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: The last line is the answer
12 - 4x <u><</u> 20
20 - 12 = 8
-4x = 8
-4/4 = 8/-4
x = -2
New inequality: x <u>></u> -2

1. D
2. C
3. B
4. A
Step-by-step explanation:
just match up the number y is on the right side and x on the left side like this (x,y)
Answer:
Step-by-step explanation:
You can set this up by reversing it.
(9+4)- (x/2)
(13)-(x/2)
(13)-(2x)
=11x
-4x-2y = 16
2y = -4x-16
Get one variable alone on both equations
-4x - 16 = 2y
-4x - 16 = 2y
You'll realize that they're the same equation.
Use substitution
-4x-16 = -4x-16
0 = 0
x = all solutions
Use x = all solutions in an earlier equation to find y
-4x - 16 = 2y
SInce x can be all solutions y is also all solutions
y = all solutions
