Note: Your function is missing some information. It seems your function is
[tex]f\left(x\right)=\frac{-3}{x}+7[/tex].
So, I am solving the question based on the function [tex]f\left(x\right)=\frac{-3}{x}+7[/tex], because it would still solve your query.
Answer:
Please see the explanation.
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=\frac{-3}{x}+7[/tex]
A function g is the inverse of a function f for y = f(x), x=g(y)
[tex]y=\frac{-3}{x}+7[/tex]
Replace x with y
[tex]x=\frac{-3}{y}+7[/tex]
solve for y
[tex]y=-\frac{3}{x-7}[/tex]
so the inverse of [tex]f\left(x\right)=\frac{-3}{x}+7[/tex] will be:
[tex]f^{-1}\:\left(x\right)=-\frac{3}{x-7}[/tex]
Finding the domain of [tex]f^{-1}\:\left(x\right)=-\frac{3}{x-7}[/tex]
As we know that domain is the set of the possible input values where the function is defined.
so the function domain must be: [tex]x<7\quad \mathrm{or}\quad \:x>7[/tex]
Therefore,
[tex]\mathrm{Domain\:of\:}\:-\frac{3}{x-7}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x<7\quad \mathrm{or}\quad \:x>7\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:7\right)\cup \left(7,\:\infty \:\right)\end{bmatrix}[/tex]

Solve the following proportion: x+3/2 equal to 7/8
Step-by-step explanation:
x+ 3/2 = 7/8
3/2 is equivalent to the fraction 12/8
Since the two fractions have common denominators, you can do.
x= 7/8 - 12/8
x=(-5/8)

X, Y and Z form the vertices of a triangle, where ∠ YXZ = 68°, XY = 7.3m and XZ = 8.3m. Calculate the area of the triangle. Round your answer to 1 DP.
Answer: Area = 28.2m²
Step-by-step explanation: The triangle YXZ is shown in the figure below.
Area of a triangle is calculated by the formula:
[tex]A=\frac{1}{2} (base*height)[/tex]
According to the figure, the base of this triangle is b = 8.3m.
Height is a perpendicular line created from one side and intersecting the opposite angle.
To determine the height, use trigonometric relations to angle 68:
[tex]sin(68)=\frac{h}{7.3}[/tex]
h = 7.3*sin(68)
h = 7.3*0.93
h = 6.8
Now, area of triangle YXZ is
[tex]A=\frac{1}{2} (8.3*6.8)[/tex]
A = 28.2
Area of triangle YXZ is 28.2m².

Together, teammates Pedro and Ricky got 2675 base hits last season. Pedro had 277 more hits than Ricky. How many hits did each player have?
Answer:
1199 for ricky, 1476 for Pedro
Step-by-step explanation:
2675-277=2398
2398 / 2 = 1199
each player had 1199 bases, pedro however, had 277 more bases than ricky
1199 + 277 = 1476
By solving a system of equations, we conclude that Ricky has 1,199 base hits, and Pedro has 1,476 base hits.
How many hits did each player have?Let's define the variables:
P = base hits of Pedro last season.R = base hits of Ricky last season.Then we have that the total number of base hits last season is 2675, so we have:
P + R = 2675
We also know that Pedro has 277 more hits than Ricky, then:
P = 277 + R
To solve these equations, we can replace the second equation into the first one:
P + R = 2675
(277 + R) + R = 2675
2*R = 2675 - 277 = 2,398
R = 2,398/2 = 1,199
So we conclude that Ricky has 1,199 base hits, and Pedro has 1,476 base hits.

The perimeter of a rectangular garden is 338 m.
If the width of the garden is 74 m, what is its length?
Answer:
l=95
Step-by-step explanation:
Perimeter is all the sides add up. So the equation if you know two of the sides, it should be: 338=(2*74)+(2*l)
Answer:
Step-by-step explanation:
the perimeter is 2w plus 2l
so 338 = 74(2)+2l
338 = 148+2l
190=2l
l=95
your length would be 95 m

Edan buys 3 tickets to a concert. When the delivery charge of $7.75 per order is added to the cost of the tickets, the total cost is $70.75. A) Create an algebraic equation for this problem. Use the equation to determine the cost of each ticket. Verify your solution. B) Olivia is Edan's cousin. Olivia has asked Edan to purchase tickets for her friends as well. Edan has now purchased 6 tickets in total. Use an algebraic equation to determine the total cost to Edan? C) Olivia has come down with the flu, and her friends no longer want to attend the concert. Edan is thinking of selling the 6 tickets she bought. Her goal is to earn $100 after selling the tickets. Using the equations from part a) and b), how much should Edan sell each ticket for, if she wants to make a profit of at least $100?
Answer:
a) $21
b) $133.75
c) $233.75
Step-by-step explanation:
Edan buys 3 tickets to a concert. When the delivery charge of $7.75 per order is added to the cost of the tickets, the total cost is $70.75.
A) Create an algebraic equation for this problem. Use the equation to determine the cost of each ticket. Verify your solution.
Let the number of tickets be represented by x
The equation is:
3x + 7.75 = 70.75
3x = 70.75 - 7.75
3x = 63
x = 63/3
x = $21
Each ticket cost $21
B) Olivia is Edan's cousin. Olivia has asked Edan to purchase tickets for her friends as well. Edan has now purchased 6 tickets in total. Use an algebraic equation to determine the total cost to Edan?
1 ticket cost = $21
Let the number of tickets be represented by x
Hence, the equation is
21x + $7.75
21 × 6 + $7.75
= 126 + $7.75
= $133.75
C) Olivia has come down with the flu, and her friends no longer want to attend the concert. Edan is thinking of selling the 6 tickets she bought. Her goal is to earn $100 after selling the tickets. Using the equations from part a) and b), how much should Edan sell each ticket for, if she
Profit = Selling price - Cost Price
Cost price = $133.75
Profit = $100
Selling price = Cost price + Profit
Selling price = $133.75 + $100
= $233.75
