Answer:
It is all determined by how many spaces and which way the decimal point moves.
Step-by-step explanation:
So here are two examples
<em>Example 1:</em>
500000.00
To write this in scientific notation you would move the decimal place to the left.
You would move it 5 digits to the left so the exponent of 10 would be 5

<em>Example 2</em>
0.0000042
Here to write this in scientific notation you move the decimal place to the right.
You would move it 6 digits to the right so the exponent would be -6

Answer:
None of these answers
Step-by-step explanation:
Plug the points into the equation to see if they make sense
(4,-10), -10=3(4)+2, -10=12+2, -10=14. Incorrect
(10,-4). -4=3(10)+2, -4=30+2, -4=32. Incorrect
(-10,-4), -4=3(-10)+2, -4=-30+2, -4=-28. Incorrect
Therefore, the answer is none of these answers
