Answer:
(r+s)÷3
Step-by-step explanation:
the sum of r and s - r+s
the quotient- ÷
by 3
3z-4=6z-17
-3z-4=-17 (subtracted the 6z from both sides)
-3z=-13 (added the 4 to both sides)
z=
(divided both sides by -3z)
z=
Answer:
Symmetric property
Step-by-step explanation:
In this question, we are given a set of options to choose the correct answer from which gives the definition of the property in the question.
The correct answer here is the symmetric property. So why is this correct?
In proper terms, we refer to this property as the symmetric property of congruence.
It is a way of referring to the fact that when writing the way two congruent angles are equal to each other by the property of congruence, we can move in either of the two directions.
Either way we write, we are absolutely correct to indicate that both angles are equal due to the property of congruence.
The answer is sequence I (choice A)
The common ratio is r = 1 because we multiply each term by 1 to get the next term. No change happens when we multiply any number by 1. Another way to find the common ratio is to pick any term and divide it by its previous term.
----------------------------------
Choice B is not the answer because (1/5) divided by (1/4) = 0.2/0.25 = 0.8
and because (1/6) divided by (1/5) = 0.833 approximately. We don't get the same value each time. So the common ratio doesn't stay the same.
Choice C is not the answer either since most of the terms are positive but the -4 in slot 3 is not positive. If it was positive, then the common ratio would be 4 and this sequence would be geometric. If the terms alternated between positive and negative, then it would work as well (r would be r = -4)
Choice D has alternating terms of positive and negative, but there's no change in absolute value. There is no growth or decay as this the terms effectively stay the same. So there is no common ratio. This is why we can rule out choice D.
