
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.
