Answer:
To know what is the average of it
Step-by-step explanation:
Answer x=-4
This would make a straight line going perpendicular to y=-3 and would pass through the point -4,3.
Vertex: (1,-4)
axis of symmetry: x=1
min
minimum value: y=-4
x intercepts: -1, 3
y intercept: -3
i dont know how to find solutions or roots sorry
each letter can be 1 of 26 letters
each number can be 1 of 10 digits
so you get
26 * 26 *26 * 10 *10 = 1,757,600 combinations
