Use the power rule,
d(x^n)/dx = nx^(n-1)

So
f(x)=x^7-2x^3-9x
f'(x)=7x^6-6x^2-9

Subtract five from three times a number and the result is equal to the number plus five. find the number.

allsm [11]

3(x)-5=x+5
3x=-5+5+x
3x=x
0=x
because 3x=x is basically would make each part into 0 which would end up the same.

Which inequality is shown in this graph

Katena32 [7]

ANSWER

$y \leqslant - 2x - 2$

EXPLANATION

The boundary line passes through (-2,2) and (0,-2).

The slope of this line is

$m = \frac{ - 2 - 2}{0 - - 2}$

$m = \frac{ - 4}{2} = - 2$

The y-intercept is , c=-2.

The slope-intercept form of this line is given by;

$y = mx + c$

We substitute values to obtain;

$y = - 2x - 2$

Since the lower half-plane is shaded the required inequality is

$y \leqslant - 2x - 2$

The sum of the angle measures of a polygon with s sides is 2340. find s.

marta [7]

Answer:

s = 15.

Step-by-step explanation:

The formula for a polygon with s sides is:

Sum of the angles = 180(s - 2) so we have:

180(s - 2) = 2340

180s - 360 = 2340

180s = 2700

s = 15
