Two angles are supplementary if their sum is 180 degrees. One angle measures two times the measure of a smaller angle. If x repr

Serjik [45]

The smaller angle is 60 degrees and the larger angle is 120 degrees.
x+2x = 180, 3x=180, so x = 60 and 2x = 120.

What is the slope given: (5,2)&(9,-6)

Paul [167]

Answer:

The slope is -2

Step-by-step explanation:

To find the slope we do y2 - y1 / x2 - x1 or in this case, -6 - 2 / 9 - 5

Next, u solve -6 - 2 = -8 and 9 - 5 = 4

So we get -8/4 or simplified -2/1 or -2

The slope is -2

Hope that helps u! :)

Assume that f is continuous on [-4,4] and differentiable on (-4,4). The table gives some values of f'(x) x: -4, -3, -2, -1, 0, 1

kondaur [170]

$f$ will be increasing on the intervals where $f'(x)>0$ and decreasing wherever $f'(x)$ . Local extrema occur when $f'(x)=0$ and the sign of $f'(x)$ changes to either side of that point.

$f'(x)$ is positive when $x$ is between -4 and some number between -2 and -1, and also 2 (exclusive) and 4, so you can estimate that $f(x)$ is increasing on the intervals [-4, -2] and (2, 4].

$f'(x)$ is negative when $x$ is between some number between -2 and -1, up to some number less than 2. So $f(x)$ is decreasing on the interval [-1, 1].

You then have two possible cases for extrema occurring. The sign of $f'(x)$ changes for some $x$ between -2 and -1, and again to either side of $x=2$ .
