Answer:
f(1/x) = (7x+3)/(2x+6)
g(x-2) = √(x² -13x +22)
Step-by-step explanation:
Given equations for f(x) and g(x), you want to find simplified equations for f(1/x) and g(x-2).
F(1/x)Substituting the argument for the variable, we have ...
[tex]f\left(\dfrac{1}{x}\right)=\dfrac{3\cdot\dfrac{1}{x}+7}{6\cdot\dfrac{1}{x}+2}\\\\\boxed{f\left(\dfrac{1}{x}\right)=\dfrac{7x+3}{2x+6}}[/tex]
G(x-2)Substituting the argument for the variable, we have ...
[tex]g(x-2)=\sqrt{(x-2)^2-9(x-2)}=\sqrt{x^2-4x+4-9x+18}\\\\\boxed{g(x-2)=\sqrt{x^2-13x+22}}[/tex]

For DEF, e=52, f=41 and M
For ΔDEF, Where e=52, f=41 and ∠F=48°. Find all the possible ∠E to the nearest degree.
The possible ∠E to the nearest degree is ∠E=70°
Given that,
ΔDEF with e=52 and f=41 sides of the triangle.
Angle ∠F=48°.
We have to find ∠E=?
By using the Law of sine
The relationship between the sides and angles of non-right (oblique) triangles is known as the Law of Sines. It simply states that for all sides and angles of a given triangle, the ratio of the length of a side to the sine of the angle opposite that side is the same.
If triangle ABC are there with sides a, b, and c then Law of sine is
[tex]\frac{a}{SinA} =\frac{b}{SinB} =\frac{c}{SinC}[/tex]
Now, in the given triangle we have e and f sides so we take
[tex]\frac{SinE}{e}=\frac{SinF}{f}\\[/tex]
Substituting the values of e, f and F
We get,
[tex]\frac{SinE}{52}=\frac{Sin48^\circ}{41}\\ SinE=\frac{Sin48^\circ}{41}\times52\\SinE=\frac{52}{41} \times Sin48^\circ\\SinE=1.268\times 0.743\\SinE=0.942\\E=Sin^{-1}(0.942)\\[/tex]
∠E=70°
Therefore, The possible ∠E to the nearest degree ∠E=70°.

than the price of one T-shirt. She sells 50 T-shirts and 40 sweatshirts for a total of $1480. What
is the price of one T-shirt? What is the price of one sweatshirt?
The price of the T-shirt is $ 12
The price of the Sweatshirt is $ 22
Let the Price of a T-shirt is $x, then the Price of a Sweatshirt is $(x+10)
In The Given Question, 50 T-shirts and 40 Sweatshirts are sold at $1480
Then,
50x + 40(x+100) = 1480
50x + 40x + 100 =1480
90x + 400 = 1480

A price is the amount of money that is (often not negatively) exchanged from one party to another in exchange for their goods or services. The cost of production may go by another name in some circumstances. If a product is classified as a "good" in a commercial exchange, its price is most likely to be referred to as such. However, there will be alternative titles for this thing if it is a "service." For instance, the graph at the bottom will display various circumstances.

A numerical expression to represent the greatest total number of fish that could be in both aquariums is Number in Tiger barb + number in giant danios.
The Greatest number of fishes that could be in both aquariums is 14.
We are given that;
Tiger barbs = 30 gallon aquarium
Giant danios = 20 gallon aquarium
Tiger barb = volume / length
Tiger barb = 30 / 3
Tiger barb = 10 fishes
Giant danios = volume / length
Giant danios = 20 /5
Giant danios = 4 fishes
Numerical expression is:
Number in Tiger barb + number in giant danios
= 10 + 4 = 14
Therefore, the correct numerical expression that represents the greatest total number of fish that could be in both aquariums is Number in Tiger barb + number in giant danios.

We get that the solution for this inequalities will be x ≤ - 4.5.
We are given the inequalities:
- 2 x - 3 ≥ 6 or 3 ( x - 4 ) < - 6
For - 2 x - 3 ≥ 6:
Add 3 to both sides:
- 2 x - 3 + 3 ≥ 6 + 3
- 2 x ≥ 9
Divide both sides by - 2
- 2 x / - 2 ≤ 9 / - 2
x ≤ - 4.5
For 3 ( x - 4 ) < - 6:
Divide both sides by 3
x - 4 < - 6
Add 4 to both sides:
x - 4 + 4 < - 6 + 4
x < - 2
We get
x ≤ - 4.5 or x < -2

A car is traveling at 55 miles per hour. Use dimensional analysis to convert
the car's speed to feet per minute.
5,280 feet in 1 mile?
The car's speed to feet per minute is 80.67ft per second.
What is speed?
Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.Speed is a way to gauge how rapidly something is happening, moving, or moving swiftly. The speed of a car being driven at 45 mph serves as an illustration. A person cleaning a room in 10 minutes is an illustration of speed. Speed can be compared to how swiftly a jaguar moves.1 mile = 5280 feet
so 55 miles = 55*5280 = 290,400ft
there are 60 seconds in 1 minute and 60 minutes in 1 hour
so 1 hour = 60*60 = 3600 seconds
55mile/1hour = 290400ft/3600 seconds = 80.67ft per second

Select all of the following graphs which represent y as a function of x?
Using the concept for a relation to represent a function, it is found that graphs 2, 3, 4 and 5 are functions.
When does a relation represents a function?A relation represents a function when it value of the input is associated to only one value of the output.
On a graph, it means that each value of x has only one equivalent value of y, that is, there are no vertically aligned points.
In this problem, we have that:
The first graph, which maps the circle is not a function, as there are multiple values of x associated with two values of y, hence generating vertically aligned points.The last graph, below the constant line, also has values of x such as x = 0 mapped to two values of y(y = 1 and y = -2 for x = 0), hence it also is not a function.All the other graphs are functions.

What is substitution method:The substitution technique is a mathematical approach for solving simultaneous linear equations. The value of one variable with one equation is substituted in the second equation, as the name implies.
According to the given information:The ratio of 1:2 indicates that there is one skier for every two snowboarders.
Let S stand in for the skier.
B should symbolize the snowboarder.
This condition is equivalent to = 1:2 = S:B.
Alternatively, 2S = B.
B - S = 1250
2S - S = 1250
Applying substitution method.
s = 1250
B = 2S = 2(1250) = 2500

write an equation for the line through the point (-7,-4) and parallel to the line y=8x-4 in point-slope form
The equation for the line through the point (-7,-4) and parallel to the line y = 8x - 4 in point-slope form is y = 8x + 52
How to determine the equation of the second line?The first equation is given as
y = 8x - 4
The slope of the above equation is
m = 8
Parallel lines have equal slope
So, the slope of the other line is
m = 8
The equation is then calculated as
y = m(x - x1) + y1
Where
m = 8
(x1, y1) = (-7, -4)
So, we have
y = 8(x + 7) - 4
Expand
y = 8x + 56 - 4
Evaluate the difference
y = 8x + 52
Hence, the equation for the line through the point (-7,-4) and parallel to the line y = 8x - 4 in point-slope form is y = 8x + 52
