After the outbreak of a mysterious disease, the average wait time at a hospital increased by 70\%70%. before the outbreak, the average wait time at the hospital was mm minutes. which of the following expressions could represent the average wait time at the hospital after the outbreak? choose 2 answers: choose 2 answers: (choice a) a \dfrac{170}{100}m 100 170 m (choice b) b 1.7m1.7m (choice c) c m+70m+70 (choice d) d m+0.7m+0.7 (choice e) e 0.7m0.7m

A.

B.

Step-by-step explanation:

Given,

The average wait time at the hospital was m minutes,

And, after outbreak it is increased by 70 %,

Thus, the average wait time at the hospital after the outbreak = The average wait time before outbreak + 70 % of the average wait time before outbreak

Hence, Option A and B are correct.

A. both coordinates are positive.

Step-by-step explanation:

I'm attaching a picture. The lower right quadrant/quarter is where x is positive and y is negative. When you "reflect over the y axis" it's mirroring the position by flipping it above the y axis.

In my picture, I used the example of a filled in dot in the lower right quadrant at +2 x, and -2 y. Right above that, in the upper right quadrant, there's an unfilled circle at +2 x, and +2 y. The second point is the first after being "reflected over the y axis." X stays the same, but the y goes from negative to positive.

I hope this helps. Please ask me if it's still confusing.
