Answer: x=-6
Step-by-step explanation:
Undefined slopes are vertical lines, so there's no y variable in the equation. so you look at the point (-6, -8) and take out the y, which is negative eight. So your answer is negative six.
The equation of the line that passes through the point (-6, -8) and has an undefined slope will be y + 8 = m (x + 6).
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Then the equation of the line that passes through the point (-6, -8) and has an undefined slope will be
y + 8 = m (x + 6)
The equation of the line that passes through the point (-6, -8) and has an undefined slope will be y + 8 = m (x + 6).

2-31 The following grade-point averages apply to a random sample of graduating seniors. 3.812.732.513.093.28 3.512.861.203.133.24 Calculate: (a) sample range
Answer:
The sample range is 2.61.
Step-by-step explanation:
We are given the following grade-point averages which apply to a random sample of graduating seniors below;
3.81, 2.73, 2.51, 3.09, 3.28, 3.51, 2.86, 1.20, 3.13, and 3.24.
As we know that the range of the data is calculated bu using the following formula;
Range = Highest value in the data - Lowest value in the data
Here, Highest value = 3.81
Lowest value = 1.20
So, the sample data range = 3.81 - 1.20
= 2.61.

A researcher measures the correlation between the frequency of self-esteem (high,low)and health status (lean/healthy,overweight/obese).Based on the frequencies for each nominal category given below,what is the value of the phi correlation coefficient?img Health status Lean/Healthy Overweight/ ObeseSelf Esteem Low 18 32 High 32 18
A) 0.08
B) 0.28
C) 0.52
D) 0.56
Answer: B) 0.28
Step-by-step explanation:
Given that:
Lean/Healthy Overweight/ ObeseSelf Esteem Low 18 32 High 32 18
Overweight/Obese Lean/Healthy Total
Low 32 18 50
High 18 32 50
Total 50 50 100
the phi correlation coefficient is defined by Ф = √x²/n
where n = 100 ( total number of response )
x² = [(32×32 - 18×18)² × 100] / [50 × 50 × 50 × 50]
Ф = √ [(700)² x 100) / (50)⁴ × 100
Ф = 700 / 50²
Ф = 0.28

What is the solution to the division problem? Enter numbers in the boxes to complete the problem.
Answer:52
Step-by-step explanation:
How many times can 8 go into 4. 0 so how many times can 8 go into 41 without going over 41.
8 x 5 = 40
41 - 40 = 1
bring down the next number which is 6
16 how many times can 8 go into 16, 2.
8 x 2 = 16
16 - 16 = 0
Start with the first number inside the division bracket (4). Because 8 can't go into 4, include the second number in the division bracket (1). Because 8 can go into 41 with a whole number, put a 5 above the bracket and subtract the value of 5*8 from 41. You should get 1. Then, bring down the 6 to form 16. Because 8 can evenly go into 16 twice, put a 2 next to the 5 above the bracket. Multiply 2*8 and subtract the value from 16.

the population of butterflies in a particular place is 50. if population increases by 20% in every 6 months . find out the population of butterflies after 1 year
Answer:
butterflies (b)=50
butterflies in 6 months =20/100×50=10+b =60
butterflies in 12 months =2(6months)
butterflies in 12 months= 120
The population of butterflies after 1 year is 72 butterflies
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the present population of butterflies be A = 50 butterflies
The percentage increase after 6 months = 20 %
The population of butterflies after 6 months = present population of butterflies + percentage increase after 6 months
The population of butterflies after 6 months = 50 + ( 20/100 ) x 50
= 50 + ( 0.2 x 50 )
= 50 + 10
= 60 butterflies
The population after 6 more months = population of butterflies after 6 months + percentage increase after 6 months
The population after 6 more months = 60 + ( 20/100 ) x 60
= 60 + 0.2 x 60
= 60 + 12
= 72 butterflies
Hence , The population of butterflies after 1 year is 72 butterflies

One exterior angle of a regular pentagon has a measure of (2x)”. What is the value of x?
O x = 18
O x = 20
O x= 30
O x= 36
Answer:
x = 36°
Step-by-step explanation:
The sum of the exterior angles of a pentagon is always 360°. Since the pentagon is regular, meaning that all of its sides and interior angles are congruent, we know that all of the exterior angles are also congruent. Since a pentagon has 5 sides, we know that there are 5 congruent exterior angles, therefore:
5 * 2x = 360
10x = 360
x = 36°
The value of x in the Pentagon is 36.
Option D is the correct answer.
What is a Pentagon?A pentagon is a polygon that has five sides and five angles.
The sides and angles of a pentagon are not all equal unless it is a regular pentagon.
A regular pentagon has five equal sides and five equal angles.
We have,
The sum of the exterior angles of any polygon is 360 degrees.
Since a regular pentagon has 5 sides, the sum of its exterior angles is 360 degrees.
Each exterior angle of a regular pentagon has a measure of:
= 360 degrees / 5
= 72 degrees
We are given that one exterior angle of the pentagon has a measure of (2x) degrees.
2x = 72
Solving for x.
x = 36
Therefore,
The value of x is 36, and the measure of the given exterior angle.
= (2x)
= 72 degrees.
Thus,
The value of x is 36.

Which is the correct pair?
Answer: D
Step-by-step explanation:
Since we are given that the x value is -1, we can eliminate A and C because the -1 is in the y coordinate.
To find the proper y value, we plug x into the equation.
y=-2x+5 [plug in x=-1]
y=-2(-1)+5 [multiply -2 and -1]
y=2+5 [add 2 and 5]
y=7
Now that we have the y value, we know the coordinate (-1,7) which makes D the correct answer.

what is 8/9 minus 1/3
Answer: Hi!
Your answer is 5/9.
Step-by-step explanation:
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 8 by 3, and get 24.
Then we multiply 1 by 9, and get 9.
Next we give both terms new denominators -- 9 × 3 = 27.
So now our fractions look like this:
24/27 - 9/27
Since our denominators match, we can subtract the numerators.
24 − 9 = 15
So the answer is:
15/27
(After you simplify it, it will be 5/9.)
Hope this helps!
The value of the expression "8/9 minus 1/3" is 5/9.
To subtract fractions, we need a common denominator. In this case, the least common multiple (LCM) of 9 and 3 is 9.
We can convert both fractions to have a denominator of 9:
(8/9) - (1/3)
Multiplying the numerator and denominator of the first fraction by 3, we get:
(8/9) - (1/3)
This gives us:
8/9 - 1/3
Since both fractions now have a common denominator of 27, we can subtract the numerators:
(8 - 3x 1) / 9
= (8-3)/9
= 5/9.
Therefore, 8/9 minus 1/3 is equal to 5/9.

l = 10+2w
48 = (10 + 2w)w
48 = 10w + 2w² | : 2
24 = 5w + w²
w² + 5w - 24 = 0
w² + 8w - 3w - 24 = 0
w(w + 8) - 3(w + 8) = 0
(w - 3)(w + 8) = 0
w - 3 = 0 => w = 3 feet
w + 8 = 0 => w = - 8 ∉ N
