8.842 but the answer would have to be rounded because you can’t have .842 coaches... the answers 9!!!!
True, because they make up the two line segments make up the right angle
Answer:
K'= (-2, 4)
Step-by-step explanation:
First we are going to rotate our point 270° counterclockwise.
The rule for a 270° counterclockwise rotation is
, which means that we just need to interchange the coordinates of the point and change the sign of the x-coordinate:




Now, to shift the point 3 units down, we just need to subtract 3 units from the new y-coordinate of our resulting point form the previous procedure:



We can conclude that the coordinates of K' are (-2, 4)
3x-15=51
3x=36
X= 12
Thus the number is 12
Answer:
(-2,0)
Step-by-step explanation:
When finding the x intercept, substitute 0 for Y. -20/10=-2.
I hope this helps
