Answer:
For k = 6 or k = -6, the equation will have exactly one solution.
Step-by-step explanation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots 
such that 
, given by the following formulas:
If 
, the equation has only one solution.
In this problem, we have that:
So
We will only have one solution if . So
For k = 6 or k = -6, the equation will have exactly one solution.
Well z=5 and z=-7 hope this is the correct answer
Answer:
75%
Step-by-step explanation:
Since it's saying less than 7, that tells you-you have 6 numbers less than 7. I put 6/8 which converts to 75%
The correct first step would be to gather all like terms together:
2x-4x-x = 7+ 5
-3x = 12
x = -4
