X/-9 =3<br>I dont understand this.

STatiana [176]

Final Answer: $x = -27$

Steps/Equations:

Question: $\frac{x}{-9} = 3$

Step 1: Move the negative sign to the left side.

$-\frac{x}{9} = 3$

Step 2: Multiply both sides by $3$ .

$-x = 3 * 9$

Step 3: Simplify $3 * 9$ to $27$ .

$-x = 27$

Step 4: Multiply both sides by $-1$ .

$x = -27$

~I hope I helped :)~

Find the exact value of csc ø, if cos ø= 1/9; 180° less ø less than 270°

Iteru [2.4K]

Answer:

The answer to your question is: the first option - 9/ $\sqrt{80}$

Step-by-step explanation:

Process

cosФ = adjacent side / hypotenuse

-1/9 = adjacent side / hypotenuse

adjacent side = -1 hypotenuse = 9

c² = a² + b²

b² = c² - a²

b² = 81 - 1

b = $\sqrt{80} \\$ b = opposite side

But b is negative because we are in the third quadrant.

b = - $\sqrt{80}$

Finally csc Ф = hypotenuse / opposite side

csc Ф = - 9 / $\sqrt{80}$

Step-by-step explanation:

5ˣ(2x + 3) + 2 (2x + 3 )

10x² + 15x + 2(2x + 3 )

10x² + 15x + 4x + 6

= 10x² + 19x + 6
