= 16 * 10^13
which in scientific notation is 1.6 * 10^14
Answer: Upper right corner
=========================================================
How I got that answer:
The line y = x goes through (0,0) and (1,1). You would normally extend this line out as far as you can in both directions. However, the inequality x < -1 says you can only graph this if x is less than -1. We will not graph any part of the graph that is beyond x = -1 to the right. So we only have a small piece of it. The left piece of y = x. There is an open hole at the endpoint.
Similarly, y = -x is only graphed if x >= -1. We have a closed endpoint here. This graph goes through (0,0) and (1,-1). We erase the portion that is to the left of x = -1.
Doing all this leads to the upper right corner choice as our answer. The bottom right corner is close to the answer, but the open and closed endpoints are in the wrong spots.
Answer:
Step-by-step explanation:
- log8(216) + [log(42) - log(6)] ÷ log(49) =
- log (216)/ log (8) + [log (7) + log (6) - log (6)] ÷ 2 log (7) =
- 3 log (3) log (2) / 3 log (2) + log (7) / 2 log (7) =
- 3 log (3) + 1/2
