Answer:
D'(-6, -9)
Step-by-step explanation:
When a point is reflected over the x-axis, the x-coordinate remains the same. The reflected point is the same distance from the x-axis as the original point, but it's on the other side of the x-axis, so the y-coordinate changes sign.
In general, point (x, y) reflected over the x-axis becomes point (x, -y).
Here, point D(-6, 9) becomes point D'(-6, -9).
Type the integer that makes the following subtraction sentence true:
- -188 = -559
Submit
Answer: -787
188 is positive, negative and negative equals positive
559 is negative
the answer needs to be negative as 559 is negative so you add 559 and 188 and get 787 and add a negative sign so it's more "negative" than 188. (hard to explain in writing)
-787--188=-559
-787+188=-559
-559=-559
In circle M with m ∠ L M N = 106 and LM=4 units, find the length of arc LN. Round to the nearest hundredth.
The length of arc LN of the circle is 7.40 units rounded to the nearest hundredth.
How to calculate for the length of arc of a circleTo calculate for the length of an arc of a circle, we use 2πr × (θ/360), where r is the radius and θ is the angle formed from the arc.
Thus we evaluate for the length of the arc as follows;
for π = 3.14, r = 4 and θ = 106°
2 × 3.14 × 4 × (106/360)°
25.12 × 0.2944
7.3953
Therefore, the length of the arc 7.3953 and rounded up to 7.40 to the nearest hundredth.

Domain: (−∞,∞),{x|x∈R} and Range: (−∞,∞),{y|y∈R} for f(x)=0.5x
What is a function?A relation is a function if it has only One y-value for each x-value.
Given,
Helene is selling cupcakes for $0.50 each.
The function f(x)=0.5x gives the total amount of money Helene makes after selling x cup cakes.
We need to find the domain and range of the function
solve the equation f(x)=0.5x to determine the values of the independent variable x and obtain the domain.
To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).
Domain: (−∞,∞),{x|x∈R}
Range: (−∞,∞),{y|y∈R}
Hence, Domain: (−∞,∞),{x|x∈R} and Range: (−∞,∞),{y|y∈R} for f(x)=0.5x

Determine whether the following individual events are independent or dependent. Then find the probability of the combined event.
In a town where 1/4 of the days are sunny and 3/4 are cloudy, the next six days are all sunny.
The probability of the combined event that the next six days are all sunny is 1/4096
How to determine the probability all days being sunny?From the question, we have the following parameters that can be used in our computation:
Probability that it is sunny = 1/4
Probability that it is cloudy = 3/4
Number of days = 6
The probability for all six days, it is sunny is represented as
Probability = Probability that it is sunny^Number of days
Substitute the known values in the above equation, so, we have the following representation
Probability = (1/4)⁶
Express as decimal
Probability = (0.25)⁶
Evaluate the exponent
Probability = 1/4096

What exactly is a monthly payment?A monthly payment is a payment made every month to pay off loans or advances. It's similar to EMI.
Mary takes out a loan for $6,000 at a simple interest rate of 12% to be paid back in 36 monthly installments.
The total payback = P× r/100 × T + P
Here P = $6,000 , r = 12, and T = 3 years
The total payback = 6,000 × 12/100 × 3 + 6,000
The total payback = 6,000 × 0.12 × 3 + 6,000
The total payback = $8,160
The total payback of the borrowings will be $8,160 over a three-year period. The monthly payment for this will be,

Sample Response: The points on the number line do represent additive inverses. 3 and −3 are a zero pair, and when added they equal zero. The two numbers are the same distance from zero but in opposite directions. The following are reasons why 3 and −3 are additive inverses. Check all of the conditions you included in your response.
When two numbers added together result in 0, this is known as additive inverse. Using this notion, points on a number line are used to depict additive inverse.
Explain the term additive inverse?To get a result equal to 0, add the original number and the additive inverse by simply switching the sign of the integer. On the basis of negation of a original number, the characteristics of additive inverse are listed below. For instance, if x is the starting number, then -x is x's additive inverse.The dotted points with the numbers 3 and -3 are the places on the number line.
To determine whether the points show an additive inverse:
Points 1 and 2 add up to 0.
3 + (-3) = (3 - 3) = 0
When two numbers added together result in 0, this is known as additive inverse.
Using this notion, points on a number line are used to depict additive inverse.
Thus, the points therefore display additive inverse.

What is the mean absolute deviation of these numbers 76, 70, 66, 80, 72, 67, 78, 69
The mean absolute deviation of the given values would be = 4.3125
What is mean absolute deviation?The mean absolute deviation in statistics is defined as the average distance between each data point and the mean and this gives us an idea about the variability in the dataset.
To calculate the mean absolute deviation the following is carried out:
Calculate the mean of the given data:76, 70, 66, 80, 72, 67, 78, 69 = 578/ 8 = 72.25
Calculate the distance between each data point and the mean.76-72.25 = 3.75
70-72.25 = 2.25
66-72.25 = 6.25
80-72.25 = 7.75
72-72.25 = 0.25
67-72.25 = 5.25
78-72.25 = 5.75
69-72.25 = 3.25
The distance should be added together;3.75+2.25+6.25+7.75+0.25+5.25+5.75+3.25 = 34.5

Find the equation for the line that passes through the point (−1,4), and that is parallel to the line with the equation y−5=34(x−2)
In point-slope form, the equation of the parallel line to y − 5 = 3/4(x − 2) is: y - 4 = 3/4(x + 1).
What is the Equation of Parallel Lines?If two lines are parallel their equation, written in point-slope form y - b = m(x - a), will have the same value of m, which is the same slope.
The slope of the line with the equation y - 5 = 3/4(x - 2), is 3/4. This means that the line that passes through the point (−1, 4), and that is parallel to the line with the equation y − 5 = 3/4(x − 2), will have the same slope, m = 3/4.
To write the equation of the line that is parallel to y - 5 = 3/4(x - 2), in point-slope form, substitute m = 3/4 and (a, b) = (-1, 4) into y - b = m(x - a):
y - 4 = 3/4(x - (-1))
y - 4 = 3/4(x + 1)
The equation of the line that is parallel to y − 5 = 3/4(x − 2) is therefore expressed in point-slope form as: y - 4 = 3/4(x + 1).
