What is the significance of a dashed and solid line on an inequality function?

Nadya [2.5K]

Answer:

Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.

I need help with this equation. Please solve for k

Levart [38]

Hey there!

18 = -k + 3

-k + 3 = 18

-1k + 3 = 18

SUBTRACT 3 to BOTH SIDES

-1k + 3 - 3 = 18 - 3

SIMPLIFY IT!

-1k = 18 - 3

-1k = 15

DIVIDE -1 to BOTH SIDES

-1k/-1 = 15/-1

SIMPLIFY IT!
k = 15/-1

k = -15

Therefore, the answer is: k = -15

Good luck on your assignment & enjoy your day!

Which of the following best explains why tangent StartFraction 5 pi Over 6 EndFraction not-equals tangent StartFraction 5 pi Ove

I am Lyosha [343]

Using the tangent equation and reference angles, it is found that the correct option is given by:

The angles do not have the same reference angle.

<h3>What is the tangent of angle?</h3>

It is given by the sine <u>divided by the cosine</u>. For angles that are not on the first quadrant, we can also finding their tangent by using their reference angles, considering the signs according to the quadrant of the angles.

Angle $\frac{5\pi}{6}$ is on the second quadrant, and the reference angle is:

$\pi - \frac{5\pi}{6} = \frac{6\pi}{6} - \frac{5\pi}{6} = \frac{\pi}{6}$

Angle $\frac{5\pi}{3}$ is on the fourth quadrant, and the reference angle is:

$2\pi - \frac{5\pi}{3} = \frac{6\pi}{3} - \frac{5\pi}{3} = \frac{\pi}{3}$

Different reference angles, hence different values for sine and cosine, and different value for the tangent.

Both $\frac{5\pi}{3}$ and $\frac{5\pi}{6}$ are positive measures, hence the only reason is the difference reference angles.
