Hi!
When we write a number in scientific notation, we write it like this:
N ×
N = a number between one and 10
x = negative if the decimal is moved to the right. positive if moved to the left.
Okay, so we need to move the decimal in the number <span>0.0059 to the right to make it between one and 10.
0.0059
00.059
000.59
0005.9
5.9
N = 5.9
5.9 </span>×
Since we moved the decimal to the right 3 times,
x = -3
5.9 ×
^ the answer
Hope this helps! :)

Answer:
x is equal to negative one, and y is equal to negative four.
Step-by-step explanation:
You can do this by solving one of the equations by either x or y, then substituting it into the other. Let's solve the second one for y:
Now we'll substitute that into the first equation:
So we now know that x is equal to -1. We can simply substitute that into one of the original equations to find y:
We now know that x is equal to -1, and y is equal to -4. We can also check our answer by plugging that -4 into the other equation, and see if we still get -1:
So we know that our answer is correct.
