Step-by-step explanation:

m =  y2 - y1/x2 - x1

= 6-6/-9-(-9)

= 6-6/-9+9

m = 0/0

Answer:

slope is indeterminate

Step-by-step explanation:

Given (- 9, 6) and (- 9, 6) ← that is a single point

No line is formed by a point , thus the slope is indeterminate

Answer:

15) The equation to find the sum of interior angles is

(n - 2).180

which means that a polygons interior angles will always be a multiple of 180 because they are multiplied by it.

Answer:

Step-by-step explanation:

1- Remove any grouping symbol such as brackets and parentheses by multiplying factors.

2- the exponent rule to remove grouping if the terms are containing exponents.

3- Combine the like terms by addition or subtraction.

4- Combine the constants.

Answer:

t = total money spent

t = $2.99g + $3.25c

for b just plug in g and c

$2.99(7.9) + $3.25(4)

if you put it into a calculator you get that he spent a total amount of $36.62 for the 7.9 gallons of gas and the 4 cans of oil. (:

Answer:

40°

Step-by-step explanation:

Angles on a straight line add up to 180

180 - 110 = 70

As it's an isosceles triangle the opposite angles are the same

70 + 70 = 140

180 -140 = 40

Answer:

Step-by-step explanation:

180-110=70

x+70+70=180

x=180-140=40°

Step-by-step explanation:

Answer:

y = 5/6x + 4

Step-by-step explanation:

y = mx + b

b = 4 because when x = 0, y = 4

m  = (y2 -y1) / (x2 - x1)

where two points on the equation are (x1, y1) & (x2, y2)

Let's pick points (6,9) & (-6,-1)

m = (-1 - 9) / (-6 - 6)

m = -10 / -12 = 5/6

Step-by-step explanation:

Hence, the five positive integers are 2, 2, 4, 4, 13.

Mean- The arithmetic mean of a given data is the sum of all observations divided by the number of observations.

Median-The value of the middlemost observation, obtained after arranging the data in ascending or descending order, is called the median of the data.

Mode-The value which appears most often in the given data i.e. the observation with the highest frequency is called a mode of data.

According to the question , it can be concluded that the total no. of observations are 5.

So , Let n=5

Let  the integers be a, b, c, d and e

The question says that mode(s) are 2  and 4.

This indicates that 2 and 4 both have occurred more than once , and both have same frequency since both are modes.

Since we have only 5 integers , and 2 and 4 both are modes , so both these numbers have possibility to occur only twice.

Hence , it becomes , a=2 , b=2 , c=4 , and d=4

Hence we can say that out of five required integers ,four of them are 2 and 4.

Further , we are given that mean is 5.

therefore , using formula:

Mean = Sum of Observations / Number of observations(n)

Mean=  (a+b+c+d+e) / 5

5 = (2+2+4+4+e) / 5

5 = (12+e)/5

Multiplying both sides by 5 , we get :

25 = 12+e

e=25-12

Hence , e = 13

So,  the five positive integers are 2, 2, 4, 4, 13.

Step-by-step explanation:

We can write the following ratio

1:3 (for every student who gets an A 3 gets a b)

We then can write a new ratio

4:x

We can solve this ratio by multiplying the original ratio by 4

4:12

This means that 12 people earned an B

Answer:

x = 8

Step-by-step explanation:

sin (30) = 4/x => solve for x.

Answer:

[tex]x=8[/tex]

Step-by-step explanation:

Use the sine ratio because we have the hypotenuse and side opposite the given angle to work with:

[tex]sineX=\frac{opposite}{hypotenuse}[/tex]

Insert the values:

[tex]sin30=\frac{4}{x}[/tex]

Multiply both sides by x:

[tex]x(sin30)=x(\frac{4}{x} )\\\\x*sin30=4[/tex]

Divide both sides by sin30°:

[tex]\frac{x*sin30}{sin30} =\frac{4}{sin30}\\\\x= \frac{4}{sin30}[/tex]

Insert the value of x into a calculator:

[tex]x=8[/tex]

OR:

The little red square means that angle is 90º, and the other given angle is 30°. Since every triangle has a measure of 180°, the other missing angle is 60°. The given triangle is a 30°-60°-90° triangle with the following rules:

[tex]long.leg=short.leg*\sqrt{3}\\\\hypotenuse=short.leg*2[/tex]

The hypotenuse is represented by the variable x. We are given the value of the short leg, which is 4. Solve for the hypotenuse:

[tex]h=4*2\\\\h=8[/tex]

Therefore, the value of x is 8.
