Consider the function.
f(x) = -2/3x-24
Which conclusions can be drawn about f^-1(x)? Select two options.
Answers
Answer:
Statement 3
Step-by-step explanation:
y = -2/3x-24
Make x the subject
y + 24 = -(⅔)x
x = -(3/2)(y + 24)
Intersection variables
f^-1(x) = -(3/2)(x + 24)
Slope: -3/2
No domain restrictions
y-intercept: x = 0
-(3/2)(0+24)
-36
(0,-36)
x-intercepts: y = 0
0 = -(3/2)(x + 24)
x = -24
(-24,0)
Linear function, range is all real values of y
Answer:
[tex]f^{-1}(x)\: \textsf{ has a y-intercept of }\:(0,-36)[/tex]
[tex]f^{-1}(x)\: \textsf{ has a range of all real numbers.}[/tex]
Step-by-step explanation:
Given function[tex]f(x)=-\dfrac{2}{3}x-24[/tex]
The given function has an unrestricted domain and range.
Domain: (-∞, ∞) → all real numbersRange: (-∞, ∞) → all real numbersInverse of a function[tex]f^{-1}(x)[/tex] is the notation for the inverse of the function. The inverse of a function is a reflection in the line y = x
Finding the inverse of the given function
Swap f(x) for y:
[tex]\implies y=-\dfrac{2}{3}x-24[/tex]
Rearrange the equation to make x the subject:
[tex]\implies -\dfrac{2}{3}x=y+24[/tex]
[tex]\implies -2x=3y+72[/tex]
[tex]\implies x=-\dfrac{3}{2}y-36[/tex]
Swap the x for [tex]f^{-1}(x)[/tex] and the y for x:
[tex]\implies f^{-1}(x)=-\dfrac{3}{2}x-36[/tex]
The inverse function has a slope of -3/2
The domain of the inverse function is the range of the function.
The range of the inverse function is the domain of the function.
Therefore, the domain and the range are unrestricted.
Domain: (-∞, ∞) → all real numbersRange: (-∞, ∞) → all real numbersThe y-intercept of the inverse function is when x = 0:
[tex]\implies f^{-1}(x)\: \textsf{ has a y-intercept of }\:(0,-36)[/tex]
The x-intercept of the inverse function is when y = 0:
[tex]\implies -\dfrac{3}{2}x-36=0[/tex]
[tex]\implies -\dfrac{3}{2}x=36[/tex]
[tex]\implies x=-24[/tex]
[tex]\implies f^{-1}(x)\: \textsf{ has a x-intercept of }\:(-24,0)[/tex]
Conclusion[tex]f^{-1}(x)\: \textsf{ has a y-intercept of }\:(0,-36)[/tex]
[tex]f^{-1}(x)\: \textsf{ has a range of all real numbers.}[/tex]

Answers
Answer:
Justin has a lower mean tip for the week with $42.
Step-by-step explanation:
To find the mean you must add all the numbers and then divide the sum by how many numbers there are.
For Justin you must add 32 + 45 + 50 + 33 + 50 then you'll get the sum 210. There are 5 numbers so you divide 210 by 5 which gives you the quotient 42.
As for T.J. you add 58 + 48 + 40 + 42 + 42 which gives you the sum of 230. Then you divide 230 by 5 since there's 5 numbers. Now you have the quotient of 46.
46 is greater than 42 so Justin has the lower mean.
Answer:
Justin by 4
Step-by-step explanation:
you add all the numbers for T.J. and for Justin separately and divide by five. you get 42 for Justin and 46 for T.J.

A full jar of honey weighs 750 grams, and the same jar two-thirds
full weighs 550 grams. What is the weight of the empty jar in grams
Answers
Answer:
150 grams
Step-by-step explanation:
The weight of the full jar of honey is equivalent to x + y, where x is equal to the weight of honey and y is equal to the weight of the jar.
x+y = 750
2x/3+y = 550
You can solve for y in the first equation and get:
y = 750-x
Plug that in to the second equation and you get:
-x/3+750 = 550
Subtract 750 from both sides:
-x/3 = -200
Multiple -3 on both sides:
x = 600 grams
The weight of the jar is 750-600 or 150

At a pet store, Rhonda paid $11.50 for 3 dog bowls and 4 bones.
Kelly paid $13 for 2 dog bowls and 8 bones. How much will Andrew
pay for 4 dog bowls and 2 bones?
help
Answers
Answer:
$8.75
Step-by-step explanation:
Lets put the number of dog bowls as "x" and the number of bones as "y" When we write the equation it comes out like this:
3x+4y=$11.50
2x+8y=$13
Make the "x" equal on both side so we find the lcm of 3 and 2 which 6 so we multiply 2 on the top and 3 on the bottom which changes the equation to
6x+8y=$23
6x+24y=$39 Then we subtract which equals
-16y=-$-13
y=13/16 or 0.8125 we put the "y" on the equation which makes
3x+3.25=11.50 To solve the question: 4(13/16) + 2(2.75)=$8.75 3x=8.25: x= 2.75
Final answer:
Andrew will pay $12 for 4 dog bowls and 2 bones, after calculating the individual prices of the items by setting up and solving a system of equations based on Rhonda's and Kelly's purchases.
Explanation:
To determine how much Andrew will pay for 4 dog bowls and 2 bones, we need to establish the price of a single dog bowl and a single bone. We can do this by setting up two equations based on the transactions made by Rhonda and Kelly.
Let B be the price of one dog bowl and O the price of one bone. Therefore, Rhonda's purchase gives us the equation 3B + 4O = $11.50. Kelly's purchase gives us the equation 2B + 8O = $13.
We can solve this system of equations either by substitution or by the elimination method. In this case, elimination may be more straightforward:
Multiply the first equation by 2, which gives us 6B + 8O = $23.We now subtract Kelly's equation from this, resulting in (6B + 8O) - (2B + 8O) = $23 - $13, simplifying to 4B = $10.Now we know that one dog bowl costs B = $2.50.To find the cost of one bone, we substitute B = $2.50 into either of the original equations. Using Rhonda's equation: 3($2.50) + 4O = $11.50, which simplifies to $7.50 + 4O = $11.50, and further to 4O = $4, meaning O = $1.00.With the prices determined, Andrew's total cost for 4 dog bowls and 2 bones will be 4B + 2O, which equates to 4($2.50) + 2($1.00).Calculating this gives us $10 + $2, which is a total of $12 that Andrew will pay.What is the degree of the polynomial

Mrs Lopez drives a number of miles north. Then she drives 34 miles west. She drives 94 miles in all. Complete the number sentences to show how many miles she drives north.
? +_ = _ and _ - _ = ?
Answers
Answer:
60
Step-by-step explanation:
number of miles driven north plus 34 equal 94.
subtract 94 from 34 to get your answer.
Mrs. Lopez drives 60 miles north.
The completed number sentences are:
60 + 34 = 94 and 94 - 34 = 60.
What is number sentence?Let's assume Mrs. Lopez drives x miles north.
The number sentence for the total distance she drives can be written as:
x + 34 = 94
This equation represents the sum of the distance she drives north (x) and the distance she drives west (34), which equals the total distance she drives (94).
To find the value of x, subtract 34 from both sides of the equation:
x = 94 - 34
Simplifying the expression, we have:
x = 60
Therefore, Mrs. Lopez drives 60 miles north.
The completed number sentences are:
60 + 34 = 94 and 94 - 34 = 60.
