An invertible function is represented by the values in the table.
Which graph shows the inverse of this function?
Answer:
Graph B
Step-by-step explanation:
Because th inverse fuction is f^-1(x), you basicaly swap the numbers, all x valuese would equal y.
In this exercise we have to identify the treated inverse function and the graph that corresponds to it, so we have that what corresponds to this is:
Graph B corresponds to the given function.
In this way, the inverse function corresponding to:
[tex]f^{-1}(x)[/tex]
Because th inverse fuction is f^-1(x), you basicaly swap the numbers, all x valuese would equal y. So we will have that the graph that correctly corresponds to this function is graph B.

parker was able to pay 56% of his tuition with his scholarship .The remaining $6,057.35 he paid for with a student loan . What was the cost of parkers tuition ?
Answer:
$13,766.70
Step-by-step explanation:
Since he paid 56% with the scholarship, that means $6,057.35 is 44% of the total tuition
To find the total cost of tuition, divide 6,057.35 by 0.44
6,057.35/0.44
= 13766.70
So, the cost of Parker's tuition was $13766.70

Law of Cosines : c2 = a2 + b2 - 2ab cos C
Enter
Answer:
[tex]C=69.1^{\circ}[/tex]
Step-by-step explanation:
The Law of Cosines is given as:
[tex]c^2=a^2+b^2-2ab\cos C[/tex].
Plugging in given values, we get:
[tex]16^2=8^2+17^2-2\cdot 8\cdot 17\cdot \cos C,\\\cos C=\frac{-97}{-272},\\C=\arccos(\frac{97}{272}),\\C=\fbox{$69.1^{\circ}$}[/tex].
The graph shows how a motorboat travels around a lake. What does the graph most likely show?
The speed of the boat increases steadily for 10 minutes and travels at a constant speed after 10 minutes.
Option D is the correct answer.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
We have,
The x-axis can be assumed as 10 minutes for each unit.
Now,
From the graph, we see that the speed is steadily increasing as the time increases from x= 0 to x = 10.
From x = 10, the line on the graph is horizontal this means, the speed is constant.
Thus,
The speed of the boat increases steadily for 10 minutes and travels at a constant speed.

Two students are reading a book. Keith reads 6 pages a day. Tameka reads 5 pages a day, but he starts sooner and has already read 15 pages. Write a system of equations to represent the situation, using d for days and p for pages.
Answer:
P = 6d ; P = 5d + 15
Step-by-step explanation:
Given that :
Keith = 6 pages per day
Tameka = 5 pages per day
Tameka has already read 15 pages
If d = Number of days ; p = pages read
Keith :
Pages read, p = pages read per day * Number of days, d
P = 6d
Tameka :
Pages read, p = (pages read per day * Number of days, d) + pages read already
P = 5d + 15
The system of equations to represent the number of pages read per day by Keith and Tameka, using d for days and p for pages are,
[tex]\\P=6d[/tex]
[tex]P=5d+15[/tex]
What is the system of equation?A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.
Two students are reading a book. Keith reads 6 pages a day. Equation for Keith, where d for days and p for pages can be given as,
[tex]P=6\times d\\P=6d[/tex]
Tameka reads 5 pages a day, but he starts sooner and has already read 15 pages. The equation for Tameka, where d for days and p for pages, can be given as,
[tex]P=5\times d+15\\P=5d+15[/tex]
Hence, the system of equations to represent the number of pages read per day by Keith and Tameka, using d for days and p for pages are,

Find the inverse of the function f(x) = 2x - 4.
Answer:
f⁻¹(x) = 1/2 x + 2
Step-by-step explanation:
f(x) = 2x - 4 y=2x - 4
swap x and y: x = 2y - 4
solve y: 2y = x + 4
y = 1/2 x + 2
Inverse notation: f⁻¹(x) = 1/2 x + 2

How many solutions
Answer:
I solution; x=8
Step-by-step explanation:
You have to solve for x by simplifying both sides of the equation and then isolating the variable
3(x+2)= 2x+14
Distributive Property
3x+6=2x+14
Isolate the variable
3x+6-6=2x+14-6 which is 3x=2x+8
3x-2x=2x-2x+8
x=8

6. Determine the Rate of Change in the graph below.
Answer: slope is 1/2
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
Using the equation slope = y2-y1/x2-x1 we can plug in (-4,-6) as x1 and y1 and (6,-1) as x2 and y2. We than have the equation -1+6/6+4 = slope, doing the math we now have 5/10 or 1/2 which is our rate of change
