Answer:

y = - 1/2x - 4.5

Step-by-step explanation:

Step 1:

x + 2y = - 9         Equation

Step 2:

2y = - x - 9       Subtract x on both sides

Answer:

y = - 1/2x - 4.5             Divide 2 on both sides

Hope This Helps :)

Answer:

This is not a function. This is because if there are any repeating x values (the first values of each set) it is not a function. It is okay for there to be repeating y values (the second values of each set) but not x values.

Step-by-step explanation:

I am guessing the question is if this is a function.

Answer:

c. 0.1391 < Ï < 0.2311

Step-by-step explanation:

The formula for Confidence Interval is given as:

Mean ± z × Standard deviation/√n

Z score for 98% confidence interval = 2.326

Mean = Significance level = 100% - 98%

= 2% = 0.02

Standard deviation = S=0.0165

n= 37

Hence,

Confidence Interval =

0.02 ± 2.326 × 0.0165/√37

0.02 ± 0.0063094687

Confidence Interval

0.02 - 0.0063094687

= 0.1391

0.02 ± 0.0063094687

= 0.2311

Hence, the Confidence Interval = (0.1391, 0.2311)

= c. 0.1391 < Ï < 0.2311

Answer:

Step-by-step explanation:

(x₁, y₁) = (19 , -4)   & (x₂ ,y₂) = (17, -20)

[tex]Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

        [tex]= \frac{-20-[-4]}{17-19}\\\\= \frac{-20+4}{17-19}\\\\= \frac{-16}{-2}\\\\= 8[/tex]

m = 8

Parallel lines have same slope.

Parallel slope = 8

Slope of perpendicular line = [tex]\frac{-1}{m}[/tex]

Perpendicular slope = [tex]\frac{-1}{8}[/tex]

(b) 84

(c) 20

Step-by-step explanation:

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

[tex]{n\choose k}=\frac{n!}{k!\cdot(n-k)!}[/tex]

(a)

Compute the number of ways to select 9 applicants from 100 as follows:

[tex]{100\choose 9}=\frac{100!}{9!\cdot(100-9)!}[/tex]

        [tex]=\frac{100!}{9!\times 91!}\\\\=\frac{100\times 99\times 98\times 97\times 96\times 95\times 94\times 93\times 92\times 91!}{9!\times 91!}\\\\=\frac{100\times 99\times 98\times 97\times 96\times 95\times 94\times 93\times 92}{9!}\\\\=1902231808400[/tex]

(b)

Compute the number of ways to select 6 people from 9 as follows:

[tex]{9\choose 6}=\frac{9!}{6!\cdot(9-6)!}[/tex]

        [tex]=\frac{9!}{6!\times 3!}\\\\=\frac{9\times 8\times 7\times 6!}{6!\times 3!}\\\\=\frac{9\times 8\times 7}{3!}\\\\=84[/tex]

(c)

Compute the number of ways to select top 3 candidates from 6 as follows:

[tex]{6\choose 3}=\frac{6!}{3!\cdot(6-3)!}[/tex]

        [tex]=\frac{6!}{3!\times 3!}\\\\=\frac{6\times 5\times 4\times 3!}{3!\times 3!}\\\\=\frac{6\times 5\times 4}{3!}\\\\=20[/tex]

Answer:

B. -4, -3

Step-by-step explanation:

The equation x^(2) + 7x + 12 can be factored using the AC method resulting in

( x + 4 )( x + 3 ).  So x = -4, -3. You can use foil to check.

Answer:

It is the second circle  I believe

Step-by-step explanation:

As you can see on the x side is always just going up 1, and the y side is 2 numbers behind the x side in the beginning. But the y side catches up to the x side, which you can see once the x and y side both have positive 1's. The the y side goes up 2 more while the x side only goes up once.

Answer: -14, -17, and -20

Step-by-step explanation: Study the sequence.

Notice that each number is 3 less than the number before it.

In other words, -2 - 3 is -5, -5 - 3 is -8, and -8 - 3 is -11.

Now, if we continue with this same sequence,

-11 - 3 is -14, -14 - 3 is -17, and -17 - 3 is -20.

So the next three numbers are -14, -17, and -20.

Your scientific or graphing calculator can tell you the sum and display it in scientific notation.

Answer:

Does a square have rotation symmetry? Yes, a square can be rotated \begin{align*}90^\circ\end{align*} counterclockwise (or clockwise) about its center and the image will be indistinguishable from the original square.

Step-by-step explanation:

Answer:

90°

Step-by-step explanation:

If you rotate a square about its axis, in 90°, 180°, 270°, 360°, ... degrees, it looks to be the same.

Answer:

it is at 210 feet

Step-by-step explanation:

it rises 340 feet, then it descends 130 so we subtract 130 from 340 which gets us 210 feet.

Step-by-step explanation:

Property of an isosceles triangle,

Opposite angles of the equal sides in an isosceles triangle are equal in measure.

m∠D = m∠F

(2x + 8) = (3x + 4)

3x - 2x = 8 - 4

x = 4

m∠D = m∠F = (3×4 + 4)°

                    = 16°

m∠D = m∠F = 16°

Since, sum of interior angles of a triangle = 180°

m∠D + m∠E + m∠F = 180°

16° + m∠E + 16° = 180°

m∠E = 180° - 32°

m∠E = 148°

Answer:

perpendicular

Step-by-step explanation:

3y = x + 4 in slope intercept form y = 1/3x +4/3

3x + y = 1 in slope intercept form y = -3x +1

the slopes are negative reciprocals of each other so they are perpendicular

Answer:

These lines are perpendicular

Step-by-step explanation:

3y=x+4

 [tex]y = \frac{1}{3}x+\frac{4}{3}[/tex]

Slope (m1) = 1/3

3x+y=1

     y = -3x + 1

Slope (m2) = - 3

m1 * m2 = [tex]\frac{1}{3}* -3[/tex]

             = -1

So, these lines are perpendicular.

If product of two slopes is (-1), then they are perpendicular lines.

If both lines have same slope, then they are parallel.
