Answer:
y = -1/4x^2 -3/2x +3/4
Step-by-step explanation:
You know that vertex form is ...
y = (1/(4p))(x -h)^2 +k
for a focus-vertex distance of p and a vertex of (h, k).
Here, the focus-vertex distance is 2-3 = -1 (difference of y-coordinates), and the vertex is (h, k) = (-3, 3). This means the vertex form equation is ...
y = -1/4(x +3)^2 +3
Expanding the square gives ...
y = -1/4(x^2 +6x +9) +3
y = -1/4x^2 -3/2x +3/4

The square of a binomial is ...
(x +a)^2 = x^2 +2ax +a^2
Answer:-6
Step-by-step explanation:
4n+16-3n=10, n+16=10, thus, n=10-16, which is -6

Answer:
x = 111
Step-by-step explanation:
126+158+120+125+121+139 = 789
900-789 = 111
(n-2)*180
5*180 = 900
Negative rate of change just means the graph is falling. This one is falling everywhere after x=0.5. The only choice in that section of the graph is the last one.
