Answer:
x =
Step-by-step explanation:
Square both sides.
y² = (2x + 1) / (x - 1)
Multiply both sides by (x - 1).
y²(x - 1) = 2x + 1
xy² - y² = 2x + 1
xy² = 2x + 1 + y²
xy² - 2x = 1 + y²
x(y² - 2) = 1 + y²
x =

Answer:52+3+4
Applying exponential properties, the simplified base for the function is given as follows:
<h3>What is the function?</h3>
The function is represented by the following definition:
As an exponent, the function is given by:
27 can be simplified as follows:
27 = 3 x 3 x 3 = 3³
Hence:
Then, the 3 at the exponent multiplies 2x and can be simplified with the 3 of the root, hence:
Hence the simplified base for the function is given as follows:

Answer:
60 is 5$ of 1200
Step-by-step explanation:
Find the value of the ratio 60/1200 and then multiply the result by 100%:
(1/20)(100%) = 5%
-4n-8=-12n+8
-4n+12n=8+8
collect the like terms
8n=8+8 then you add 8+8
8n=16 divide both sides by 8
n=2
