Answer:
No, proportional relations are of the form,

Step-by-step explanation:
The given equation is

This is an equation in the form:

since we can rewrite to get:

This equation has a non-zero y-intercept and does not pass through the origin.
A proportional relation, will have a zero y-intercept and pass through the origin.
Therefore a proportional relation is of the form,

The differnce of 2 perfect cubes
remember
a³-b³=(a-b)(a²+ab+b²)
so
11 14j+13j=48j 27j=48j subtract 27 from both sides j=11
Answer:
it is orthogonal
Step-by-step explanation:
if you do the dot product.
U dot V = 0
(3 times 0) + (0 times 6 ) = 0
0 + 0 = 0
therefore it is orthogonal.
the dot product says that if u dot v equals zero, then you can say that it is orthogonal.
