What is that is the derivative of
katovenus [111]

Answer:

see explanation

Step-by-step explanation:

differentiate using the power rule.

\frac{d}{dx}( ax^{n} ) = nax^{n-1} , thus

\frac{d}{dx}(x² - x + 3 ) = 2x - 1

x = 5 → 2(5) - 1 = 10 - 1 = 9

To find the value of x for minimum , equate \frac{d}{dx} to zero

2x - 1 = 0 , then

2x = 1 and

x = \frac{1}{2}

Solve the inequality(s)<br> 2c &gt; 2 <br> d/6 ≥ 1 <br> r + 9 ≤ 23
tatiyna
Divide both sides by 2 for the first one.
2c/2>2/2
c>1
simplify both sides for the second 1 
1/6d>=1
6*(1/6d).=(6)*(1)
d>=6
For the last one 
subtract 9 from both sides
r+9-9<=23-9   so  that r<=14
 Hope this helps!
