Amaya used these steps to solve the equation 8x+4=9+4(2x−1). Which choice describes the meaning of her result, 4=5?
2 answers:
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.

Answer:
x'-5x=0, or x''-25x=0, or x'''-125x=0
Step-by-step explanation:
The function is infinitely differentiable, so it satisfies a infinite number of differential equations. The required answer depends on your previous part, so I will describe a general procedure to obtain the equations.
Using rules of differentiation, we obtain that . Differentiate again to obtain,
. Repeating this process,
.
This can repeated infinitely, so it is possible to obtain a differential equation of order n. The key is to differentiate the required number of times and write the equation in terms of x.
