Answer:
If triangle HIJ is dilated about the center of the triangle to create triangle H'I'J', dilated line A'B' will be parallel to AB.Option (D) is correct.
Given:
The options are as follows,
(A). be perpendicular to AB.
(B). lie on the same line as AB.
(C). shift four units to the left.
(D). be parallel to AB.
Step-by-step explanation:
If we dilate triangle HIJ then the dilated triangle is bigger than the triangle HIJ.
The triangle HIJ is similar to triangle to each other.
So the line is parallel to side AB.

What is the value of X?
Answer:
x = 60
Step-by-step explanation:
<DGC = 90 degrees Given
<AGB = <DGC Vertically opposite angles.
<AGB = 90 degrees. <AGB takes on the properties of <DGB
30 + x + 90 = 180 The three angles make up a line.
120 + x = 180 Combine like terms..
x = 180 - 120 Subtract 120 from both sides
x = 60
please answer! giving branliest. provide me with answers, or answer sheet, thanks!
can you help meeee pls i dont understand this thanx

The sum of the residuals should always be 0 because the predicted values should be that close to the actual values.
True or false
Answer: True
Step-by-step explanation:
The sum of the residuals is always 0 so the plot will always be centered around the x-axis. An outlier is a value that is well separated from the rest of the data set. An outlier will have a large absolute residual value.
Noah bought stock in a company two years ago that was worth x dollars. During the first year that he owned the stock, it increased by 31%. During the second year the value of the stock increased by 15%. Write an expression in terms of x that represents the value of the stock after the two years have passed.
Answer:
1.5065x
Step-by-step explanation:
x + (0.31x) + 0.15(1.31x)
x is the initial amount, 0.31x is the 31% of the original amount, and we're adding that. The 15% earned the next year is on the new total of what he had after that first bump...x + 0.31x = 1.31x
Simplify:
x + (0.31x) + 0.15(1.31x)
= 1.31x + 0.1965x
=1.5065x

Combine like terms: 4-4z+5z-2+2z then solve
Answer:
3z+2
Step-by-step explanation:
Answer:
2 + 3z
Step-by-step explanation:
4 - 4z + 5z - 2 + 2z
4 - 2 = 2
-4z + 5z + 2z = 3z
= 2 + 3z
We don't know what 'z' is, so that is the most that I can simplify it.
4 - 4z + 5z - 2 + 2z
= (4) + (-4z) + (5z) + (-2) + (2z)

Answer:
shown below
Step-by-step explanation:
1. The pair of angles shown in your diagram are vertical angles. Vertical angles are each of the pairs of opposite angles made by two intersecting lines. The pairs of vertical angles have the exact same measurement. Therefore, 5x and 100 must have the same degree measurement, or 100 degrees. Thus, 5x must equal 100, so 5x = 100, and x would be 20 degrees.
2. The diagram shows a right angle (90 degrees) formed by 3x degrees and 39 degrees. 3x and 39 are complementary, which means they add up to 90, not 180 (that's supplementary). Thus, 3x + 39 = 90, 3x = 51, and x = 17 degrees.
3. The diagram shows a 180-degree angle formed by 6x degrees and 2x + 8 degrees. This means that 6x + (2x+8) equals 180. 6x + 2x + 8 = 180 and 8x + 8 = 180, 8x = 172, and x = 21.5 degrees.
4. A angle's supplement is basically 180 - (angle measure), because you are finding the angle that when formed with the original angle creates a 180 degree angle. Thus, the supplement angle would be 180 - 47 which is 133 degrees.
5. The angles 115 and (5x-10) create a 180 degree angle, which means that 115 + (5x-10) = 180. Thus, x = 15.
Answer:
5. The angles 115 and (5x-10) create a 180 degree angle, which means that 115 + (5x-10) = 180. Thus, x = 15.

Kristen wants to ask the managers of the fast food restaurants in a large city "How do you retain employees?" What condition must be true to justify surveying only a sample of the managers instead of surveying the entire population of managers?
The population is small.
The population is diverse.
The population is not the target of the survey question.
The population is expensive and time-consuming to survey.
I believe it is "The population is expensive and time-consuming to survey"
It is a large population, and conducting a census would be challenging.

no links or i'll hit you with the chancla .
Answer:
x = 34
Step-by-step explanation: Because it is a supplementary angle, it amounts to 180 degrees, so the equation is 4x+10+x=180. Use basic algebra from there.
The chalk circle around the pitcher's mound has a diameter of 16 ft. What is the area of the pitcher's circle?
Answer:
The area is approximately 201.06
Step-by-step explanation:
If you use the equation pi r^2, then we will get the answer. Since the diameter is double the radius, we should know that the radius is 8ft. Then we do the math and get the answer above.
Answer: A≈201.06ft²
Step-by-step explanation:
How to Calculate Diameter?
Diameter = Circumference ÷ π (when the circumference is given)
Diameter = 2 × Radius (when the radius is given)
Diameter = 2√[Area/π] (when the area is given)
