Step-by-step explanation:

GIVEN:

In order to solve this, you need to isolate the term x on one side of the equation.

First, combine like terms.

[tex]\Longrightarrow: \sf{8x+16x+21=25x+19}[/tex]

Solve.

8x+16x=24x

[tex]\Longrightarrow: \sf{24x+21=25x+19}[/tex]

You have to subtract by 21 from both sides.

[tex]\Longrightarrow: \sf{24x+21-21=25x+19-21}[/tex]

Solve.

[tex]\Longrightarrow: \sf{24x=25x-2}[/tex]

Subtract by 25x from both sides.

[tex]\Longrightarrow: \sf{24x-25x=25x-2-25x}[/tex]

Solve.

-x=-2

Then, you divide by -1 from both sides.

[tex]\Longrightarrow: \sf{\dfrac{-x}{-1}=\dfrac{-2}{-1}}[/tex]

Solve.

Divide the numbers from left to right.

[tex]\sf{\dfrac{-2}{-1}=2 }[/tex]

SOLUTIONS:

[tex]\Longrightarrow: \boxed{\sf{x=2}}[/tex]

I hope this helps. Let me know if you have any questions.

Answer:

[tex]x = 2[/tex]

Given equation:

Combine like terms on the L.H.S and simplify the expression as needed.

Now, rewrite 25x in such a way such that 24x can be repeated on both sides. Clearly, we can rewrite 25x as 24x + x. Then,

Since 24x is being repeated on both sides, we can cancel it.

Finally, subtract 19 on both sides to isolate x.

Therefore, the value of x is 2.

Perimeter:-

Answer:

104 inches

Step-by-step explanation:

A kite has two pairs of consecutive, congruent sides.

Therefore, BC = AB  and  AD = DC

We can use this to determine the values of x and y, and then the perimeter of the kite.

If BC = AB

⇒ 5x = 3x + 12

Subtract 3x from both sides:

⇒ 2x = 12

Divide both sides by 2

⇒ x = 6

If AD = DC

⇒ 11y - 22 = 7y - 6

Subtract 7y from both sides:

⇒ 4y - 22 = -6

Add 22 to both sides:

⇒ 4y = 16

Divide both sides by 4:

⇒ y = 4

As BC = AB  and  AD = DC

⇒ perimeter = 2 (BC + AD)

                     = 2 (5x + 11y - 22)

Substituting found values of x and y:

⇒ perimeter = 2 (5(6) + 11(4) - 22)

                     = 2 (30 + 44 - 22)

                     = 2 (52)

                     = 104 inches

Answer:

See below ~

Step-by-step explanation:

Answer:

Hello! The solution to this linear equation is 0 = 0. To find this solution:

Distribute -

8 - 2(4v+6) = -4 - 8v

8 - 8v - 12 = 14 - 8v

Subtract the numbers -

8 - 8v - 12 = -4 - 8v

-4 - 8v =  -4 - 8v

Rearrange terms -

-4 - 8v = -4 - 8v

-8v - 4 = -4 - 8v

Rearrange terms -

-8v - 4 = -4 - 8v

-8v - 4 = -8v - 4

Add 4 to both sides -

-84v - 4 = -8v - 4

-8v - 4 + 4 = -8v - 4 + 4

Simplify -

-8v - 4 + 4 = -8v - 4 + 4

-8v = -8v - 4 + 4

-8v = -8v

Add 8v to both sides -

-8v = -8v

-8v + 8v = -8v + 8v

Combine like terms and simplify -

-8v + 8v = -8v + 8v

0 = -8v + 8v

0 = 0

The solution is 0 = 0. This is an identity: it is true for all values.

Hope this helps! Have a great day.

We will see that the equation has only one solution, so the correct option is B.

For an equation of the form:

p(x) = C

Where p(x) is an expression that depends on x, and C is a constant.

The solutions are all the values of x that make the equality true.

For our case, we have:

x = -5

Notice that there is only one value of x that makes the equality true, if we replace x by -5 we get:

-5 = -5

So that is the only solution for the equation, then we conclude that the equation has only one solution, and the correct option is B.

The simulation of the customer visit is an illustration of probability

The probability that a customer would visit the coffee shop at least 5 times to win a gift card is  [tex](\frac {11}{12})^{n} - (\frac n{12}) * (\frac {11}{12})^{n - 1} - .......... - ^nC_4 * (\frac 1{12})^4 * (\frac {11}{12})^{n - 4}[/tex]

From the question, we understand that every 12th customer gets a $5 gift card.

This means that the probability that a customer gets a gift card is:

p = 1/12

The probability that a customer would visit the coffee shop at least 5 times to win a gift card is calculated using the following complement rule:

P(x ≥ 5) = 1 - P(x <5)

The equation becomes

P(x ≥ 5) = 1 - P(0) - P(1) - P(2) - P(3) - P(4)

Using the binomial formula

[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]

The equation becomes

[tex]P(x \ge 5) = ^nC_0 * (\frac 1{12})^0 * (1 - \frac 1{12})^{n - 0} - ^nC_1 * (\frac 1{12})^1 * (1 - \frac 1{12})^{n - 1} - .......... - ^nC_4 * (\frac 1{12})^4 * (1 - \frac 1{12})^{n - 4}[/tex]

Simplify

[tex]P(x \ge 5) = (\frac {11}{12})^{n} - (\frac n{12}) * (\frac {11}{12})^{n - 1} - .......... - ^nC_4 * (\frac 1{12})^4 * (\frac {11}{12})^{n - 4}[/tex]

Hence, the estimate that a customer would visit at least 5 times is [tex]P(x \ge 5) = (\frac {11}{12})^{n} - (\frac n{12}) * (\frac {11}{12})^{n - 1} - .......... - ^nC_4 * (\frac 1{12})^4 * (\frac {11}{12})^{n - 4}[/tex]

If the steel market is competitive, firms can produce steel at a constant marginal cost of $100 per ton.

Therefore, the price of steel is $100 per ton, and 100 tons are produced.

Assume that if all the steel companies consolidate into a monopoly, the monopoly’s marginal cost will fall to $70 per ton.

If the market is controlled by a monopoly, the total surplus will be

The demand curve has to be defined the demand curve will be

Remark

The zeros are found either by using the quadratic equation or by factoring and equating the factors to 0. I think factoring is the best and simplest way.

Solution

x^2 - 5x + 6 factors into

(x - 3)(x - 2)

-3 and - 2 must multiply to 6 (they do) -3 * -2 = 6

-3 and -2 must also add to - 5. They do. -3 - 2 = - 5

So the factors are correct.

x - 3  = 0

x - 3 + 3 = 0 + 3

The correct order which shows the standard deviations of the data sets A,B and C in order from greatest to least is C, B, A.

Suppose that

[tex]x_i; \: \: i = 1,2, ... ,n[/tex] are n data values for the given data set.

Then we have: Variance as,

[tex]\sigma^2 = \dfrac{\sum_{\forall x_i} (x_i - \overline{x})^2}{n}[/tex]

As standard deviation is the positive root of variance, thus,

[tex]\sigma = \sqrt {\dfrac{\sum_{\forall x_i} (x_i - \overline{x})^2}{n}}[/tex]

If its sample, we divide by n-1 instead of n

Use data sets A, B, and C to answer the question that follows.

The mean of the set A is,

[tex]\overline{x}_A=\dfrac{25+24+ 25+ 22+ 21+23+ 1}{7}=20.143[/tex]

Similarly, the mean of set B and C is,

[tex]\overline{x}_B=\dfrac{20+ 23+ 25+ 21+ 24+ 22+ 60}{7}=27.857\\\overline{x}_C=\dfrac{20+21+ 20+ 22+ 20+ 24+ 99}{7}=32.286[/tex]

The standard deviation of the set A is,

[tex]\sigma_A = \sqrt {\dfrac{(25-20.143)^2+(24-20.143)^2......+(1-20.143)^2}{7}}\\\sigma_A = 7.936[/tex]

Similarly, the standard deviation of set B and C is,

[tex]\sigma_B = \sqrt {\dfrac{(20-27.857)^2+(23-27.857)^2......+(60-27.857)^2}{7}}= 13.217\\\sigma_C = \sqrt {\dfrac{(20-32.286)^2+(21-32.286)^2......+(99-32.286)^2}{7}}= 27.27[/tex]

The value of standard deviation of set C is the highest while set A is lowest.

⇒Cosec 2 A + ( Cot 2 A )2

⇒Cosec 2 A + ( Cosec 2 A - 1 )2  (  we know : 1 + Cot 2 θ =  Cosec 2 θ )

⇒Cosec 2 A +  Cosec 4 A  + 1  - 2 Cosec 2 A
