The inverse of the given function is (6x + 2)/3.
What is the inverse of a function?"The inverse of a function is a function that undoes the operation of that function. The inverse of a function exists if and only if the function is bijective"
Given function is
F(x) = (3x - 2)/6
⇒ y = (3x - 2)/6
If we write 'x' instead of 'y' and 'y' instead of 'x', then we get:
x = (3y - 2)/6
⇒ 6x = (3y - 2)
⇒ 3y = 6x + 2
⇒ y = (6x + 2)/3
Therefore, F⁻¹ (x) = (6x + 2)/3

What is an angle ?An angle is a mathematical term which we can defined, when two straight lines or rays meets at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.
Interior angles:- The inner angle made by the intersection of two polygonal sides.
Exterior angles:- The outer angle made by the intersection of two polygonal sides.
Given that,
All the exterior angles are,
(5x + 4), (7x + 4),(4x + 9),(4x + 1),(9x-6)
It is known that,
Sum of Interior angle & Exterior angle is equal to 180°
So we can calculate all the Interior angles,
180°- (5x + 4), 180°-(7x + 4), 180°-(4x + 9), 180°-(4x + 1), 180°-(9x-6)
Formula for sum of all the Interior angles = (2n-4)×90
So, n=5
Sum of all the Interior angles = 540°
[180°- (5x + 4)] + [180°-(7x + 4)]+[180°-(4x + 9)]+[180°-(4x + 1)] +[180°-(9x-6)] = 540
900- 29x- 12 = 540
x = 12
Hence, The value of x is, 12

A car went 64 miles on 2 gallons of gas in the morning, 16 miles on 1/2 gallon of gas at noon, and 32 miles on 1 gallon of gas at 5:00 PM. Is the amount of gas used proportional to the distance the car drove? Why or why not?
Answer:
Yes,
Step-by-step explanation:
You take 64 miles for 2 gallons and divide it by 2. And it leads up to 32 miles and 1 gallon. Now you divide that by 2 again and get 16 miles and 1/2 gallon. So, to check that you can take 16+16 and you get 32 and take 32+32 and you get 64.

Submit Answer
attempt i outot
Answer:
$187
10b + 13c
Step-by-step explanation:
Payment for babysitting = $10 per hour
Payment for clearing tables = $13 per hour
How much money would Stella earn in a week in which she worked 7 hours babysitting and 9 hours clearing tables?
Total weekly payments = Payment for babysitting × number of hours + Payment for clearing tables × number of hours
= 10 × 7 + 13× 9
= 70 + 117
= $187
How much money would Stella
week in which she worked b hours babysitting and c hours clearing tables?
Total weekly payments = Payment for babysitting × number of hours + Payment for clearing tables × number of hours
= 10 × b + 13 × c
= 10b + 13c
what is the name of this shape?
Answer:
this shape consists of a square and triangle
The shape is a Pentagon ... but that won't help get the perimeter or area. you'll have to find the areas and perimeters of both the square and triangle and then add them for the final answer.
Area of figure = area of square + area of triangle
=> Area of Square = a² (a = side)
side = 3.5 cm ...so...
Area of square = a²
= 3.5 × 3.5
= 12.25 cm²
=> Area of Triangle = ½ × base × height
= ½ × 3.5 × 1.64
= 2.87cm²
Area of figure = area of square + area of triangle
Area of figure = 12.25 + 2.87
= 15.12 cm²
Perimeter of figure = P of square + P of triangle
=> P of square = 4a
= 3.5 × 4
= 14cm
=> P of isosceles triangle = 2a + base
= 2 × 2.4 + 3.5
= 4.8 + 3.5
= 8.3cm
Total perimeter of figure = P of square + P of triangle
Total perimeter = 14 + 8.3
= 22.3 cm

The equation that models this relationship is y=2x. How many liters of water should Austin combine with 16 scoops of juice mix? Write your answer as a whole number or decimal.
Answer:
8 liters
Step-by-step explanation:
Given that:
y = 2x
where y is the number of scoops of juice mix, and x is the liters of water required.
To determine the liters of water required for 16 scoops of juice mix;
y = 16
So that,
16 = 2x
x = [tex]\frac{16}{2}[/tex]
= 8
x = 8 liters
Therefore, Austin would combine 8 liters of water to the 16 scoops of juice mix.
A combination of 3 erasers and 5 pencils cost $7.55. A combination of 6 erasers and 12 pencils cost $17.40. How much is each pencil?
Answer:
9.85
Step-by-step explanation:
I subtract 17.40 and 7.55 to get 9.85 they just wanted to know how much the pencil cost not erasers.
The cost of each pencil is $1.15.
What is a system of equation?A system of equations is used when there are two variables, and you are given two pieces of information about how those variables are related.
Given that, A combination of 3 erasers and 5 pencils cost $7.55. A combination of 6 erasers and 12 pencils cost $17.40.
Let e represents eraser and p represents a pencil.
Establishing the equations,
3e+5p = 7.55
6e+12p = 17.40
Solving by elimination, we get,
p = 1.15
Hence, The cost of each pencil is $1.15.

The Pythagorean Theorem, given by the formula a^2+b^2=c^2, relates the three sides of a right triangle. Solve the formula for the positive value of a in terms of b and c.
Answer:
c=√a²b²
Step-by-step explanation:
The positive value of 'a' in terms of b and c will be [tex]a =\sqrt{b^2-c^2}[/tex].
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
It is given that the formula of the Pythagorean theorem for a right-angle triangle is, a² + b² = c².
The value of c is calculated as:-
a² + b² = c²
Reverse the equation to calculate a.
c² = a² + b²
Taking b² to the left side then the equation will become:-
a² = c² - b²
Taking square root on both sides of the equation.
[tex]\sqrt{a^2}=\sqrt{c^2-b^2[/tex]
[tex]a = \sqrt{c^2-b^2}[/tex]
Therefore, the positive value of 'a' in terms of b and c will be [tex]a =\sqrt{b^2-c^2}[/tex].

Raymond just got done jumping at Super Bounce Trampoline Center. The total cost of his session was \$43.25$43.25dollar sign, 43, point, 25. He had to pay a \$7$7dollar sign, 7 entrance fee, and \$1.25$1.25dollar sign, 1, point, 25 for every minute he was on the trampoline.
Answer:
29 minutes
Step-by-step explanation:
Given
[tex]Total = \$43.25[/tex]
[tex]Entrance\ Fee = \$7[/tex]
[tex]Per\ Minute = \$1.25[/tex]
Required
Determine the number of minutes (t) that he was on the trampoline.
This can be expressed as:
[tex]Total\ Payment = Entrance\ Fee + Amount\ per\ minute * t[/tex]
Where t represents the number of minutes
Substitute values for Total, Entrance Fee and Amount per minute
[tex]43.25 = 7 + 1.25 * t[/tex]
[tex]43.25 = 7 + 1.25t[/tex]
Solving further to get the value of t, we have:
[tex]1.25t = 43.25 - 7[/tex]
[tex]1.25t = 36.25[/tex]
[tex]t = 36.25/1.25[/tex]
[tex]t = 29[/tex]
Answer:
29 minutes
Step-by-step explanation:
7 + 1.25t = 43.25 is the equation
How did I solve this?
I divided those two and that is how you get the equation
In total is 29 minutes

. Which is an equation of the line?
Answer:
y = 3x + 3
Step-by-step explanation:
Given parameters;
Coordinates of the line;
(-2, -3)
Slope of the line = 3
Unknown:
Equation of the line = ?
Solution:
The equation of any straight line is often expressed as;
y = mx + c
y and x are the coordinates
c is the intercept
Now insert values of y, x and m to find c;
-3 = 3(-2) + c
-3 = -6 + c
c = -3 + 6 = 3
The equation of the line is;
y = 3x + 3
