Answer:

\displaystyle -\frac{1}{3} ≥ y

Step-by-step explanation:

\displaystyle \frac{-3(5y - 4)}{-3} ≥ \frac{17}{-3}

5y - 4 ≤ –5⅔

+ 4 + 4

__________

\displaystyle \frac{5y}{5} ≤ \frac{-1\frac{2}{3}}{5} \\ \\ y ≤ -\frac{1}{3}

Whenever you divide\multiply by a negative, you reverse the inequality symbol.

* Use the zero-interval test [test point (0, 0)] to determine whether we shade the opposite portion [the portion that does not contain the origin] or the portion that DOES contain the origin. This is where we verify the inequality as false or true:

\displaystyle 0 ≰ -\frac{1}{3}

This is a false statement, so we shade the opposite portion of the line.

I am joyous to assist you anytime.

Answer:

The correct option is C ) 109.5°

Therefore,

m\angle E=109.5\°

Step-by-step explanation:

Given:

In Triangle DEF

d = 10

e = 18

f = 12

To Find

angle E = ?

Solution:

In Triangle DEF , Cosine Rule says

\cos E=\dfrac{f^{2}+d^{2}-e^{2}}{2fd}

Substituting the values we get

\cos E=\dfrac{12^{2}+10^{2}-18^{2}}{2\times 12\times 10}

\cos E=\dfrac{-80}{240}=-\dfrac{1}{3}

Therefore,

\angle E=\cos^{-1}(-0.3333)

m\angle E=109.5\°       ............As it is in Second Quadrant

Therefore,

m\angle E=109.5\°
