4x-10= 2x-5
100-30x= -15x+50
I didn’t know which one you wanted me to do so I just did both!
Hope this helps!!!
Reflection does not preserve orientation.
Dilation (scaling), rotation and translation (shift) do preserve it.
<span>Postulates and conjectures are similar in that they are both used in mathematical proofs. The difference between them is that whilst a conjecture is a opinion that is put forward without proof, and that simply represents a belief, a postulate it something that is assumed true (but still does not have any proof behind it).</span>
Answer:
Can you give us more information?
Step-by-step explanation:
Geometric sequence
an=a1(r)^(n-1)
a1=first term
r=common rati
common ratio is 4 because 3 times 4=12
first term is 3
an=3(4)^(n-1)
9th term
a9=3(4)^(9-1)
a9=3(4)^8
a9=3(65536)
a9=196608
answer is 4th option
