The graph of function like that may may never cross the x-axis,
so the function could have no real zeros.
If it does have zeros, they will come in pairs,
because "what goes up must come down" and vice versa.
Of course the function cannot have more zeros than its degree.
For example, a polynomial function of degree 6 could have 0, 2, 4, or 6 real zeros.
Answer:
C. 4
Step-by-step explanation:
Because there is always a 50/50 chance of getting the similar result.
Hope this helps.
slope = m=(y2-y1)/(x2-x1)
m= (4-5)/(1-(-2))
m= -1/(1+2)
m=-1/3
Choice C
open the parenthes. and then after that you'll get 27+12x-15. if you simplify that then you'll get 12x+12
Since the distances were the same you can find the average speed directly by adding the speeds then dividing by 2. No need to weight anything.
If we’re considering speed regardless of direction, the average speed is:
(24 + 16) / 2 = 40 / 2 = 20mph
However if direction matters, then one number has to be negative since the directions are opposite:
(24 - 16) / 2 = 8 / 2 = 4mph (in the positive direction)
Depending on the context, either of these could be your answer.
