Answer:
x = -8
Step-by-step explanation:
- 7x+23 = 4x-1
- 3x + 23 = -1
- 3x = -24
- x = -8
Hello!
2.78 * 6 = 16.68
I hope this helps, and have a nice day!
The Answer is C because when u divide 8 on both sides the sign of this < would switch to > since 32 is a negative number and when u divide -32 by 8 u get x>-4

Answer:
no real solutions; k = ±i(2/3)√15
Step-by-step explanation:
If k is one of the roots, then substituting it for x will satisfy the equation:
k -4k -20/k = 0
Multiplying by k gives ...
-3k^2 -20 = 0
k^2 = -20/3 = -6 2/3
There are no real values of k such that this is true.
__
If we allow k to be imaginary, then ...
k = ±i√(20/3) = ±i(2/3)√15
Possible imaginary values of k are ±(2/3)√15.
