Answer:
The first option ,f^-1(x)=1/2*x-1/2
Step-by-step explanation:
f(x)=2x+1
y=2x+1
Interchanging the places of x and y, we get,
x=2y+1
(x-1)/2=y
f^-1(x)=(x-1)/2
f^-1(x)=1/2*x-1/2
The first option.
The equations of the function is
Y=2x+ 5y
Y<(less than or equal to) 36
X+y>( greater than or equal to) 3
So to find one variable in the equation such as finding the amount of roses or carnations, you would have to do system of equations. Some ways of using system of equations is to use substitution, elimination, or graphing.
Answer:
17.39%
Step-by-step explanation:
We can summary the question:
- Probability of students using Google chrome= 0.49
- Probability of students using other browsers = 0.51
So the probability that you need to pick 7 students to find 2 students using Google Chrome is:
P(G) =
* (
)(
) = 21*0.2401*0.03 = 0.1739 = 17.39%
With the interest rate his bank account will grow $36 dollars each year which after fiver years is $180 so the amount in the end will be $780
Distributive property is being used to get 8x-4x+6.
