Answer:
a. Arithmetic
b.
c.
Step-by-step explanation:
A sequence is arithmetic when the difference between one term and the next is a constant. On the other hand, a sequence is geometric when the next term is found by multiplying the previous by a constant.
In this case, the next term of the sequence can be found by adding $15. Therefore, the sequence is ARITHMETIC ✔️
The recursive formula will be the following:
The explicit formula is the following:
Answer: C) All real values of x such that
In other words, x must be 0 or smaller.
===================================================
Explanation:
The reason why is because we must make the stuff under the square root to never be negative. We must make -2x be 0 or larger.
So,
As an example, if x = -2, then -2x = -2(-2) = 4 is positive. Applying the square root to a positive number is valid.
But if x = 5, then -2x = -2*5 = -10 is under the square root, which is not allowed.
Answer:
Step-by-step explanation:
In algebra , We use algebraic expression to represent word phrase.
For example : 7 is added to p is written as " "
-8 is multiplied by p is written as " "
The statement : Suzy found the difference of x and 4 and then divided by 2.
First we express the difference of x and 4 as
Then, we express entire statement : "difference of x and 4 and then divided by 2" =
Hence, the algebraic expression to represent this word phrase:
