Answer:
90
Step-by-step explanation:
Use the coordinates of the two black dots:
(2,3) and (7,6)
Slope is the change in Y over the change in X:
Slope = (6-3) / (7-2)
Slope = 3/5
Answer:
6.2 x 10^10
Step-by-step explanation:
<h3>
Answer: x = 0</h3>
Work Shown:
y = -3x^2 - 12 is the same as y = -3x^2 + 0x + (-12)
Compare this to y = ax^2 + bx + c, and we'll find that
a = -3
b = 0
c = -12
Plug the 'a' and 'b' values into the formula below and simplify
h = -b/(2a)
h = -0/(2*(-3))
h = 0
The x coordinate of the vertex is x = 0, so the axis of symmetry is also x = 0.
The axis of symmetry lays perfectly on top of the y axis.
