Answer:

Yes, it's undefined.

The slope is undefined.

Step-by-step explanation:

Slope formula:

[tex]\displaystyle \frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\displaystyle \frac{5-(-3)}{6-6}=\frac{8}{0}=0[/tex]

Therefore, the slope is undefined.

Hope this helps!

Answer:

undefined

Step-by-step explanation:

To find the slope of a line, we use the equation

m = (y2-y1)/(x2-x1)

    = (5--3)/(6-6)

   = (5+3)/(6-6)

  =8/0

 Anything divided by 0 is undefined, so the slope is undefined

Answer:

k = - 9

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use any ordered pair from the given table of values

Using x = 1, y = - 9, then

k = [tex]\frac{y}{x}[/tex] = [tex]\frac{-9}{1}[/tex] = - 9

Answer:

-9.

Step-by-step explanation:

y varies directly as x so y = kx where k is the constant of variation.

Inserting the values of x and y.

0 = k*0

-9 = k*1 so k = -9

-18 = 2*k so k = -9

-27 = 3 *k so k = -9.

Answer:

The measure of the smaller angle is 62°

Step-by-step explanation:

we know that

If two angles form a linear pair, then their sum is equal to 180 degrees (supplementary angles)

so

(2x-30)°+(x-12)°=180°

Solve for x

3x=180°+42°

3x=222°

x=74°

The measure of the angles are

(2x-30)°=2(74)-30=118°

(x-12)°=74-12=62° -----> smaller angle

Answer:

The coordinates of point B are (-7 , -2)

Step-by-step explanation:

* Lets explain how to solve the problem

- The mid-point (x , y) of the line whose endpoints are (x1 , y1) and

 (x2 , y2) is [tex]x=\frac{x_{1}+x_{2}}{2},y=\frac{y_{1}+y_{2}}{2}[/tex]

∵ M is the midpoint of AB

∵ The coordinates of point A are (-3 , 6)

∵ The coordinates of point M are (-5 , 2)

- Let the coordinates of point A are (x1 , y1) , The coordinates of

 point B are (x2 , y2) and The coordinates of point M are (x , y)

∴ x = -5 , x1 = -3 and y = 2 , y1 = 6

- Lets use the rule of the mid point to find x2 , y2

∵ [tex]-5=\frac{-3+x_{2}}{2}[/tex] ⇒ multiply both sides by 2

∴ [tex]-10=-3+x_{2}[/tex] ⇒ add 3 to both sides

∴ -7 = x2

∵ [tex]2=\frac{6+y_{2}}{2}[/tex] ⇒ multiply both sides by 2

∴ [tex]4=6+y_{2}[/tex] ⇒ subtract 6 from both sides

∴ -2 = y2

∵ The coordinates of point B are (x2 , y2)

∴ The coordinates of point B are (-7 , -2)

Answer:

Ratio of the number of votes that were not for mayor Jackson to the total number of votes is 3:7

Step-by-step explanation:

Votes of Mayor Jackson = 32,000

Total Votes = 56,000

Votes not for Mayor Jackson = 56000 - 32000

Votes not for Mayor Jackson = 24000

ratio of the number of votes that were not for mayor Jackson to the total number of votes = Votes not for Mayor Jackson:Total Votes

= 24,000:56,000

=3:7

So, ratio of the number of votes that were not for mayor Jackson to the total number of votes is 3:7

Answer:

3 : 7

Step-by-step explanation:

It is given that,

In an election 32,000 people voted for Mayor Jackson

A total of 56,000 people voted in the election.

To find the ratio

Total number of people voted = 56000

Number of people voted for Mayor Jackson = 32000

Number of  votes that were not for mayor Jackson = 56000 - 32000 = 24000

The question is on interquartile range which is the median of the upper half of the data minus the median of the lower half of data

First arrange the data in an increasing order;

8,15,9,18,9,17,22,10,11,9,13

8,9,9,9,10,11,13,15,17,18,22

Find the median, which is the center value in the data set

8,9,9,9,10,11,13,15,17,18,22⇒the median is 11

Place brackets around the numbers above and below the median

Final answer:

The discriminant of a quadratic equation informs us about the nature of its roots. By calculating the discriminant for each given equation, we categorize them accordingly: equations with discriminant greater than zero have two distinct real roots, equal to zero have one repeated real root, and less than zero have two complex roots.

Explanation:

The discriminant of a quadratic equation ax² + bx + c = 0 is given by the expression b² - 4ac. The value of the discriminant determines the nature of the roots of the equation. To find the type of roots for each given equation:

x² − 4x + 2: The discriminant is (-4)² - 4(1)(2) = 16 - 8 = 8, which is greater than zero, so this equation has two distinct real roots.

5x² − 2x + 3: The discriminant is (-2)² - 4(5)(3) = 4 - 60 = -56, which is less than zero, indicating two complex roots.

2x² + x − 6: The discriminant is (1)² - 4(2)(-6) = 1 + 48 = 49, also greater than zero, leading to two distinct real roots.

13x² − 4 = 0 has a discriminant equivalent to that for x² − 4/13 = 0, which is 0² - 4(1)(-4/13) = 16/13, which is greater than zero, so this equation will have two distinct real roots.

x² − 6x + 9: The discriminant is (-6)² - 4(1)(9) = 36 - 36 = 0, indicating one repeated root.

x² − 8x + 16: The discriminant is (-8)² - 4(1)(16) = 64 - 64 = 0, which means this equation has one repeated root.

4x² + 11 = 0 has a discriminant equivalent to that for x² + 11/4 = 0, which is 0² - 4(1)(11/4) = -11, less than zero, thus resulting in two complex roots.

Through the method of using the discriminant, we can determine the types of roots each quadratic equation will have.

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

From the graph we have two points (-5, -1) and (-2, -3).

Look at the picture.

Calculate the slope:

[tex]m=\dfrac{-3-(-1)}{-2-(-5)}=\dfrac{-2}{3}=-\dfrac{2}{3}[/tex]

Put it to the equation in slope-intercept form:

[tex]y=-\dfrac{2}{3}x+b[/tex]

We can't read the y-intercept from the graph. Therefore put the coordinates of the point (-5, -1) to the equation and calculate b:

[tex]-1=-\dfrac{2}{3}(-5)+b[/tex]

[tex]-1=\dfrac{10}{3}+b[/tex]         subtract 10/3 from both sides

[tex]-\dfrac{3}{3}-\dfrac{10}{3}=b\to b=-\dfrac{13}{3}[/tex]

Finally:

[tex]y=-\dfrac{2}{3}x-\dfrac{13}{3}[/tex]

Final answer:

To solve the inequality Ax - 8 ≤ 12 for x in terms of a, add 8 to both sides to get Ax ≤ 20, and then divide by A (assuming A > 0) to find x ≤ 20/A.

Explanation:

To solve the inequality for x in terms of a, we start with the given inequality:

Ax - 8 ≤ 12.

First, we add 8 to both sides to isolate the term with x on one side:

Ax ≤ 20

Next, assuming A is not zero, we divide both sides by A to solve for x:

x ≤ 20 / A

This is the solution to the inequality, with the understanding that it only applies if A is positive, because if A were negative, we would need to reverse the inequality sign when dividing by A.
