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.
Answer:
240 square units
Step-by-step explanation:
rectangle= 20x10=200
triangle= 1/2(4)(20)=40
200+40=240
3 + 5 = 8
8 - 5 = 3
3 - 3 = 0
Answer:
maybe 3 ?????
