Answer:
A. Move the decimal point to the left
Step-by-step explanation:
Given that:
The scientific notation = 10⁻¹⁰
Let recall;
That the standard notation usually took the form of an inverse:
For example;
Let say 10⁻¹ will be
in scientific notation;
SO, 
Now; we are given 10⁻¹⁰ as a scientific notation,
To standard notation, we get:

= 0.01
Thus, it is true to say that the decimal point will be moved to the left side when converting a number from scientific notation to standard notation if the power of 10 is -10.
A would be the correct answer because he is up in elevation so that makes the 1200 positive and he goes down 20.4 which is negative and is goes that far down!!
hope this helps
Step-by-step explanation:
The equation of the line is y = 4x - 9.
Answer:
-16x+14y-45z
Step-by-step explanation:
4x+4y-5(4x-2y+9z)
we apply the distributive property:
4x+4y-5*4x-5*(-2y)-5*9z
so we have:
4x+4y-20x+10y-45z
-16x+14y-45z
