I believe that B) m<3 would need to double. Since m<6 and m<3 are corresponding angles, they are always equal. So if 6 doubles, 3 needs to as well in order to be equal.

Solve the quadratic. x^2+8x+3=0
Reil [10]
Factor
find wht 2 numbers add to 8 and multiply to 3
none do

use quadratic formula which can be used when
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^{2}}-4ac }{2a}

a=1
b=8
c=3

x=\frac{-8+/- \sqrt{8^{2}-4(1)(3)} }{2(1)}
x=\frac{ -8+/- \sqrt{64-12} }{2}
x=\frac{ -8+/- \sqrt{52} }{2}
x=\frac{ -8+/- 2 \sqrt{13} }{2}
x=-4+/- \sqrt{13}

x=-4+ \sqrt{13} or x=-4- \sqrt{13}
aprox x=-7.60555 or x=-0.394449

The quadratic function below has an axis of symmetry through x = -4; a vertex at (-4, -9) and zeroes at x = -7 and x = 0.
Pavlova-9 [17]

Answer:

True

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (- 4, - 9), thus

y = a(x + 4)² - 9

To find a substitute the coordinates of the zero (- 7, 0) into the equation.

0 = a(- 7 + 4)² - 9, that is

0 = 9a - 9 ( add 9 to both sides )

9a = 9 ( divide both sides by 9 )

a = 1, thus

y = (x + 4)² - 9 ← expand factor using FOIL

y = x² + 8x + 16 - 9

y = x² + 8x + 7
