Answer:
The set of transformations has been performed on triangle ABC is dilation by a scale factor of 2 followed by reflection about the x-axis
Step-by-step explanation:
Let us write the vertices of Δ ABC
∵ Vertex A = (-2, -1)
∵ Vertex B = (0, 0)
∵ Vertex C = (1, -3)
Let us Write the vertices of Δ A'B'C'
∵ Vertex A' = (-4, 2)
∵ Vertex B' = (0, 0)
∵ Vertex C' = (2, 6)
Let us find the scale factor k between the x-coordinates of the points and their images.
∵ -4 = k (-2) ⇒ Divide both side by -2
∵ 
= 
∴ 2 = k
∴ The scale factor of a dilation is 2
∵ The signs of the y-coordinates of the images are the opposite of
the signs of the y-coordinates of the points
∴ The triangle is reflected about the x-axis
∴ The set of transformations has been performed on triangle ABC
is dilation by a scale factor of 2 followed by reflection about the x-axis
Answer:
Step-by-step explanation:
Answer:
First take 0.23 as 0.23/1
Then Multiply the numerator and denominator by any number, Let us say 100
So it becomes,
0.23 x 100/100
=> 23/100
Option D:
is positive product.
Solution:
<em>If the negative sign is in even number of times then the product is positive.</em>
<em>If the negative sign is in odd number of times then the product is negative.</em>
To find which product is positive:
Option A:
Here, number of negative signs = 3
3 is an odd number.
So, the product is negative.
Option B:
Here, number of negative signs = 3
3 is an odd number.
So, the product is negative.
Option C:
Here, number of negative sign = 1
1 is an odd number.
So, the product is negative.
Option D:
Here, number of negative sign = 2
2 is an odd number.
So, the product is positive.
Hence option D is the correct answer.
is positive product.
I think the answer would be 343?
