The image of the transformation is missing so i have attached it;

Answer:

Option C - The transformation is not isometric because the lengths did not remain the same.

Step-by-step explanation:

Transformation means that it preserves the length of  the original figure which means that it is a distance preserving transformation.

Now, from the image of the question attached, the two figures can be said to be isometric if they are congruent.

Now, for the figure displaying the transformation we can see that the size of the original figure has changed.

We can see that the figure is dilated by a scale factor of 2 as each of the sides of the polygon which is a trapezoid is increased by a factor of 2.

Due to the fact that the lengths of sides of the original figure and transformed figure are are not same, we can say that the lengths are not preserved.

Thus, the transformation is not isometric because the lengths did not remain the same.

What’s the x-intercept of the graph of <br> 5x-4y= 20
viva [34]

The x-intercept of the graph is (4 , 0)

Step-by-step explanation:

Let us revise the meaning of x-intercept and y-intercept

  • x-intercept means value x when y = 0
  • That means the graph intersects x-axis at point (a , 0), where a the value of x when y = 0
  • y-intercept means value of y when x = 0
  • That means the graph intersects y-axis at point (0 , b), where b is the value of y when x = 0

∵ 5x - 4y = 20 is the equation of the graph

- To find x-intercept substitute y by 0

∵ y = 0

∴ 5x - 4(0) = 20

∴ 5x - 0 = 20

∴ 5x = 20

- Divide both sides by 5

∴ x = 4

The x-intercept of the graph is (4 , 0)

Find the equation of the circle in standard form for the given center (h, k) and radius r: (h, k) = (5, 4), r = 2
kenny6666 [7]
If cente ris (h,k) and radius is r then
equatn is (x-h)^2+(y-k)^2=r^2

so


center (5,4)
r=2
h=5
k=4

(x-5)^2+(y-4)^2=2^2
(x-5)^2+(y-4)^2=4

first option
