Yes a square is a parallelogram.
Answer:
67°
Step-by-step explanation:
A right angle = 90°
90° - 23° = x° = 67°
the parabola has maximum at 9, meaning is a vertical parabola and it opens downwards.
it has a symmetry at x = -5, namely its vertex's x-coordinate is -5.
check the picture below.
so then, we can pretty much tell its vertex is at (-5 , 9), and we also know it passes through (-7, 1)
