Answer:
Real values of x where x < -1
Step-by-step explanation:
Above the x-axis, the function is positive.
The function is decreasing when the gradient is negative.
The function has a positive
coefficient, therefore the vertex is a local minimum;
This means the gradients are negative before the vertex and positive after it;
To meet the conditions therefore, the function must be before the vertex and above the x-axis;
This will be anywhere before the x-intercept at x = -1;
Hence it is when x < -1.

Answer:
x ≥12
Step-by-step explanation:
-3x ≤ -36
Divide each side by -3, remembering to flip the inequality
-3x/-3 ≥ -36/-3
x ≥12
Hi!
The answer to your question is 9.75 minutes
Here is the math to prove it:
9+11+3+14+14+7+14+6=78
Now you will take 78 and divide it by 8
This is because when finding the mean you add all of the given number together and then divide them by the amount of number added together.
78/8=9.75
Thus, your answer is 9.75 minutes
I hope this helped!
Have a wonderful day/night!
God bless!
