Yeah that is correct. 3/4 is equal to .75
Solve for c :
x⁴ + cx² + 100 = 0
cx² = -(x⁴ + 100)
c = - (x⁴ + 100)/x²
If x = 0, the right side is undefined and c would have no solution.
Answer:what is the question ?
Step-by-step explanation:
The for any number n>1 is |(3/4+2/3i)^n| greater than 1 after simplifying the complex number.
<h3>What is a complex number?</h3>
It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
We have a complex number:

Here n>1
Plug n = 2

= 145/144
= 1.0069
Which is greater than 1.
Thus, the for any number n>1 is |(3/4+2/3i)^n| greater than 1 after simplifying the complex number.

Elimination
first i would divide the second equation by -2.
x - y = -2
-x- 2y = -19
the x is eliminated.
-3y = -21
divide each side by -3.
y = 7
plug 7 in for y to solve for x
x-7 = -2
x = 5
(5,7)
