ASAP please it’s very important

Answer:

x = 30° and 330°

Step-by-step explanation:

Assuming the intervals is {0 , 2π} or {0° , 360°}

$tan\ x=\frac{-\sqrt{3} }{3} \\\\x=tan^{-1} (\frac{-\sqrt{3} }{3})\\\\x = -30$

So it means it lies in the 2nd and 4th quadrant because tangent is negative in the 2nd and 4th quadrant

so the two solutions are

x = 30° and 330° or

$x=\frac{\pi }{6}\ radians\ \ , \ \ \frac{11\pi }{6}\ radians$

Find the type and number of solution for g(x) = x2 -14x = -50

inysia [295]

Answer:

Step-by-step explanation:

x² -14x+50= 0

this equation has 2 solutions because is a quadratic

the solurions are imaginary roots because the discriminant is less then 0

b²-4ac = (-14)²-4*1*50 = 194-200= -6

to find the actual roots use the quadratic formula

What is the smallest solution to the equation 3x<img src="https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20" id="TexFormula1" title=" x^

topjm [15]

IF you mean $3 x^{2} -16=131$ , then the following would be a solution:

First add 16 to both sides of the equation:
$3 x^{2} = 147$

Now divide both sides of the equation by 3:
$x^{2} =49$

Take the square root of both sides to solve for "X", or simply solve by inspection: "what number(s) can be squared to get 49?"

Answer: -7 and 7 So the smallest solution would be "-7"
