Answer:

When slope and one point are known follow instructions on this page:

http://www.1728.org/distance.htm

Calculate "b" from this equation:

b = y -mx where "m" is the slope

We'll use the point given (-2, -1) for "x" and "y"

b = -1 -(8/7) * -2

b = -1 + 16/7

b = 9/7

then we enter "b" and the slope into this equation

y = 8/7x +9/7

y = 1.142857 x + 1.2857142857

[tex]\boxed{\textsf{ The value of x is \textbf{ 8 + 6}$\sqrt{3 }$.}}[/tex]

Step-by-step explanation:

Here we are given a equation which we need today simplify and solve for x .The given equation to us is :-

[tex]\sf\implies \dfrac{1}{x {}^{2} - 3 } = \dfrac{ \sqrt{3} }{x + \sqrt{3} } - \dfrac{2}{ \sqrt{3} - x } [/tex]

Let's simplify the equation :-

[tex]\sf\implies \dfrac{1}{x {}^{2} - 3 } = \dfrac{ \sqrt{3} }{x + \sqrt{3} } - \dfrac{2}{ \sqrt{3} - x } \\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3}{x+\sqrt3}-\dfrac{2}{-(x-\sqrt3)}\\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3}{x+\sqrt3}+\dfrac{2}{x-\sqrt3}\\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3(x-\sqrt3)+2(x+\sqrt3)}{(x+\sqrt3)(x-\sqrt3)}\\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3x-3+2x+2\sqrt3}{x^2-3}\\\\\sf\implies 1=\sqrt3x-3+2x+2\sqrt3 \\\\\sf\implies \sqrt3x+2x = 4-2\sqrt3\\\\\sf\implies x(\sqrt3 +2)=4-2\sqrt3\\\\\sf\implies x =\dfrac{4-2\sqrt3}{\sqrt3+2}\\\\\sf\implies x =\dfrac{ (4-2\sqrt3)(\sqrt3-2)}{(\sqrt3+2)(\sqrt3-2)}\\\\\sf\implies x =\dfrac{-8-6\sqrt{3}}{3-4}\\\\\sf\implies \boxed{\pink{\sf x =8+6\sqrt3}}[/tex]

Answer:

3/18 or 1/6 in simplest form.

Step-by-step explanation:

We do (Y2-Y1)/(X2-X1).

(0--3)/(14--4)

When you subtract a negative, the sign turns positive.

(0+3)/14+4) =3/18

if you need to simply your answer it would be 1/6 because both the numerator and denominator are both divisible by 3.

Step-by-step explanation:

We have two shapes on a graph and the question is asking for the translation of rhombus QRST to rhombus Q'R'S'T.

Looking at the graph we can see that not only does the rhombus move backwards, but also downward, this indicates that our answers will be in a subtracting symbol.

So all we have to do is count the amount of spaces rhombus QRST went to get to rhombus Q'R'S'T

Answer:

[tex]Area = 81cm^2[/tex]

Step-by-step explanation:

Given

[tex]Length = 12[/tex]

[tex]Width = 6cm[/tex]

Required

Determine the area of a square with the same perimeter

First, calculate the perimeter (P) of the rectangle.

[tex]P=2*(Length + Width)[/tex]

[tex]P=2*(12 + 6)[/tex]

[tex]P=2*18[/tex]

[tex]P=36[/tex]

The perimeter of a square is:

[tex]P = 4L[/tex]

Where L is the side length.

Substitute 36 for P

[tex]36 = 4L[/tex]

Make L the subject

[tex]L =\frac{36}{4}[/tex]

[tex]L =9[/tex]

The area of the square is:

[tex]Area = L^2[/tex]

[tex]Area = 9^2[/tex]

[tex]Area = 81cm^2[/tex]

Hi there!

Let see...

100% subtract 30% would be 70%.

70% multiply by 0.01 is 0.7 or 0.70.

Multiply 0.70 by 6000.

It would be... 4200$.

Subtract 6000$ by 4200$.

The answer would be 1800$.

So this means that Lee would get 4200$ per month and the state income tax would be 1800$.

Lee's net salary is $4200

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here: Lee's gross salary is $6000 per month, but federal and state income tax totals about 30%. Therefore his gross salary is

6000×(1-30%)=$4200

Hence, his net salary is $4200

= 67.5[sin 12(x - 7.5) + 1]

= 67.5[sin(12x - 90) + 1]

Answer:

A) $287.60.

B) $323.55.

C) David would pay more for the laptop at the store.

Step-by-step explanation:

A) Given that the store's website is offering the laptop at a 60% discount off the regular price of $ 719, ignoring tax and shipping, the sale price is obtained through the following calculation:

100 - 60 = 40

719 x 0.40 = X

287.6 = X

Therefore, in this case the sale price would be $ 287.6.

B) Since the store is having a sale, offering a 50% discount off the regular price of the laptop, and David also has an in-store-only coupon for an additional 10% off the sale price, ignoring tax, the price of sale is obtained through the following calculation:

(719 x 0.5) x 0.9 = X

359.5 x 0.9 = X

323.55 = X

Thus, the sale price in the present case would be $ 323.55.

Answer:

x = .875 y = -49

Step-by-step explanation:

(8x - y = 42)

(y = -43 - 6) or (y = -49)

Since we have our y value, we can plug it into our top equation:

8x -(-49) = 42

8x + 49 = 42

      -42   -42

8x = 7

/8    /8

x = 0.875

To check the work:

8(0.875) - 49 = 42

7 - 49 = 42

Answer:

the answer is 59 (I got it on khan academy)

Step-by-step explanation:

59 degrees is the measures of the minor arc YZ if  diameter of a circle is XZ

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Given that diameter of a circle is XZ

We have to find the measure of arc YZ.

11w+5w+4=180

Add the like terms

16w+4=180

Subtract 4 from both sides

16w=176

Divide both sides by 16

w=176/16

w=11

Now plug in w value of yz

yz=5w+4

=5(11)+4

=55+4

=59 degrees

Hence, 59 degrees is the measures of the minor arc YZ.
