We know that g(x) = \frac{3}{x^2+2x}
We have to find g^-1(x) or inverse of g(x)
Inverse of g(x) can be determined by equating g(x) to y, and determining the value of x in terms of y
g(x) = y = \frac{3}{x^2+2x}
⇒ y × (x² + 2x) = 3
⇒ yx² + 2xy = 3
⇒ yx² + 2yx - 3 = 0
Determining the roots of x using:
x =
OR x =
, where a is coefficient of x², b is coefficient of x, and c is the constant
⇒ x =
OR x = 
⇒ x =
OR x = 
Hence, g^-1(x) =
OR x = 
Answer:
A. -10
Step-by-step explanation:
I think you would do like this:
y=2x-5
what about 2y(2x-5) times 2)
so 2y=4x- (-10)
Hi there,
Remove parenthesis,
7 + 9 + (-4)
Then, use the addition and subtraction rules:
7 + 9 - 4
Hence, the answer is 12 (C)
Hope this helps :)
Answer:
2.5 gallons
Step-by-step explanation:
Make the denominators of the fractions the same and combine them


Then simplify the fraction

Then subtract how many gallons you have from how many you want

You will need 2.5 gallons to make 3 gallons
