What is the slope of the line that passes through the points (-9, -7) and (-11, -6) Write your answer in simplest form.

= 65% x 140 = 91

65..............100

n.................140

n = 140 x 65 : 100 = 91

Answer:

Hello! :) I hope I’m correct!!

Step-by-step explanation:

I think (C) 30 is not a perfect square.

(A) 1 = perfect square

(B) 25 = perfect square

(C) 30 = NOT a perfect square

(D) 36= perfect square

{Note: The square root of 30 is not an integer, so therefore 30 is not a square number}

Since the question is asking to find a number that is NOT a perfect square...

The answer would be (C) 30

Hope this helps! If you have any questions about this, feel free to ask! Have a wonderful day! ^-^

Answer:

a)  Shelton’s total pay before deduction: 10.25x

b)  To meet savings goal he'll have to work 827.415869 hours.

Step-by-step explanation:

Take-home pay:

  10.25x − 0.21(10.25x)

  10.25x − 2.1525x

  8.0975x

Save 25% for new laptop:

  .25(8.0975x) = 1675

     2.024375x = 1675

     x = 827.415869 hours

So, we have the following equation...

[tex]5^2+20=(?)[/tex]

Remember, 5² also means 5x5.

Therefore, [tex]5x5=25\\25+20=45[/tex]

This means your final answer is 45.

Answer:

oranges $3.50 per Kg, bananas $3 per Kg

Step-by-step explanation:

let b represent cost of bananas and o represent cost of oranges , then

2b + 3o = 16.5 → (1)

o = b + 0.5 → (2)

substitute o = b + 0.5 into (1)

2b + 3(b + 0.5) = 16.5 ← distribute parenthesis on left side and simplify

2b + 3b + 1.5 = 16.5

5b + 1.5 = 16.5 ( subtract 1.5 from both sides )

5b = 15 ( divide both sides by 5 )

b = 3

substitute b = 3 into (2)

o = 3 + 0.5 = 3.5

cost of oranges = $3.50 and cost of bananas = $3

The equation the function after the transformation is  g(x) = -4x² - 16

Transformations are changes done in the shapes on a coordinate plane by rotation, reflection or translation.

here, we have,

to determine the transformation of the function:

The equation of the function is given as

f(x) = x²+2

The sequence of transformations is given as follows:

Translate up by 2 units

Reflection across the x-axis

Vertically stretched by a factor of 4

When the above transformations are combined, we have:

Translate up by 2 units: g(x) = f(x) + 2

Reflection across the x-axis: g(x) = -(f(x) + 2)

Vertically stretched by a factor of 4: g(x) = -4(f(x) + 2)

So, we have

g(x) = -4(x²+2 + 2)

Expand

g(x) = -4x² - 16

Hence, the function g(x) is g(x) = -4x² - 16

Answer:

4x + 8y =12                        [inconsistent]

x + 2y = -3

x = 6                                   [inconsistent]

x = -2

2y = 5x + 6                          [inconsistent]

-10x + 4y = 8

x - 3y=2

4x - 12y = 8                          [dependent]

x+ 4y = 12                              [independent]

2x - 8y = 4

4x + 8y = -6                        [dependent]

6x + 12y = -9

4y - 2x = 6                            [inconsistent]

8y = 4x -12

y - x = 0                                [independent]

y = -x

2y - x = 4

1/2x - y = 2                            [inconsistent]

Answer:

5 terms

to the fourth degree

leading coeff of 1

3 turning points

end behavior (when x -> inf, y -> inf. When x -> - inf, y -> -inf)

x intercepts are (0,-4) (0,-2) (0,1) (0,3)

Relative min: (-3.193, -25) (2.193, 25)

Relative max: (-0.5, 27.563)

Step-by-step explanation:

The terms can be counted, seperated by the + and - in the equation given.

The highest exponent is your degree.

The number before the highest term is your leading coeff, if there is no number it is 1.

The turning points are where the graph goes from falling to increasing or vice versa.

End behaviour you have to look at what why does when x goes to -inf and inf.

X int are the points at which the graph crosses the x-axis.

The relative min and max are findable if you plug in the graph on desmos or a graphing calculator.

Answer: Mount Everest (8,848 m 29,029 ft) was first climbed, when the summit was reached by Edmund Percival Hillary

[tex]\\ \rm\rightarrowtail 2-sin^2x=2cos^2\left(\dfrac{x}{2}\right)[/tex]

[tex]\\ \rm\rightarrowtail 1+1-sin^2x=2cos^2\left(\dfrac{x}{2}\right)[/tex]

[tex]\\ \rm\rightarrowtail 1+cos^2x=2cos^2\left(\dfrac{x}{2}\right)[/tex]

[tex]\\ \rm\rightarrowtail cosx=1[/tex]

[tex]\\ \rm\rightarrowtail x=n\pi[/tex]

As x lies in between 0 and 2π

Answer:

[tex]x=0,\dfrac{\pi}{2}, \dfrac{3\pi}{2},2\pi[/tex]

Step-by-step explanation:

Given equation:

[tex]2-\sin^2x=2 \cos^2(\frac{x}{2})[/tex]

Subtract [tex]2 \cos^2(\frac{x}{2})[/tex] from both sides:

[tex]\implies 2-\sin^2x-2 \cos^2(\frac{x}{2})=0[/tex]

Pythagorean identity

[tex]\sin^2x+\cos^2x =1[/tex]  

[tex]\implies \sin^2x =1-\cos^2x[/tex]

Substituting into the equation:

[tex]\implies 2-(1-\cos^2x)-2 \cos^2(\frac{x}{2})=0[/tex]

[tex]\implies 1+\cos^2x-2 \cos^2(\frac{x}{2})=0[/tex]

Cosine double angle identity:

[tex]\cos(2x)=2 \cos^2x-1[/tex]

[tex]\implies 2 \cos^2x=\cos(2x)+1[/tex]

Substituting [tex]\frac{x}{2}[/tex] for [tex]x[/tex]:

[tex]\implies 2 \cos^2(\frac{x}{2})=\cos(2\cdot\frac{x}{2})+1[/tex]

[tex]\implies 2 \cos^2(\frac{x}{2})=\cos x+1[/tex]

Substituting into the equation:

[tex]\implies 1+\cos^2x- (\cos x +1)=0[/tex]

[tex]\implies \cos^2x- \cos x =0[/tex]

Factoring:

[tex]\implies \cos x(\cos x- 1)=0[/tex]

Therefore,

[tex]\cos x=0[/tex]  

[tex]\implies x=\dfrac{\pi}{2}, \dfrac{3\pi}{2}[/tex]

and  [tex]\cos x-1=0[/tex]

[tex]\implies \cos x=1[/tex]

[tex]\implies x=0, 2\pi[/tex]

Answer:

[tex]P(Red) = 0.125[/tex]

Step-by-step explanation:

Given

[tex]Red: 150[/tex]

[tex]White: 450[/tex]

[tex]Green: 225[/tex]

[tex]Blue: 375[/tex]

Required

Determine the probability of getting a red chair, next.

First, we nee the total number of chairs

[tex]Total = 150 + 450 + 225 + 375[/tex]

[tex]Total = 1200[/tex]

Probability of getting red is then calculated as thus;

[tex]P(Red) = Red/Total[/tex]

[tex]P(Red) = 150/1200[/tex]

[tex]P(Red) = 0.125[/tex]
