F(x) = -(x2+x-72)
y = -(x - 8)(x + 9)
the solutions are x = 8, -9; so the parabola is upside down (umbrella) crossing the x at 8 and -9, meaning that -9 + 8 = -1/2 = -0.5 is where the focus is, or x = -0.5 as the axis of symmetry
Answer:
precipitation
Step-by-step explanation:
Answer: the slope is 5/4
step by step explanation: -9-6=-15 3- -9=12
15/12= 5/4
