Determine whether (a) x = -1 or (b) x = 2 is a solution to this equation

The test of validity is used to determine whether a claim is true or not, based on certain condition(s).

The validity of the given statement is true.

From the question, the given condition is:

Whenever he participates in a race, he is the winner

This can be interpreted as follows:

So, if he is sick; it means that he does not participate in the race and as such he is not the winner.

Hence, the validity of the following statement is true

"Either he participates in the race or he is sick he is not the winner, therefore he is sick​."

Step-by-step explanation:

cost of 1 table=2400/6=rs.400

or ,cost of 1 chair=2400/8=rs.300

now,

cost of 24 tables=24×400=9600

or,cost of 12 chairs=12×300=3600

or,

may be the question is,

6tables + 8 chairs= 2400

24 tables + 12 chairs=?

solution,

cost of 1 tables=rs.200

cost of 1 chair=rs.150

now,

cost of 24 tables=200×24=4800

cost of 12 chairs=150×12=1800

so, ans= 4800+1800=6600

Answer:

Rs.13200

Step-by-step explanation:

cost of 6 tables=Rs.2400

or,

cost of 8 chair=Rs.2400

cost of 1 table=2400/6

                      =Rs.400

cost of 1 chair=2400/8

                      =Rs.300

cost of 24 tables=24*400

                            =Rs.9600

cost of 12 chairs=12*300

                         =Rs.3600

total cost of 24 tables and 12 chairs=9600+3600

                                                          =Rs.13200

According to the the video, the Golden Ratio is a figure in mathematics theorized by mathematicians as a value that indicates natures beauty symmetry

[tex]\mathbf{The \ value\ of \ the \ Golden \ ratio \ is \ \phi} = \mathbf{\dfrac{1 + \sqrt{5} }{2} }[/tex]

Good examples of the Golden Ratio in art and architecture is the Great Pyramid of Giza, constructed in 2570 B.C. and the temple of Parthenon for which construction began in 447 BC and the decoration completed in 432 BC

The reason the temple of Parthenon is so interesting is that the temple just like the pyramid were meant to last indefinitely, such that they can only be made to last so long by the deities, as such by building using the Golden Ratio found in nature including the spiral galaxies, is in recognition of nature's beauty which is aesthetically pleasing to the eyes, harmonious, and maybe preservative

2. The common presence of the Golden Ratio in the universe can be seen as both a grand design and a coincidence, however, due to the higher prevalence than random occurrence, it can be taken as a design that can be observed in nature

3. The topic helps reinforce the belief in the application of math to daily life, because it is a good portrayal of how math can contribute to all aspect of human life

Answer:

(-6,6)

Step-by-step explanation:

A set S has four members if there are six subsets of it, each with two members.

The combination formula, which is given by: can be used to determine the total amount of subsets with two members each.

[tex]^nC_k= \dfrac{n!}{(k!(n-k)!)}[/tex]

There are 6 subsets in this situation, each with 2 members.

So, [tex]^nC_2[/tex] = 6

Simplifying the equation:

n! / (2!(n-2)!) = 6

n(n-1) / (2 x 1) = 6

n(n-1) / 2 = 6

n(n-1) = 12

Expanding the equation:

[tex]n^2 - n = 12[/tex]

[tex]n^2 - n - 12 = 0[/tex]

Factoring the quadratic equation:

(n - 4)(n + 3) = 0

When all factors are set to zero and n is calculated:

n - 4 = 0    or    n + 3 = 0

n = 4        or    n = -3

Since n must be a positive integer.

So, n = 4 is the valid solution.

Thus, set S consists of 4 members.

Answer:

no solution

Step-by-step explanation:

5x-3(x-8)=2x-4

Distribute

5x -3x+24 = 2x-4

Combine like terms

2x +24 = 2x-4

Subtract 2x from each side

2x+24-2x = 2x-4-2x

24 = -4

This is not a true statement so there is no solution

Answer:

No Solution

Step-by-step explanation:

5x-3(x-8)=2x-4

1) Distribute:

5x -3x+24 = 2x-4

2) Simplify:

2x +24 = 2x-4

3) Subtract 2x from both sides

2x+24-2x = 2x-4-2x

We are now left with (after simplifying): 24 = -4

Answer: c. y= 2x -3

Step-by-step explanation:

Slope Intercept Form: y= mx +b

m=slope

b= y intercept

the slope is 2 because the line "rises" 2 times and "runs" 1 time

rise/run

2/1

m=2

the y intercept is where the line crosses the (vertical) y-axis

on this graph the line crosses at (0,-3), therefore

b= -3

plug into Slope Intercept Form:

y= mx +b

y= 2x-3

Answer:

Step-by-step explanation:

Diameter = 6 units

Radius = Diameter/2 = 6/2 = 3 units

Taking π=3.14

Circumference = 2(π)(r) = 2(3.14)(3) = 6(3.14) = 18.84 = c

c = 18.84

Area = π(r)^2 = π(3)^2 = 9π =9(3.14) = 28.26 = b

b = 28.26

So,

b + c = 28.26 + 18.84 = 47.1

Answer:

b=6π the unit(cm)

c=18.84 the unit(cm)

b+c=

9+18.84=27.84
