Answer:
No value of x makes the equation true.
Step-by-step explanation:
Here are the choices which are missing in the question:
a) Amaya made a mistake because 4 is not equal to 5
b) No value of x make the equation true.
c) All value of x make the equation true.
d) The solution is x= 4 or 5
Given equation is
Now, solving the equation:
distributing 4 with both 2x and -1
⇒
⇒
Subtracting both side by 8x
∴ 4=5
The result indicate that equation has the same result and x has no value.
The explicit formula for the geometric sequence is
Step-by-step explanation:
The formula of the nth term of a geometric sequence is
, where:
- a is the first term of the sequence
- r is the common ratio between the consecutive terms
The geometric sequence of is 6 , -2 ,
,
,
∵ = 6
∵
∵ = -2
∴
- Divide both term by 2 to simplify it
∴
∵
- Substitute the value of and r in the rule above
∴
