Step-by-step explanation:
If we have f(x) and it's inverse, and we compose them
we will get
[tex]f {}^{ - 1} (f(x) = x[/tex]
So here we compose
[tex]( \frac{1}{ \frac{1 + x}{x} - 1} )[/tex]
[tex]( \frac{1}{ \frac{1}{x} + 1 - 1} [/tex]
[tex] \frac{1}{ \frac{1}{x} } [/tex]
[tex]x [/tex]
So the composition is x, so they are inverses.
ABC has side lengths that are each equal to
1 unit. Is there another triangle with the
same side lengths but different angles?

5. A video game console at Games Galore
normally costs $399.50, but all consoles are
marked down by 20% this week. What is the
price of a video game console this week?
Answer:
$319.60
Step-by-step explanation:
Normal Game console cost : $399.50
Discount: %20 (0.20)
$399.50×0.20= $79.90
Total cost of discount $79.90
$399.50-$79.90= $319.60
New cost after Discount= $319.60

In a 51-inch television, the length of the screen's diagonal is 51 inches. If the screen's height is 25 inches,
what is the width? Round your answer to the nearest tenth of an inch.
Answer:
44.452
Step-by-step explanation:
Using the Pythagorean theorem you can use:
51^2 = 25^2 + w^2
2601 = 625 +w^2
w^2 = 1976
w = 44.452
Answer:
The width is 44.5in.
Step-by-step explanation:
25^2 + b^2 = 51^2
625 + b^2 =2601
b^2= 2601-625=1976
Square root it (1976)

What is the value of the expression 3(x+19)-25/5 if x=15
Hey there!
3(x + 19) - 25/5
= 3(15 + 19) - 25/5
= 3(15) + 3(19) - 25/5
= 45 + 57 - 25/5
= 45 + 57 - 5
= 102 - 5
= 97
OR
3(x + 19) - 25/5
= 3(15 + 19) - 25/5
= 3(34) - 25/5
= 102 - 25/5
= 102 - 5
= 97
97 = 97 ☑️
Therefore, your answer is: 97

Answer:
Value of expression = 97Step-by-step explanation:
In the question we have given an expression that is 3 ( x + 19 ) - 25/5 and value of x is equal to 15 .
And we are asked to find the value expression when value of x is 15 .
Solution : -
[tex] \longmapsto \: 3( x+ 19) - \cancel{\frac{25}{5} }[/tex]
Step 1 : Substituting value of x in given expression and cancelling 25 by 5 :
[tex] \longmapsto \: 3(15 + 19) - 5[/tex]
Step 2 : Solving parenthesis by adding 15 and 19 :
[tex] \longmapsto \: 3(34) - 5[/tex]
Step 3 : By multiplying 3 with 34, we get :
[tex] \longmapsto \: 102 - 5[/tex]
Step 4 : Subtracting 5 from 102 :
[tex] \longmapsto \: \red{ \boxed{ \frak{97}}}[/tex]

The rectangle of the rectangle is shown 44m squared. Find out the missing length of x
Answer:
12 m
Step-by-step explanation:
3 ⅔
= 3 + 2/3
= 9/3 + 2/3 { LCM = 3 }
= ( 9 + 2 ) / 3
= 11/3
In the diagram,
Length ( l )= x m
Breadth ( b ) = 3 ⅔ m = 11/3 m
Given that area of the rectangle = 44 m²
Formula : -
Area of the rectangle = lb
lb = 44
x * 11/3 = 44
x = ( 44 * 3 ) / 11
x = 4 * 3
x = 12 m
Therefore,
the missing length = 12 m

Our competitor struggled to sell 350 products & we sold 46% more than they did
Answer:
The quantity we sold more than the competitors is 161.
What are percentages?
Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred.
How much more did we sell?
Quantity sold more = percentage sold more x number sold by competitors
46% x 350
0.46 x 350=161.
Find the point on the line -5x + 7y - 4 = 0 which is closest to the point (2,3).
Answer:
(x, y) = (2 35/74, 2 25/74)
Step-by-step explanation:
The closest point on the line to the given point will be the point of intersection of the given line and a perpendicular through the given point.
__
A line perpendicular to ax+by+c=0 that goes through point (h, k) can be written as ...
b(x-h) -a(y-k) = 0
For the given line and point, the perpendicular line will be ...
7(x -2) +5(y -3) = 0
7x +5y -29 = 0
Using the cross-multiplication method, we can find the solutions to the system of equations consisting of these two lines. It will be ...
-5x +7y -4 = 07x +5y -29 = 0Δ = (-5)(5) -(7)(7) = -74
Δx = (7)(-29) -(5)(-4) = -183
Δy = (-4)(7) -(-29)(-5) = -173
x = Δx/Δ = -183/-74 = 2 35/74 ≈ 2.4730
y = Δy/Δ = -173/-74 = 2 25/74 ≈ 2.3378

Can you find the area and explain how you got the area
Answer:
102cm^2 - hope this helps
Step-by-step explanation:
find the area of the rectangle first in the middle
which equals 6 x 13 = 78cm^2
then find the traingles on the side
(6 x 4) / 2 = 12
there are 2 traingles so it would be 12 + 12 = 24
so all together the area would be 78 + 24 = 102cm ^2
