Answer: Non proportional</h3>
Proportional equations are of the form y = kx, for some fixed constant k. The k value is the constant of proportionality.
The +100 at the end is why we don't have a proportional equation.
Visually all proportional equations go through the origin, meaning the lines have y intercept of 0. For y = 230x+100, the y intercept is 100.
The only whole number that isn’t a natural number is 0
We are given expression: 
.
Tyna simplified the given expression to 
.
Explanation: In order to simplify , Tyna need to simplify rational expression 
.
On dividing top and bottom by 3, we get 
.
Which Tyna got correct.
Now she need to simplify 
.
<em>On applying quotient rule of exponents, we need to subtract the exponents of x's.</em>
So, it would be 
.
<h3>So, the final answer should be
.</h3><h3>Therefore, Tyan forgot to add exponent to x.</h3><h3>The exponent of x should be 5.</h3>
We need two definitions.
Two shapes are congruent if you can turn one into another using translation, rotation, and reflection.
Two shapes are similar if you rescale one them into a shape that is congruent to the other.
We can conclude from this that in euclidian geometry all circles are similar.
We can shrink the first circle to get the second one.
Scale factor would be 1/3 as circle 1 has the radius that is 3 times the radius of circle 2.
