Answers
Step by step
4x -2(x - 2) = -9 +5x -8
Distribute
4x -2x +4 = -9 +5x -8
Combine
2x + 4 = 5x -17
Subtract 5x from both sides to isolate variable
2x -5x +4 = 5x -5x -17
Combine
-3x +4 = -17
Subtract 4 from both sides to combine constants
-3x +4 -4 = -17 -4
Combine
-3x = -21
Divide both sides by -3 to solve
-3/-3 x = -21/-3

Answer: D. 61 in²
Step-by-step explanation:
This problem is asking for us to solve the area of the given circle. We will use the formula and solve.
Please note that the formula asks for the radius and 9 in is the diameter. Since the radius is half the diameter, we will divide 9 in by 2 for a radius of 4.5 in.
A = πr²
A = π(4.5 in)²
A ≈ 63.62 in²
The closest option they give to solve this problem is D. 61 in²

Geometry
Answer with a proper explanation
Answers
Answer:
15 sides
Step-by-step explanation:
As we know the full angles of a polygon is 360°
And
Each side has angle 24°
So,
n = 360/24
n = 15 sides
I hope my answer helps you.
The polygon has 5 sides.
Step-by-step explanation:
Given in the diagram, the angle between the ends of each side is given i.e. 24degrees between ends of a side from the centre. Or it can also be said that each side of the polygon subtends an angle at the centre 'O' i.e. each 24*.
=> We know that sum of angles around a point = 360*, so sum of angles around centre = 360*
And 24* in the centre subtends a side of the polygon;
Using the logic - no. of sides = 360*/24* = 15 = 15 sides

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answers
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.
If you draw a dilation of triangle ABC with center (0,0) and a scale factor of 1.5, what would be the vertices of the new triangle A’B’C’.
Answers
Answer:reminder
Dilations are enlargements
(or reductions)!!
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.
• A dilation that creates a larger image is called an enlargement.
• A dilation that creates a smaller image is called a reduction.
• A dilation stretches or shrinks the original figure.
dipic1
• A description of a dilation includes the scale factor (or ratio) and the center of the dilation.
• The center of dilation is a fixed point in the plane.
• If the scale factor is greater than 1, the image is an enlargement (a stretch).
• If the scale factor is between 0 and 1, the image is a reduction (a shrink).
• If the scale factor is 1, the figure and the image are congruent
Step-by-step explanation:
Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two.
Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2).
Dilations involve multiplication!
Dilation with scale factor 2, multiply by 2.
(x, y) → (2x,2y)
bullet Dilation scale factor ½:
dilX2
Starting with quadrilateral ABCD (blue), draw the dilation image of the quadrilateral with a center at the origin and a scale factor of ½.
Each vertex of ABCD is multiplied by ½.
Dilation with scale factor ½, multiply by ½.
(x, y) → (½x, ½y )
In this problem, the center of the dilation is NOT at the origin.
bullet Dilation not at origin:
dilX3
Starting with rectangle ABCD (green), draw the dilation image of the rectangle with the center of dilation at point A and a scale factor of 1/3
Notice that point A and its image are the same.
You must observe the distances from the center of the dilation at point A to the other points B, C and D. The dilation image will be 1/3 of each of these distances.
AB = 6, so A'B' = 2.
AD = 9, so A'D' = 3. Now, draw the image rectangle.
FYI:
dilmathHyp
For a dilation not at the origin,
measure the distances.
Dilations and Similarity:
The term similar (or similarity) can be defined using the language of transformations.
def
Two figures are similar if one is the image of the other under a transformation from the plane into itself that multiplies all distances by the same positive scale factor. That is to say, one figure is a dilation of the other.
dil Sim M
Step-by-step explanation:
the vertices of the new triangle A’B’C’.
\(A'(6,-3)\\B' (-3,-3)\\C'(-3,3)\)
Given
A diagram of a triangle ABC with center (0,0) and scale factor of 1.5
Lets write the vertices of A, B and C
A is (4,-2)
B is (-2,-2)
C is (-2,2)
Now we use the scale factor . Multiply the scale factor with x and y to get vertices of new triangle A'B'C'
\(A is (4,-2)\\A' (4 \cdot 1.5, -2\cdot 1.5)\\A' (6,-3)\\\\\\B is (-2,-2)\\B' (-2 \cdot 1.5, -2\cdot 1.5)\\B' (-3,-3)\\\\\\C is (-2,2)\\C' (-2 \cdot 1.5, 2\cdot 1.5)\\C' (-3,3)\\\)
