10 - 2x = 120
120 + 10 = 130
130 / 2 = 65
x = 65
2(65) - 10 = 120
Answer:

Step-by-step explanation:
Notice when x increases 1, y is 4 times the previous one, so
the function is like 
To determine the constant C, put any pair of (x, y)
Use x = 0, y = 0.2, so
0.2 =
= C * 1 = C
then 
Answer: The answer is 51,208,811

Answer:
--- 1 over 5 squared
Step-by-step explanation:
When multiplying terms with a common base, you just add the exponents:

That's true even when you don't have any exponents.


A negative exponent isn't fully simplified, so there's another rule to use:

That is '1 over x to the y' if it's too small to read.

The answer is C
(9)(5)=-45
9+(-5) = 4
