Therefore, as a result of congruency along the line DE, one triangle is simply the other triangle reflected and DE = 1/2CB is proven.
What is Congruency?When two shapes or items are similar in shape, or when one is a perfect mirror of another and is similar in size and shape, they are said to be congruent in geometry. Two forms are congruent if their dimensions match. It is also true that mirror representations of two forms are the same if different systems are congruent. Objects with exact matching dimensions and shapes are referred to be matches. The forms hold true regardless of rotation, flipping, or reversal. Use the to create two circles.
Here,
When ΔABC and ΔDEF are used,
∠ABC = ∠ DEF (given)
AB = DE, and (same length)
∠BAC = ∠FED (same angle)
The ΔABC and ΔDEF triangle is similar
Thus , as there are similar we can say that:
=> DE = 1/2CB
As a result, along the line DE, one triangle is simply the other triangle reflected and DE = 1/2CB is proven.

Answers
The coordinate of the point F' after dilation will be (1, -1). Then the correct option is D.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
The coordinate of point F is (2, -2). And the scale factor is 1/2. Then the coordinate of the point F' after dilation will be calculated as,
⇒ (1/2) × (2, -2)

Which points are reflections of each other across both axes?(–2, 8) and (2, –8)(–7, –1) and (–7, 1)(5, –6) and (–5, –6)(4, –3) and (–3, 4)
Answers
The points (–2, 8) and (2, –8) are reflections of each other across both axes. This can be seen by taking their coordinates and plugging them into the reflection formula, which is (x, y) → (–x, –y).
When we plug in the coordinates for the first point, we get (–2, 8) → (–(–2), –(8)) = (2, –8). This is the coordinates of the second point, so they are reflections of each other.
The points (–7, –1) and (–7, 1) are also reflections of each other across both axes. Using the same reflection formula, we get (–7, –1) → (–(–7), –(–1)) = (7, 1), which are the coordinates of the second point.
The points (5, –6) and (–5, –6) are reflections of each other across both axes. Applying the reflection formula, we get (5, –6) → (–(5), –(–6)) = (–5, 6), which are the coordinates of the second point.
Finally, the points (4, –3) and (–3, 4) are reflections of each other across both axes. Using the reflection formula, we get (4, –3) → (–(4), –(–3)) = (–4, 3), which are the coordinates of the second point.

Christine went shopping and bought each of her ten nephews a gift, either a video costing $14.95 or a CD costin $16.88. She spent $161.08 on the giftsHow many videos and how many CDs did she buy?
Answers
Therefore , the solution to the given problem of linear equation comes out to be we bought 6 videos and 3 CDs.
Define a linear equation.The term "linear" refers to any function that has the algebraic form y=mx+b. m is the y-intercept, while B is the slope. The previous sentence contains a two-variable linear equation since both y and y are factors. Equations involving two variables are called bivariate equations. y + z = 2 and 3z - 6 + x = 3 are two of the many applications for linear equations. The equation y=mx+b, where m stands for the slope and b for the y-intercept, is referred to as a linear equation. The formula is Y=mx+b, where m denotes the inclination and b the y-intercept.
Here,
A collection of equations will be constructed.
Let V = the number of videos purchased.
C will stand for the quantity of purchased CDs.
Since there are eight nephews in all, and each nephew received either a video or a CD, the sum of the numbers of movies and CDs is nine.
So V + C = 9.
We are also aware of how much each CD and film cost and how much money was wasted.
So 14.95V + 16.88C = 140.34
Here, let's experiment with substitution.
Let's just solve for V since it doesn't matter whichever variable we do it for. V = 9 - C
Therefore, replace "V" in the second equation with "9-C," and the result will be 134.55 - 14.95C + 16.88C = 140.34 1.93C = 5.79 C = 3
You can add C = 3 straight into either of the original equations, though I believe I know which one is simpler for you.
V + 3 = 9
V = 6
So we bought 3 CDs and 6 videos.
Therefore , the solution to the given problem of equation comes out to be we bought 6 videos and 3 CDs.

p(x)=2x+2(x+4) to determine the perimeter of the flower box based on the width x in feet
Answers
Answer: The perimeter of the flower box can be determined by adding up the lengths of all four sides. In this case, we can see that the width of the flower box is represented by the variable x in feet, and the height is given as 2(x+4). To find the perimeter, we need to add up the lengths of the top and bottom (2x) and the left and right sides (2(x+4)). So, the perimeter P(x) can be expressed as:
P(x) = 2x + 2(x+4)
Simplifying this expression:
P(x) = 2x + 2x + 8
P(x) = 4x + 8
So the perimeter of the flower box is 4x+8 feet, based on the width x in feet.

Find two consecutive positive integers such that the square of the larger integer is 19 more than 9 times the smaller integer define your variables and write an equation HURRY HELP PLEASE SHOW STEPS
Answers
Answer:
9 and 10
Step-by-step explanation:
x = 1st positive integer
x+1 = 2nd positive integer
Solve for both x and x+1(x+1) is the next positive integer after x (Ex. 3 aka 2+1 is next integer after 2).
Larger Integer: x+1 ==> being squared
Smaller Integer: x ==> being multipled by 9
9x + 19 = (x+1)^2 ==> the square of (x+1) is 19 more that 9 multiplied by x.
9x + 19 = (x+1)(x+1) ==> simplify
9x + 19 = x(x+1) + 1(x+1) ==> distribute (x+1) to x and 1.
9x + 19 = (x*x + 1*x) + (1*x + 1*1)
9x + 19 = x^2 + x + x + 1 ==> simplify
9x + 19 = x^2 + 2x + 1
19 = x^2 - 7x + 1 ==> subtract 9x on both sides
Make one side of the equation equal to 0 so you can factor the equation:
0 = x^2 - 7x - 18 ==> subtract both sides by 19
0 = x^2 + 2x - 9x - 18 ==> 2x - 9x = -7x and 2 * (-9) = -18
0 = x*x + 2x - 9x - 18
0 = x(x + 2) - 9(x + 2) ==> factor
0 = (x - 9)(x + 2)
x - 9 = 0 x + 2 = 0
x = 9 x = -2
Out of x = 9 and x = -2, only x = 9 is positive.
Hence, x = 9 and x+1=10.
Hence, the answers are 9 and 10.

Longitudes: The vertical lines running north-south, join the two poles. They are called the meridians of longitude. They are spaced farthest apart at the equator and converge at a point at each pole.
Horizontal lines called latitudes are used to measure distances north or south of the equator. Vertical lines known as longitudes are used to determine the west or east of the meridian in Greenwich, England. Latitude and longitude work together to help cartographers, geographers, and others find specific locations on the globe.

In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”. But to compare the values, whether it is less than or greater than, different inequalities are used
Inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol. The expressions on both sides of an inequality sign are not equal. It means that the expression on the left-hand side should be greater than or less than the expression on the right-hand side or vice versa
If two real numbers or the algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then the relation is called an inequality.
