Find the image of (-4,-9) after
a rotation of 180° about the origin.

(4, 9)

Step-by-step explanation:

Based on the information I'm given, 180° is 1/2 of 360°

If you drew a graph of (-4, -9) and folded it across into a triangle shape the coordinates would be (4, 9)

I hope this helped!

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
