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).

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]

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]

The car's speed to feet per minute is  80.67ft per second.

What is speed?

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

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°.

There are 1250 skiers and 2500 snowboarders bought season passes.

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.

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

B = 2500

There are 1250 skiers and 2500 snowboarders.

Answer:

31/4

Step-by-step explanation:

The Mixed Number 7 3/4 can be changed into the improper fraction 31/4.

step 1: The denominator of the improper fraction will be 4, since the denominator of the original fraction is 4.

to find the improper fraction, multiply the denominator of the original fraction (4) by the whole number (7). 4x7=28 then add the numerator of the original fraction: 28+3=31. This tells you the numerator of the improper fraction will be 31.

The improper fraction is 31/4.

Using the concept for a relation to represent a function, it is found that graphs 2, 3, 4 and 5 are functions.

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.

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

90x = 1480 - 400

90x = 1080

x= [tex]\frac{1080}{90}[/tex]

x = 12

The price of the T-shirt is $ 12 and the Price of the Sweatshirt is $ 22

The price of the T-shirt is $ 12

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.

Step-by-step explanation:

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

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

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
