Answer:
The cave is at a depth of 25 meters away from the surface of the water
Step-by-step explanation:
Here, we want to know the location of the cave relative to the surface of the water.
Initially she was at a height of -15 meters relative to the surface of the water. What this simply means is that she was at a depth of 15 meters relative to the water surface.
Now, from that position, she went 10 meters deeper. So her new depth will be -15+(-10) which will be -25 meters
Thus the location of the cave is 25 meters away from the surface of the water
Answer:
3 (-11, -12), (-1,8)
Step-by-step explanation:
i hope it right
First we expand the brackets:
-2a + 8 + 6a = 36
4a + 8 = 36
We then need to get the a's onto one side and the numbers onto the other:
4a = 28
We can then divide to get an x by itself:
a = 28/4 = 7
Subtracting a negative number is like removing debt. When you remove debt, you effectively gave someone money and the value of their bank account increased.
Another answer is that “subtraction is addition of the opposite,” so subtracting a negative number is really adding a positive number, which again causes the other number to increase.
