<span>We need to find the correct answer on the given choices:
If a >
0 and b < 0, then The answer is a + b > 0
let’s give a specific example:
let’s have a = 1
and b = .20
</span>
<span>Now,
let’s try calculating if our answer is correct.
Thus a + b > 0
=> a + b
=> 1 + .20
=> 1.20
and 1.20 is greater than 0.
=>Therefore 1.20 > 0 = a + b > 0</span>
Answer:
Step-by-step explanation:
1.5 * 13 = 19.5 dollars
0.50 = 20 - 1.5x where 0.50 is the amount of money he has left and x is the number of bottles of water he buys
The sequence that represents a geometric sequence can be seen in the 1st option and the 4th option in the image attached.
<h3>What is a geometric sequence?</h3>
A geometric sequence is a set of integers that follows a pattern in which the following term is determined by multiplying the previous one by a factor known as the common ratio (r).
or
From the options given, the options that have geometric sequences are:
r = (3/8)/(3/16) = (3/4)/(3/8) = 2 (proves that it is a geometric sequence)
- 3, 9, 27, 81
- r = 9/3 = 27/9 = 3 (proves that it is a geometric sequence)
