Step-by-step explanation:
Please find the attachment.
Let x be the number of hours the student swims per day.
We have been that a student swims one hour every day, so in 2 months the student will swim 60 hours.
We are also told that the student swims 800 meters each day. This means that slope of the graph that represents the total meters swam during the time of her training program will be 800.
So in 60 days the student will swim .
We can see from our attached graph that at x equals 60 our y is approximately 48.
Since y-axis represents the number of meters in thousands, so 48 stands for 48,000.
Therefore, attached graph is the right choice.
Answer: D) reflection across y = -x
Explanation:
When we reflect over y = x, we basically swap x and y. So for instance, the point (3,1) becomes (1,3).
When reflecting over y = -x, we will do the same thing but we'll make each coordinate swap in sign from positive to negative (or vice versa). The rule for reflecting over y = -x is
So if we apply that rule to point A(3,1) then it becomes A ' (-1, -3).
Similarly, B(1,5) moves to B ' (-5, -1)
Finally, C(6,9) becomes C ' (-9, -6)
