The correct expression will be ( x- 4 ). So option B is right.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The expression will be solved as:-
E = ( - √(x-4))²
The product of two minuses is positive and the product of the same square root numbers will be the number so the equation will become.
E = -√(x-4) x -√(x-4)
E = x - 4
Therefore the correct expression will be ( x- 4 ). So option B is right.

F(x) =x+4/3 and g(x) = 3x – 4 Verify that the functions below are inverses by showing that (f o g)(x) = x and (g o f)(x) = x.
Answers
Answer:
The answer is below
Step-by-step explanation:
A composite function is a function which is placed inside another function, this type of function can be calculated by substituting one function into another function.
If two functions g(x) and f(x) are inverses, then each will reverse the effect of the other. That is, (f○g)(x)=f(g(x))=x and (g○f)(x)=g(f(x))=x.
Given that F(x) =(x+4)/3 and g(x) = 3x – 4
a) (f o g)(x) = f[g(x)]
= f(3x - 4)
= [(3x - 4) + 4]/3
= [3x - 4 + 4]/3
= 3x / 3
= 3
b) (g o f)(x) = g[f(x)]
= g[(x + 4)/3]
= 3(x + 4)/3 - 4
= x + 4 - 4
= x
We can see that (f o g)(x) = (g o f)(x) = x. Hence the functions are inverse functions.
the ratio of two supplementary angles is 3:9 what is the measure of the larger angle
Answers
Answer:
135
Step-by-step explanation:
Ratio = 3 : 9
Angles are : 3x , 9x
3x + 9x = 180 {supplementary angles}
12x = 180 {divide both side by 12}
x = 180/12
x = 15
Larger angle = 9x = 9*15 = 135

A tent company makes one kind of tent that is shaped like a triangular prism. The approximate dimensions of the tent are 30 times 1/2 plus 30 times 1/2 plus 49.5 plus 49.5 plus 54 equals?
Answers
Answer:
The answer is below
Step-by-step explanation:
A triangular prism is a polyhedron (three dimensional shape) made up of two equal triangles, two equal rectangle and a base rectangle.
The total surface are of a triangular prism is given as:
A = bh + 2ls + lb
where b is the base of the triangle, h is the height of the triangle, l is the length of the base rectangle and s is the length of the slant side of the triangle.
Given that:
b = 6 ft, s = 5.5 ft, h = 5 ft, l = 9 ft.
Therefore:
A = (6 * 5) + 2(9 * 5.5) + (9 * 6) = 183 ft²
Therefore 183 ft² of fabric is needed to make the tent

How would you do this maths question?
Answers
Answer:
Step-by-step explanation:
First you take the 142+B=180
because those 2 are supplementary
B=38
and you see the 2 lines on the 2 sides that means those two sides are equal to each other and the angles corresponding with them are also equal to each other.
and a triangle= 180 degrees
A and E are the same so A=E
180-B(38)= 142
and because A=E you do 142/2= 71
and now that you have A and E you don't need A or B for the last part so
E+(x)=180 because those two angles are supplementary.
and E is 71 so...
71+(x)=180 ---------180-71=x

Answers
Answer:
y = -8/3x - 11
Step-by-step explanation:
(-6, 5) and (-3, -3)
Slope:
m=(y2-y1)/(x2-x1)
m=(-3-5)/(-3+6)
m=(-8)/3
m= -8/3
Slope-intercept:
y - y1 = m(x - x1)
y - 5 = -8/3(x + 6)
y - 5 = -8/3x - 16
y = -8/3x - 11

Answer: y- 2 = -1/2(x - 2)
Step-by-step explanation:
We need to rewrite it as y=mx+b.
x - 2y = 4
2y = - x + 4
y = -1/2x + 4/2
y = -1/2x + 2
The slope for x - 2y = 4 is -1/2.
In addition, the slope of two parallel line would be the same, the slope of the line that pass through the point (2,2) would be -1/2.
y- y1 = m(x- x1)

Answer:
77 5/8
Step-by-step explanation:
a) Multiply the whole number 6 by the denominator 4. Whole number 6 equally 6 * 4/4
= 24/4
b) Add the answer from the previous step 24 to the numerator 3. New numerator is 24 + 3 = 27
c) Write a previous answer (new numerator 27) over the denominator 4.
Conversion a decimal number to a fraction: -11.5 = -115/10
= -23/2
a) Write down the decimal -11.5 divided by 1: -11.5 = -11.5/1
b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
-11.5/1
= -115/10
c) Simplify and reduce the fraction
-115/10
= -23 * 5/2*5
= -23 * 5/2*5
= -23/2
Multiple: 27/4
* (-11.5) = 27 · (-23)/4 times5
= -621/8
