Answer:
[tex]\sf f^{-1}(x) = \dfrac{x}{2}+4[/tex]
Step-by-step explanation:
A function is given to us and we need to find the inverse of the function in slope intercept form . The given function is ,
[tex]\sf\implies f(x) = 2x - 8 [/tex]
Let us assume that y = f(x) , so that ,
[tex]\sf\implies y = 2x - 8 [/tex]
Now interchange the positions of x and y , we have ,
[tex]\sf \implies x = 2y - 8[/tex]
Solve for y in terms of x ,
[tex]\sf \implies 2y = x + 8 \\\\\sf\implies y =\dfrac{x}{2}+4 [/tex]
This is the inverse of the function in slope intercept form. Now we can replace this y with f-¹(x) , as ,
[tex]\sf \implies \boxed{\pink{\frak{f^{-1}(x) = \dfrac{x}{2}+4}}}[/tex]

B) $1.25
Step-by-step explanation:
1. First, let's take two points. In this case, we're going to take (4,5) and (8,10). We took 2 points, so we can verify the unit rate/cost per pound of pineapple.
2. To find the cost per pound of pineapple, we have to divide the cost (the y-coordinates) by the pound (x-coordinates)
5 ÷ 4 = 1.2510 ÷ 8 = 1.253. Now, since we can verify with 2 coordinates that the cost per pound is $1.25, the answer is B) $1.25.

Answers
The question is an illustration of inequalities and mathematical operations
The amount between $2 and $10 is $8
The amount between $10 and $20 is $10
$100 is greater than $50
(a) Amount between $2 and $10.
The amount is calculated as:
Hence, the amount between $2 and $10 is $8
(b) Amount between $10 and $20.
The amount is calculated as:
Hence, the amount between $10 and $20 is $10
(c) Amount greater than $50.
An amount greater than $50 is an amount that have an higher value.
Take for instance: $100
$100 is greater than $50, because it has a higher value.

Answers
Answer:
g(x)=3
Step-by-step explanation:
Answer:
26
Step-by-step explanation:
g(x) = 3x-1
f(x)= x+5
g(f(4)
plug 4 into f
f(4)
now apply x+5
f(4)=4+5=9
plug 9 into g
g(9)
now apply 3x-1
g(9)=3(9)-1
3 ×9= 27
27-1=26
hence the answer is 26

Find the elapsed time of 8:45AM to 1:10 PM
Answers
Answer:
the answer would be 11 hours and 25 minutes
Step-by-step explanation:
Answer:
4.42 hours
The reason why is by adding, 8:45 can round up to 9, and 1:10 can round down to 1, this make it simpler. 8:45+15 1:10-10
9AM to 1PM
9AM+3=12PM, add 1 and you get 1 pm=4 hrs, add 15+10, and you get somewhere close to it.

At a movie theater, there were 7 kids
for every 2 adults. If kids tickets cost $5
and adult tickets cost $8, how much
money did the theater make if there
were 54 people in the theater?
Answers
Answer:
$306
Step-by-step explanation:
Adult cost = no of adult × adult cost
no of adult = 12
adult tickets cost = $8
= 12 x $8
= $96
kids cost = no of kids x kids tickets cost
no of kids = 42
kids tickets cost = $5
= 42 x $5
= $210
total sales for the theatre =$96 +$210
= $306
