The total angel of any polygons is (n as the totap side of the polygon)
(n - 2) x 180°

now we can substitute 120° into this formula
(n - 2) x 180° / n = 120° (because we're calculating each angle from the polygon, so we need to divide the equation by n)
(180n - 360) = 120n
180n - 120n = 360
60n = 360
n = 6

Which is the vertex of x2 + 10x = -17 <br><br> (-5,-8)<br><br> (5,8)<br><br> (-5,8)<br><br> (5,-8)
ad-work [718]

Answer:

vertex = (- 5, - 8)

Step-by-step explanation:

Given a quadratic in standard form : ax² + bx + c = 0 : a ≠ 0

Then the x- coordinate of the vertex is

x_{vertex} = - \frac{b}{2a}

Given x² + 10x = - 17 ( add 17 to both sides )

x² + 10x + 17 = 0 ← in standard form

with a = 1, b = 10, c = 17, then

x_{vertex} = - \frac{10}{2} = - 5

Substitute x = - 5 into the quadratic for the corresponding value of y

y = (- 5)² + 10(- 5) + 17 = 25 - 50 + 17 = - 8

Hence vertex = (- 5, - 8)

If g(x)= -(3/(4x)) , find g(g(x)) please show work.
ivann1987 [24]

Answer:

g(g(x)) = x

Step-by-step explanation:

g(x) = -\dfrac{3}{4x}

g(g(x)) = -\dfrac{3}{4g(x)}

g(g(x)) = -\dfrac{3}{4(-\frac{3}{4x})}

g(g(x)) = -\dfrac{3}{4} \div (-\frac{3}{4x})

g(g(x)) = -\dfrac{3}{4} \times (-\frac{4x}{3})

g(g(x)) = \dfrac{3 \times 4x}{4 \times 3}

g(g(x)) = x
