1. (5x-8)=(8x-17)
5x-8x=-17+8
-3x=-9
x=3

2. (3x+5) + (4x-7) =180
3x+5+4x-7=180
3x+4x=180-5+7
7x=182
x=26

Rus_ich [418]

Answer:

$\large\boxed{\theta=k\pi,\ k\in\mathbb{Z}}$

Step-by-step explanation:

$\sec\thets\cdot\sin\theta=0\iff \sec\theta=0\ \vee\ \sin\theta=0\\\\\sec\theta\neq0\ \text{for any value of}\ \theta\\\\\sin\theta=0\Rightarrow\theta=k\pi\ \text{where}\ k\in\mathbb{Z}$

Which correctly describes how the graph of the inequality 4x - 2y > 20 is shaded?

Phantasy [73]

First we need to express y in this inequality:
-2y > -4x + 20
-y > -2x + 10
y < 2x - 10

The line isn't solid because the "less" sign doesn't include equal in it.
Because the sign is "less than" the shaded part is Below the line.

Merging these 2 conclusion we get the answer:
below the dashed line.
