Answer:
reduced to the simplest form is 
Step-by-step explanation:

First, rearrange the fractions so that they have the same denominator. We do this by finding the common multiple of 3 and 6 and multiplying the numerators by the number of times it takes to get to the denominator when multiplying.

Now, since 7/6 is negative, then it would just be like subtracting 7/6 from 10/6.

Now, all we have to do is reduce the fraction 3/6.

So, your final answer would be 
The proportion that does not represent corollary 1 or
corollar2 of the right triangle altitude theorem is C. c / d = d / e
<span>Because c in the bigger triangle is the hypotenuse while d
is not the hypotenuse in the smaller triangle. </span>
0,0 i think lol but good luck
Substitution method and elimination method. And how does it relate to setting equal to each other? It's where the two graphs intersect is where they have in common
