Answer: i think it’s no real solutions
Step-by-step explanation:
Answer: second option
Step-by-step explanation:
To find the inverse function of the given function f(x):
You need to:
Substitute into the function:
Now, you need to solve for "x", to do this, you must divide both sides of the function by 2:
Now, replace "x" with "y" and replace "y" with "x":
Therefore, substituting you get:
or
Though you did not list the points, I can tell you how to solve for the question.
One way to tell if a point lies on a given line is to take the point and plug it into the equation. If the equation remains true, then the point lies on the line. For example:
If we have the point (1,1), we can plug in 1 for x and 1 for y and see if the equation is true:
-8a-3b+6b-5a+9b= -13a-18b
-8a-5a=-13a
3b+6b+9b=18b

Answer:
C.
Step-by-step explanation:
First, we calculate the amount if ammonia in 22 gallons of 16% ammonia solution.
16% * 22 gal = 3.52 gal
The amount of ammonia remains the same after the water evaporates, but the total amount of solution is reduced by the amount of water that evaporates.
amount of ammonia: 3.52 gal
amount of water that remains: 22 - n
desired concentration, 24% = 24/100
Equation:
(3.52)/(22 - n) = 24/100
Answer: C.
