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.
D
19/50 multiply 2 on numerator and denominator it becomes 38/100
38/100 = 0.38 since 38/100 is 38 divide by 100 which is 0.38
X=12
First you would combine like terms 7+3=10
Then you would have 10 +5x =70
Subtract 10 from both sides 10-10 & 70-10
That will leave you with 5x=60
Divide 5 from both sides 5x/5 & 60/5
Answer will be x = 12
