There are 4 terms in the world of *Mathematical proof*
Lemma, Proposition, Corollary and Theorem.
There is no difference between a lemma,
proposition, theorem, or corollary - they are all claims waiting to be proved. However, we use these terms to suggest different levels of importance and difficulty. A lemma is an easily proved claim which is helpful for proving other propositions and theorems, but is usually not particularly interesting in
its own right. A proposition is a statement which is interesting in its own right, while a theorem is a more important statement than a proposition which says something definitive on the subject, and often takes more effort to prove than a proposition or lemma. A corollary is a quick consequence of a proposition or theorem that was proven recently
Hi Brainiac
y=2x-3
y= 2x+5
Ok we need to solve y=2x-3 for y
Now substitute 2x-3 for y in y=2x+5
y=2x+5
2x-3=2x+5
Add -2x
2x-3-2x=2x+5-2x
-3=5
Add 3
-3+3=5+3
0=8

Answer:
x = ln(21)/ ln(4), Decimal Form: 2.19615871
Step-by-step explanation:
This is pretty complex math for middle school with logarithms and what not. Make sure you typed the problem in correctly. If you did, I guess that's your answer.
The amount of lines of symmetry of a shape is equal to the number of sides that shape has.
A heptagon has 7 sides, so, there are 7 lines of symmetry.
Best of Luck!
