F(x)=2x+4/3
Replace f(x) by y:
y=2x+4/3
Solving for x:
y-4/3=2x+4/3-4/3
Subtracting the two terms on the left side of the equation:
(3y-4)/3=2x
Dividing both sides of the equation by 2:
[(3y-4)/3]/2=2x/2
[(3y-4)/3]*(1/2)=x
[(3y-4)*1]/[(3)*(2)]=x
(3y-4)/6=x
x=(3y-4)/6
Replace "x" by "f^(-1) (x)" (inverse function) and "y" by "x":
f^(-1) (x) = (3x-4)/6 Inverse function
Then, for x=6
f^(-1) (6) = [ 3(6)-4]/6
f^(-1) (6) = (18-4)/6
f^(-1) (6)= 14/6
f^(-1) (6) = 7/3

3a(4a²-5a+12)
12a³-15a²+36a
~Hope this helped!~
The answer would be -15x+36. To solve this equation, you would first use distributive property and distribute the -9 to the values inside the parentheses (or multiply them). So, you would multiply -9 and x and -9 and -4 to get -9x+36-6x. Then, you combine like terms, which are -9x and -6x to get -15x. You can't simplify any further without knowing the value of x. Hope this helps!
Picture 1: The amount of tax for Veena's meal is $1.02
Picture 2: Christian reads
books per week.
Picture 3: 80% is equal to
.
Step-by-step explanation:
Picture 1: Veena ate lunch at a deli. She ordered turkey sandwich for $9.25 and a salad for $4.35. The tax was 7.5%. What is the amount of tax for Veena's meal.
Given,
Price of turkey sandwich = $9.25
Price of salad = $4.35
Total amount = 9.25+4.35 = $13.60
Tax = 7.5%
Amount of tax = 7.5% of total cost
Amount of tax = 
Amount of tax = 
The amount of tax for Veena's meal is $1.02
Picture 2: Christian reads 1/4 book every 2/3 week. How many books does Christian read per week?
Given,
Books read every 2/3 weeks = 1/4 books

For determining the number of books read per week, we will multiply both sides by 

Christian reads
books per week.
Picture 3: What percent is equivalent to
