Answer:

1: Subtract 9 from each side

2: divide each side by 2

3: add 11 to each side

4: divide each side by 4

Step-by-step explanation:

in order to successfully start the equation, you cannot outright divide both sides by 2, so you have to subtract the solo value from both sides to create a balanced equation. Then, you divide both sides by 2 to get rid of the parenthesis, and add 11 to each side in order for the variable to be on its own, and divide each side by 4 to find the value of x

Whitepunk [10]

Answer:

$(6\sqrt{3},\,\frac{5\pi}{6})$

Step-by-step explanation:

The radius r can be found from the relationship

$r^2=x^2+y^2\\r^2=(-9)^2+(3\sqrt{3})^2\\r^2=81+27=108\\r=\sqrt{108}\\r=6\sqrt{3}$

The point is in Quadrant II (-, +), so use the inverse cosine function to find the angle.

$\cos{\theta}=\frac{x}{r}=\frac{-9}{6\sqrt{3}}\\\cos{\theta}=-\frac{9}{6\sqrt{3}} \cdot \frac{\sqrt{3}}{\sqrt{3}}\\\cos{\theta}=-\frac{9\sqrt{3}}{6\cdot3}\\\cos{\theta}=-\frac{\sqrt{3}}{2}\\\\\cos^{-1}\frac{-\sqrt{3}}{2}}=\frac{5\pi}{6}$

If four times a number plus 3 is 11, what is the number? a. 4 bm 2 c. 16 d. 5

goblinko [34]

Answer:

B. 2 (Second Option)

Step-by-step explanation:

Four times: ⇒ 4

Number:⇒ y

4y+3=11

Subtract by 3 both sides of equation.

4y+3-3=11-3

Simplify.

11-3=8

4y=8

Divide by 4 both sides of equation.

4y/4=8/4

SImplify, to find the answer.

8/4=2

y=2 is the correct answer.

2 is the correct answer.
