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

The distribution of the amount of money spent by first-time gamblers at a major casino in Las Vegas is approximately normal in shape with a mean of $600 and a standard deviation of $120. According to the standard deviation rule, almost 84% of gamblers spent more than what amount of money at this casino?
A. $360
B. $480
C. $600
D. $720
E. $840

Answers

Answer:

$720

Step-by-step explanation:

Given :

Mean, m = 600

Standard deviation, s = 120

Z = (x - m) / s

P(Z > x) = 84%

P(Z > x) = 0.84

Zscore corresponding to P(Z > x) = 0.84 will be -0.994

Hence,

-0.994 = (x - 600) / 120

120 * -0.994 = x - 600

119.28 = x - 600

119.28 + 600 = x

719.28 = x

Hence,

X = $720

Answers

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.

can someone please solve this?

Answers

Answer:

[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]

Solve the system by substitution.
8x – y = 42
-43 - 6 = y

Answers

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

Write an equation of the line through (-2, - 1) having slope
8/7?

Answers

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
