Is the equation -2(4-x) = 2x+8 an identity?

Answer:

Choice 1
It is a one to one function.

Appears to be a cubic function

Step-by-step explanation:

In Δ SZU, UJ = 9, VI = 3 , and ZT = 18 then the value of SJ = 6.

The triangle's centroid is the point where the three medians intersect. According to the centroid theorem, the centroid is 23 times the distance from each vertex to the midpoint of the opposite side.

The centroid has the unique property that the distance from a vertex to the centroid is twice that of the distance from the centroid to the midpoint of the side opposite that vertex for each median. In addition, the three medians of a triangle divide the triangle into six equal-area regions.

Given: In Δ SZU, UJ = 9, VI = 3 , and ZT = 18 .

Since ZV ≅ VU, Y is the midpoint of UZ and SV is a median of Δ ZSU. Similarly, points Y and T are also midpoints of SZ and SU, respectively, so YU and ZT are also medians. Therefore, point J is the centroid of

Δ ZSU and, according to the Centroid Theorem, SJ is 2/3 of SV.

SJ = 2/3 (SV)

= 2/3 (SJ + VJ)

simplifying the above equation, we get

(3SJ/2) - SJ = VJ

SJ/2 = 3

SJ = 6

Therefore, the value of SJ = 6.

The slope of the line that contains the given points E(5,4), F(8,1) is -1.

It is given in the question that the line contains the points E(5,4) and F(8,1).

We know that:-

The formula to find the slope of a line that contains points (a,b) and (c,d) is given by:-

m = (d-b)/(c-a)

Here, we have

m = slope of the line

(a,b) = (5,4)

(c,d) = (8,1)

Hence, putting the values of (a,b) and (c,d) , we get

Slope of the line that contains the given points E(5,4), F(8,1) is given by:-

an=a1+d(n−1) by applying this formula next term of the arithmetic sequence is 8.

See the pattern

2-0 = 2

4-2 = 2

By this we conclude that next term is not 8.

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.

Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.

An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

The given parameters are:

2011-2012:

2012-2013:

The mean is calculated as

Mean = Sum/Count

So, we have

2011 - 2012 mean = (61.1 + 51.9 + 53.6 + 56.5)/4

Evaluate

2011 - 2012 mean = 55.8

Also, we have

2012 - 2013 mean = (64.2 + 56.8 + 48.3 + 55.1)/4

Evaluate

2012 - 2013 mean = 56.1

The difference in these mean values are

Difference = 56.1 - 55.8

Kareem has 7 more strips of wood siding than vinyl siding.

What is a siding?

A siding is a brief railroad track with one or both ends opening into the main track, used to switch one of two meeting trains until the other has passed. Or a siding is any of a number of different forms of weatherproof face for frame buildings, made up of individual sections fastened together as shingles, plain or shaped boards, various sheet metal components, or other composition materials.

Number of vinyl siding strips = 2623/313 = 8.38 ≈ 8 strips

Number of wooden siding strips = 3334/214 = 15.57 ≈ 15 strips

Therefore, extra strips of wooden siding = 15 - 8 = 7 strips

Based on the angles addition postulate, m∠UVW = 140°.

The angles addition postulate says that two smaller angles that is composite of a larger angle can be added together to give the measure of the larger angle.

Based on the angle addition postulate, the following equation that can be used to solve the problem given is derived below:

measure of angle XVW + measure of angle UVX = measure of angle UVW

Given the following:

measure of angle UVX = 76°

measure of angle XVW = 64°

This statement states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

This is a right-angled triangle which means that the missing length can be solved using the Pythagorean theorem:

c² = a² + b²

Where c is the hypotenuse, a and b are the other sides.

Factorize both the denominator and numerator of the rational expression. Remember to write each expression in standard form.

Reduce the expression by cancelling out common factors in the numerator and denominator

Rewrite the remaining factors in the numerator and denominator.

Step-by-step explanation:

Example:

                 Simplify: (x^{2}  + 5x + 4) (x + 5)/(x^{2}  – 1)

Solution:

Factoring the numerator and denominator to get;

⟹ (x + 1) (x + 4) (x + 5)/(x + 1) (x – 1)

Now cancel the common terms.
