Answer:
(1/2(2x+14)-7) = 1x+7-7= x g(f(x))= 2(1/2x-7)+14= x-14+14= xWe have the result being two variables of linearity hence they are not inverses. In order to be inverses they should have had switched notations, ie: -x vs x9514 1404 393
Answer:
A: (f∘g)(x) = x
B: (g∘f)(x) = x
C: the functions are inverses
Step-by-step explanation:
A: (f∘g)(x) = f(g(x)) = f(2x +14)
= 1/2(2x +14) -7 = x +7 -7 = x
(f∘g)(x) = x
__
B: (g∘f)(x) = g(f(x)) = g(1/2x -7)
= 2(1/2x -7) +14 = x -14 +14 = x
(g∘f)(x) = x
__
C: When a function is operated on by its inverse, then original argument value is restored. That is the case for functions f and g, so the two functions are inverses.

Which of the following is equivalent to 2 · (4 · 3)?
A. 2 + (4 + 3)
B. 2 x (6 x 4)
C. (2 x 4) x 3
D. 8
Answer:
C. (2 x 4) x 3

Area of circle = π(5²) = 25π m²
Area of total = 100 - 25π = 21.46018366

10. Write an expression in simplified form to
represent the area of the trapezoid.
Answer:
48[tex]x^{7}[/tex]y
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases , then
A = [tex]\frac{1}{2}[/tex] × 4[tex]x^{5}[/tex] × (9x²y + 15x²y )
= 2[tex]x^{5}[/tex] × 24x²y
= 48[tex]x^{7}[/tex]y
The simplified expression for the area of the trapezium is 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex].
What is trapezium?A trapezium is a quadrilateral with four sides where two sides are parallel to each other.
We have,
Trapezium.
Height = 4[tex]x^5[/tex]
Parallel sides are 15x²y and 9x²y.
The area of the trapezium.
= 1/2 x h x ( sum of the parallel sides )
Now,
Area of the trapezium.
= 1/2 x 4[tex]x^5[/tex] x (15x²y + 9x²y)
= 2[tex]x^5[/tex] x (15x²y + 9x²y)
= 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex]
Thus,
The area of the trapezium is 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex].

Louis makes a model of a plane.
The wingspan of the model is 50 centimetres.
The wingspan of the real plane is 80 metres.
Work out the scale of the model.
Give your answer in the form 1:n
Answer:
1 : 1.6
For every centimeter on the model, it is 11.6 centimeters on the real plane
Step-by-step explanation:
The required value of the scale of the model in the form of 1:160.
Given that,
The wingspan of the model is 50 centimeter,
The wingspan of the real plane is 80 meter.
We have to determine,
The scale of the model and give your answer in the form 1 : n.
According to the question,
The wingspan of the model = 50 centimeter [tex]= \frac{50}{100} = 0.5m[/tex]
The wingspan of the real plane is 80 meter.
The ratio of the scale = 1:n
Therefore,
The equation of proportion is,
[tex]\frac{wingspan \ of \ the \ model}{wingspan\ of \ the \ palne} = \frac{1}{n}[/tex]
Putting all the values in the equation,
[tex]\frac{0.5}{80} = \frac{1}{n} \\\\n = \frac{1 \times 80}{0.5} \\\\n = 160[/tex]
The value of n = 160.
Hence, The required value of the scale of the model in the form of 1:160.

Write an inequality relating NM and NL-
NM < NL
NM<_ NL
NM > NL
NM>_ NL
Answer:
NM > LN
Step-by-step explanation:
Here, we want to write an inequality
we should beat it in mind that, the greater the angle that a side of a triangle faces, the greater its length will be relatively
as we can see, the side NM faces the greater angle of 83, relative to the side LN that faces the angle of 56;
So we can conclude that;
NM > LN

Which graph represents the function f(x) = 4x
Answer:
[tex]\boxed{\textsf{ The required graph of y = 4x will be a straight line passing through the origin . }}[/tex]
Step-by-step explanation:
Here we need to plot the graph for the function given to us . The function is ,
[tex]\sf \implies f(x)= 4x [/tex]
In order to plot a graph let us assume that ,
[tex]\sf\implies y = f(x) [/tex]
Hence we now get , that ,
[tex]\sf\implies y = 4x [/tex]
Now let's find out some values of x and y taking which we will plot the graph .
• So , firstly let , x = 0 then y will be equal to 4*0 = 0 . Hence we got one coordinates as (0,0) .
• Secondly let x = 1 , then y will be equal to 4*1 = 4 . Hence we get the third coordinate as (4,0) .
• Thirdly let us take that x = 0.5 then y will be equal to 4*0.5 = 2 . Hence we got the third coordinate as ( 0.5 , 2 )
• Fourthly let x = -0.5 then y will be equal to 4*-0.5 = -2 . Hence the fourth coordinate will be (-0.5 , -2)
Now when we plot it's graph taking suitable scale then it will look something like that as shown in attachment .
For the graph of y = 4x kindly refer to the attachment :) .
