The y intercept is 0, and the slope is 5x.
Equation: y = 5x +0.
-5/-7 = 5/7 = 0.71428577142857... The decimal form of the fraction never ends, so 5/7 is not a rational number
Answer:
x = 10
Step-by-step explanation:

The volume of the original cone is multiplied by 27
<h3><u>Solution:</u></h3>
We have been given that the height and radius of a cone are each multiplied by 3.
We need to find what effect it has on the volume of the cone.
<em><u>The volume of the original cone is given as follows:</u></em>

Now, the radius and height are multiplied by 3.
Therefore, the new radius is ‘3r’ and the new height is ‘3h’.
Hence the new volume is

original volume of cone x 27 = volume of new cone
Therefore, the original volume of cone is multiplied by 27
Answer:
still (0,9)
Step-by-step explanation:
The point is already on the y axis, so negating the x coordinate (0) doesn't change anything. 0=-0.
