Answer:
4
Step-by-step explanation:
The common ratio r of a geometric sequence is obtained by dividing a term by its preceding term as follows:
1) 4/1=4
2) 16/4=4
for this sequence the common ratio
r=4
Answer:
Factor the numerator and denominator and cancel the common factors.
20
Step-by-step explanation:
The solution of the equation are as follows:
x = 6 and y = -5
<h3 />
<h3>How to solve the system of equation?</h3>
4x + 5y = -1
-5x - 8y = 10
Therefore,
20x + 25y = -5
-20x - 32y = 40
-7y = 35
y = -5
Hence,
4x + 5(-5) = -1
4x - 25 = -1
4x = -1 + 25
4x = 24
x = 24 / 4
x = 6
