Find the Inverse - f(x) = 5x - 6
Answer:
f⁻¹(x) =
Step-by-step explanation:
Given function,
→ f(x) = 5x - 6
We are supposed to find ths inverse of the given function. Consider the function, y = f(x).
→ y = 5x - 6
Add 6 to both sides.
→ y + 6 = 5x - 6 + 6
Solve the equation.
→ y + 6 = 5x
Division both sides by 5.
→ y + 6/5 = 5x/5
Solve the equation.
→ (y + 6)/5 = x
Can be re-written as,
→ x = (y + 6)/5
Now, recall f(x) = y, this implies x = f⁻¹(y).
→ f⁻¹(y) = (y + 6)/5
So the final answer is:
→ f⁻¹(x) = (x + 6)/5

Answer:
x = 13
Step-by-step explanation:
Vertical angles are always congruent (equal)
⇒ ∠A =∠B
⇒ (8x - 12) = (6x + 14)
⇒ 2x = 26
⇒ x = 13
Angle A and Angle B are vertical angles . If mAngle A = ( 8x - 12 )° and mAngle B = ( 6x + 14 )°, then find the value of x .
Given : -Angle A = ( 8x - 12 )°Angle B = ( 6x + 14 )°To Find : -We have to find the value of x
Concept : -Concept of this question belongs to vertical angles i.e. vertical angle are always equal .
So Starting Our Solution : -Angle A = Angle B 8x - 12 = 6x + 14 8x - 6x = 14 + 122x = 26x = 26/2x = 13[tex] \pink{\boxed {Therefore , \: value \: of \: x \: i s \: 13}}[/tex]
Verification : -We are verifying our answer by putting the value of x in given Angle A and Angle B ,
Angle A = Angle B( 8x - 12 )° = ( 6x + 14 )°[ 8 ( 13 ) - 12 ]° = [ 6 ( 13 ) + 14 ]°( 104 - 12 )° = ( 78 + 14 )°92° = 92°L.H.S = R.H.SHence, Verified .Therefore , our answer is correct .
#Keep LearningEnter a range of values for x.

Answer:
-5
Step-by-step explanation:
The range of values for x is {2, 26, 2.5, 5} in the given case where we have to enter values.
To provide a range of values for x based on the given information, we need to solve the equation 2x+10 = 14, 62, 15, and 20.
Let's solve the equation for each given value: 1. 2x+10 = 14:
Subtract 10 from both sides of the equation: 2x = 4
Divide both sides of the equation by 2: x = 2 2. 2x+10 = 62:
Subtract 10 from both sides of the equation: 2x = 52
Divide both sides of the equation by 2: x = 26 3. 2x+10 = 15:
Subtract 10 from both sides of the equation: 2x = 5
Divide both sides of the equation by 2: x = 2.5 4. 2x+10 = 20:
Subtract 10 from both sides of the equation: 2x = 10
Divide both sides of the equation by 2: x = 5
Therefore, the range of values for x is {2, 26, 2.5, 5}.

Write an equation in point-slope form for the graph shown below?
Answer:
y-4=-2/5(x+5)
Step-by-step explanation:
Points slip form is y-y₁=m(x-x₁)
Since you have a graph we can see the line goes down 2 and over 5. Since the slope is going downwards it is a negative slope. This mean m=-2/5. Then pick any point on the line ( I chose (-5,4)) and plug it in for y₁ and x₁.
In a kickball game, a ball is kicked and travels along a parabolic path. The height h, in feet, of the kickball t seconds after the kick can be modeled by the equation h(t) = −16 t2 + 24t .
a. A fielder runs a route that will allow him to catch the kickball at about 3 ft above the ground. Write an equation that can be used to find when the fielder will catch the ball.
b. Use graphing technology to find out how long the kickball has been in the air when the fielder catches it on its descent. Round to the nearest hundredth.
The equation h(t) = -16t² + 24t is an illustration of a quadratic model
The equation when the fielder catches the ball is -16t² + 24t = 3The fielder will catch the ball after 0.14 seconds or 1.36 secondsThe equation when the fielder catches the ballThe equation that represents the path of the kick ball is given as
h(t) = -16t² + 24t
The fielder catches the ball at a height of 3 ft above the ground.
This means that:
h(t) = 3
So, we have:
-16t² + 24t = 3
Hence, the equation when the fielder catches the ball is -16t² + 24t = 3
How long the ball has been in the air whenIn (a), we have:
-16t² + 24t = 3
Rewrite as:
-16t² + 24t - 3 = 0
Next, we determine the solutions of -16t² + 24t - 3 = 0 using a graphing technology
From the graph (see attachment), we have the following solutions
t = 0.14 and t = 1.36
Hence, the fielder will catch the ball after 0.14 seconds or 1.36 seconds

What is a cone and a circle?
A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.
The volume of a cone is expressed as;
V = (1/3)πr²h
Where r is radius of the base, h is the height of the cone and π is constant pi ( π = 3.14 )
A circle is simply a closed 2-dimensional curved shape with no corners or edges.
The circumference of a circle is expressed mathematically as;
C = 2πr
Where r is radius and π is constant pi ( π = 3.14 )
Given the data in the question;
Volume of the cone ( silo ) V = 132ft³Height of the silo h = 6ftRadius r = ?We substitute our values into the expression above find the radius of the base of the silo.
V = (1/3)πr²h
132ft³ = (1/3) × 3.14 × r² × 6ft
132ft³ = 6.28ft × r²
r² = 132ft³ / 6.28ft
r² = 21.0191ft²
r = √21.0191ft²
r = 4.58ft
Now, since the radius of the base of the silo is 4.58ft, the circumference of the base will be;
C = 2πr
C = 2 × 3.14 × 4.58ft
C = 28.8ft
Therefore, the circumference of the base of the silo that the farmer plans to build to store chicken feed is 28.8 ft.

Mrs. Burgess will go to the gym on 20 different days this month. A one day pass to the gym costs $9.65. A monthly pass to the gym costs $145. How much will Mrs. Burgess save by buying a monthly pass?
Answer:
Mrs. Burgess will save $48 by buying a monthly pass.
Step-by-step explanation:
Let's compare the one-day pass to the monthly pass by finding how much 20 one-day passes will cost.
Multiply the price for a one day pass, $9.65, to the gym by 20 days:
$9.65 * 20 = $193Compare this price to the monthly pass price by subtracting these values.
$193 - $145 = $48If Mrs. Burgess buys the monthly pass of $145 instead of buying 20 day passes for $193, she will save $48.

A local Target store bought 90 pizzas at Pizza Hut for its holiday party. Each guest ate 1/6 of a pizza and there was no pizza left over. How many guests did Target have for the party?
By taking a quotient, we will see that the number of guests is 540.
How to find the number of guests?
Because we know that each guest ate a fixed amount of pizza, and there was no pizza left, we know that the number of guests will be equal to the quotient between the total number of pizzas bought, and the amount of pizza that each guest ate.
This is:
[tex]N = \frac{90}{1/6}[/tex]
We can rewrite that quotient as:
[tex]N = \frac{90}{1} / \frac{1}{6} = \frac{90*6}{1*1} = 540[/tex]
So the number of guests is 540.

Find the dimensions of the rectangle if the length is (x+8), the width is (x+3) and the area is 234ft^2
The dimension of the rectangle 18 feet by 13feet
How to calculate the area of a rectangleA rectangle is a 2 dimensional shape having two sides.
Area of a rectangle = length * width
Given the following parameters
Length = x + 8
Width = x + 3
Area = 234ft^2
Substitute the given parameters into the formula
(x+8)(x+3) = 234
x² + 3x + 8x + 24 = 234
x² + 11x = 234 - 24
x² + 11x = 210
x² + 11x - 210 = 0
Factorize
x² + 21x - 10x - 210 = 0
x(x+21) - 10(x+21) = 0
x - 10 = 0
X = 10
Leength = x + 8
Length = 18 feet
Width = x + 3
Width = 3 + 10
Width = 13feet
Hence the dimension of the rectangle 18 feet by 13feet
