What values of X make the two expressions below equal?

Answer:

You would have to break the polynomial down into smaller binomials or monomials. Take x^2-6x-9 for instance. It would break down into (x+3)(x-3) through the a^2+2ab+b^2 formula. After that set the two nomials equal to zero and solve for x. After that, you would plug back in x to see whatever x works. You may more than two nomials after breaking it apart so keep that in mind.

your statement is x=2y

3(2x+4),  2(3x+6) and 6(x + 2) are the expressions are equivalent to 6X +12

An expression is combination of variables, numbers and operators.

The given expression is 6X +12

We have to find the equivalent expressions of 6x+12

Let us take 6 as a common factor we get

6(x+2)

so 6(x+2)  is equivalent expression of 6X +12

Now let us take 3 as common factor

3(2x+4)

so 3(2x+4)  is equivalent expression of 6X +12

Now let us take 2 as common factor

2(3x+6)

so 2(3x+6)  is equivalent expression of 6X +12

Hence,  3(2x+4),  2(3x+6) and 6(x + 2) are the expressions are equivalent to 6X +12

Answer:

The restaurant is not at half way

Step-by-step explanation:

Given

[tex]Total\ Distance = 72[/tex]

[tex]Diego = 16x - 3[/tex]

[tex]Anya = 5x + 2[/tex]

Required

Accept or reject Diego's claim

To do that, we need to determine the value of x by:

Diego + Anya =Total Distance

Substitute values for each parameter

[tex]16x - 3 + 5x + 2 = 72[/tex]

Collect Like Terms

[tex]16x + 5x = 72 + 3 - 2[/tex]

[tex]21x = 73[/tex]

Divide both sides by 21

[tex]x = \frac{73}{21}[/tex]

Substitute the value of x in Diego and Anya's distance

[tex]Diego = 16x - 3[/tex]

[tex]Diego = 16 * \frac{73}{21} - 3[/tex]

[tex]Diego = \frac{1168}{21} - 3[/tex]

[tex]Diego = \frac{1168 - 63}{21}[/tex]

[tex]Diego = \frac{1105}{21}[/tex]

[tex]Diego = 52\frac{13}{21}[/tex]

[tex]Anya = 5x + 2[/tex]

[tex]Anya = 5 * \frac{73}{21} + 2[/tex]

[tex]Anya = \frac{365}{21} + 2[/tex]

[tex]Anya = \frac{365 + 42}{21}[/tex]

[tex]Anya = \frac{407}{21}[/tex]

[tex]Anya = 19\frac{8}{21}[/tex]

Since, both distances are not equal,

Then Diego's claim is false and incorrect

Step-by-step explanation:

6.79 x 10 = 67.9

The unknown number z would be 6.79

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

WE have been given that 67.9 is ten times as much as unknown number;

Let the unknown number be z;

Z x 10 = 67.9

Now divide by 10 on both sides, we get;

Z = 67.9/10

Z = 6.79

Therefore,

6.79 x 10 = 67.9

Hence, the unknown number z would be 6.79

Answer:

$56.82

Step-by-step explanation:

The sum of all the stuff she bought is 10+20+23, so 53.

Now you need to find the tax, so you multiply 53 x 7.2%, and to change a % to a number you move the decimal place two to the left, so you get .072

$53 x .072 = $3.816 sales tax

$53 for the stuff plus $3.816 tax = $56.816

and since money is only two decimal places and the 6 is higher than 5, you have to round up to the nearest penny, so $56.82!

Given :

A line 2x + 1 =0 .

To Find :

The slope of the given line .

Solution :

We know , slope of line is given by the tangent of the angle between the x-axis and the line .

Now, for line 2x + 1 =0 i.e [tex]x=\dfrac{-1}{2}[/tex] .

The line is perpendicular to x-axis and cuts the x-axis at [tex]\dfrac{-1}{2}[/tex] .

Therefore , the angle between the line and x-axis is [tex]90^o[/tex] .

So , slope [tex]m=\tan\ 90^o[/tex] i.e undefined .

Therefore , the slope of given line is not defined .

Hence , this is the required solution .

Step-by-step explanation:

M₄ means the area using 4 rectangles with heights equal to the function evaluated at the midpoints.

The width of each rectangle is (4−0)/4 = 1.

The area of each rectangle is:

M₁ = (1) (1.12) = 1.12

M₂ = (1) (1.80) = 1.80

M₃ = (1) (2.69) = 2.69

M₄ = (1) (3.64) = 3.64

The total area is therefore:

M = 1.12 + 1.80 + 2.69 + 3.64

M = 9.25

Answer : The equation for 'h' is [tex]h=\frac{2A}{b}[/tex]

Step-by-step explanation :

The given equation is:

[tex]A=\frac{1}{2}bh[/tex]

Now we have to determine the equation for 'h'.

[tex]A=\frac{1}{2}bh[/tex]

Multiplying the equation by 2.

[tex]2\times A=2\times \frac{1}{2}\times bh[/tex]

on simplifying, we get:

[tex]2\times A=bh[/tex]

Dividing the equation by 'b'.

[tex]\frac{2\times A}{b}=\frac{bh}{b}[/tex]

[tex]\frac{2\times A}{b}=h[/tex]

or,

[tex]h=\frac{2A}{b}[/tex]

Therefore, the equation for 'h' is [tex]h=\frac{2A}{b}[/tex]

The question is not too clear. check the attachment for better view of the question.

From the options The set A = {2, 3, 4} will be compared to other options to determine which of the remaining set is equivalent to the set A.

x e R means the values in the set are real numbers and real numbers can either be rational or irrational. R= Hence the real numbers between  1 and 5 are not restricted to only positive integer values but also decimal numbers. and since set A does nit contain ant rational number, hence both set B and C are not equivalent to set A.

Also, set B is not equivalent to set C even though the values in both sets are integers. They are not equal because 1 is included in set B but not in set C.

Set D and E are equivalent because they both contains integers between 1 and 5. Integers are positive whole numbers between 1 and 5 since the both sets doesn't contain any negative value. Hence the set A = set D = set E

Answer:

The equation of the tangent line

[tex]y - \frac{\pi }{4} = (\frac{-\pi }{2} +1)( x - \frac{\pi }{4} )[/tex]

Step-by-step explanation:

Step(i):-

Given function y = x cot (x) ....(i)

Differentiating equation (i) with respective to 'x' , we get

[tex]\frac{dy}{dx} = x (-Co sec^{2} (x)) +cot(x) (1)[/tex]

Step(ii):-

The slope of the tangent line

[tex]\frac{d y}{d x} = -x Co-sec^{2} (x) +cot x[/tex]

[tex](\frac{d y}{d x} )x_{=\frac{\pi }{4} } = -\frac{\pi }{4} Co-sec^{2} (\frac{\pi }{4} ) +cot \frac{\pi }{4}[/tex]

We will use trigonometry formulas

[tex]Cosec(\frac{\pi }{4} ) = \sqrt{2}[/tex]

[tex]sec(\frac{\pi }{4} ) = \sqrt{2}[/tex]

[tex]Cot(\frac{\pi }{4} ) = 1[/tex]

Now the slope of the tangent

[tex]\frac{dy}{dx} =-\frac{\pi }{4} (\sqrt{2})^{2} )+1[/tex]

[tex]\frac{dy}{dx} =-\frac{\pi }{2} +1[/tex]

Step(iii):-

Given

Substitute [tex]x=\frac{\pi }{4}[/tex] in y = x cot (x)

               [tex]y = \frac{\pi }{4} cot (\frac{\pi }{4} )[/tex]

              [tex]y = \frac{\pi }{4}[/tex]

The point of the tangent line  [tex](x ,y ) = (\frac{\pi }{4} , \frac{\pi }{4} )[/tex]

The equation of the tangent line

[tex]y - y_{1} = m ( x - x_{1} )[/tex]

[tex]y - \frac{\pi }{4} = (\frac{-\pi }{2} +1)( x - \frac{\pi }{4} )[/tex]
