Answer:12
Step-by-step explanation:
Add all the number, and then divide it by number of numbers.
for example, 1, 2, 3, 7, 10
(1+2+3+7+10)/5
23/5 = 4.6 The average is 4.6
Answer: (6,-20)
Explanation:
The equation f(x) = -(x-6)^2 - 20 is the same as y = -1(x-6)^2 + (-20)
It is in the form y = a(x-h)^2 + k
The vertex is (h,k)
In this case, h = 6 and k = -20
So that's why the vertex is (6,-20)
Yes I have graphed them and they form a 90 degree angle
Answer:
A -4 ≤ x ≤ -2
Step-by-step explanation:
The graph is constant where there is a flat, horizontal line. The graph is flat in the interval -4 ≤ x ≤ -2. This is where the graph will be constant. In all of the other parts of the graph, the y-values are changing. Since the line is flat, the y-value doesn't change.
