Answer:

3x^2+4x=1

x(3x+4)=1

So, there is two x answers

1)x=1

2)3x+4=1 => x= -1

sattari [20]

Answer:

$x=0$

Step-by-step explanation:

$\frac{7}{3}(2x+3)+\frac{3}{4}(\frac{x}{5}-\frac{15}{2})=\frac{11}{8}$ <-- Given

$\frac{14}{3}x+7+\frac{3}{20}x-\frac{45}{8}=\frac{11}{8}$ <-- Distributive Property

$\frac{280}{60}x+7+\frac{9}{60}x-\frac{45}{8}=\frac{11}{8}$ <-- Find LCD of x-terms

$\frac{289}{60}x+7-\frac{45}{8}=\frac{11}{8}$ <-- Combine Like Terms

$\frac{289}{60}x+7=\frac{56}{8}$ <-- Add 45/8 to both sides

$\frac{289}{60}x+7}=7$ <-- Simplify Right Side

$\frac{289}{60}x=0$ <-- Subtract 7 on both sides

$x=0$ <-- Divide both sides by 289/60

Mark the statements that are true.

lara [203]

Answer:

Correct answers:

A. An angle that measures $\frac{\pi}{6}$ radians also measures $30^o$

C. An angle that measures $180^o$ also measures $\pi$ radians

Step-by-step explanation:

Recall the formula to transform radians to degrees and vice-versa:

$\angle\,radians=\frac{\pi}{180^o} \,* \,\angle degrees\\ \\\angle\,degrees=\frac{180^o}{\pi} \,* \,\angle radians$

Therefore we can investigate each of the statements, and find that when we have a $\frac{\pi}{6}$ radians angle, then its degree formula becomes:

$\angle\,degrees=\frac{180^o}{\pi} \,* \,\angle radians\\\angle\,degrees=\frac{180^o}{\pi} \,* \,\frac{\pi}{6} \\\angle\,degrees=\frac{180^o}{6} \\\angle\,degrees=30^o$

also when an angle measures $180^o$ , its radian measure is:

$\angle\,radians=\frac{\pi}{180^o} \,* \,\angle degrees\\\angle\,radians=\frac{\pi}{180^o} \,* \,180^o\\\angle\,radians=\pi$

The other relationships are not true as per the conversion formulas

How many solutions does this equation have?

Leto [7]

Answer:

The given equation having only one solution i.e., "w = 3". A further explanation is provided below.

Step-by-step explanation:

The given equation is:

⇒ $9(w-9)-2=-7w+7(w-8)$

By opening the brackets, we get

⇒ $9w-81-2=-7w+7w-56$

⇒ $9w-83=-56$

On adding "83" both sides, we get

⇒ $9w-83+83=-56+83$

⇒ $9w=27$

⇒ $w=\frac{27}{9}$

⇒ $=3$
