Answer:
(p+e)/(r-n) = x
Step-by-step explanation:
p + nx=rx-e
Add e to each side
p +e+ nx=rx-e+e
p +e+ nx=rx
Subtract nx from each side
p +e+ nx - nx=rx-nx
p+e = rx -nx
Factor out x
p+e = x(r-n)
Divide each side by (r-n)
(p+e)/(r-n) = x(r-n)/(r-n)
(p+e)/(r-n) = x
Answer:
A) Reflection.
Step-by-step explanation:
From the figure shown, we can see that the blue triangle is flipped about the x-axis to form the red triangle.
When an object is flipped about a line, then this transformation is called reflection about that line.
Thus, we can say that reflection is taking place in the figure shown in which the x-axis is acting like a mirror. The blue triangle is the pre-image and the red triangle is the image after reflection.
The reflection about x-axis is given by:
We can check the co-ordinates of the triangles and confirm the the transformation occurring
Points of pre-image triangle:
Points of image triangle
Thus, the transformation is reflection.
Answer:
42 and 44
Step-by-step explanation:
The even numbers are numbers which can be written as 2n where n is any integer number.
Therefore, two consecutive numbers would be "2n" and "2n + 2"
We then have that
2n + (2n+2) = 86
4n + 2 = 86
4n = 84
n = 21
And the even number 2n is 2(21) = 42.
(We can verify this answer by doing 42 + 44 = 86)
