Answer:
the marked answer is correct
Step-by-step explanation:
The desired end result is an identity matrix in the first three columns. The diagonal values are 1, as needed, so what remains is to eliminate the off-diagonal values. In row 2 that can be done by adding row 3 to it.
The next step should be to add rows 2 and 3 and replace row 2 with that sum.

Please give me brainliest!
The domain is the X values and the range is the y values.
The blue line starts at X 0 and Y 0 and moves up and to the right.

The 3rd choice is the correct one.
Check the picture below.
notice chord QR is a diameter, thus the vertex at P has a right-angle by Thales theorem.
Answer:
12 meters far.
Step-by-step explanation:
The question translates to 10+2. The word problem states that the height of the platform is 10 meters. That means we can say that he'd have already traveled 10 meters down when he dived. And the problem also states that the diver goes two meters under the water, meaning that he had traveled 2 meters, in addition to the 10 meters. And so, we add the 10 and 2 to get 12 meters in total.
