A proportional relationship is described by the equation
... y = k·x
The point (x, y) = (0, 0) is <em>always</em> a solution to this equation.
_____
In short, if the relationship is proportional, its graph will go through the origin. If the graph does not go through the origin, the relationship is not proportional.
___
Note that this is true if the domain includes the origin. You can have y = kx <em>for x > 10 </em>and the graph will <em>not</em> go through the origin because the function is <em>not defined</em> there.
the second option
Step-by-step explanation:
root 4 16 is 2
root 4 powers mean divide by 4
Answer: Yes that's correct
Work Shown:
(-1)^2-(-2-(9-1))
1-(-2-(8))
1-(-2-8)
1-(-10)
1 + 10
11
Note that (-1)^2 = (-1)*(-1) = 1, and subtracting a negative turns into a positive.
Answer:
A
Step-by-step explanation:
The per capita income is the income of a person in a nation. The per capita is calculated by dividing the gross income of the nation by total population.
Let
Pci = Per Capita Income
I = Total income
and
P = Total population
Then,
Pci = I/P
