Y^2 − x^2 = 100 is that a function or no?

No, it is not an equation

Step-by-step explanation:

See attached graph:

No. If you solve it for , you have

So, given a certain value for , say , you have

So, you're associating two y-values for each x value. This implies that this is not a function.

the answer is c hope it

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
