I don't know where you got those answers, but the actual equation that represents those points is: y = -1/2x + 11. None of those listed above are correct.
It is true because a rational function is defined as those functions where the variable is placed in the denominator, which must be restricted, because all denominators cannot be equal to zero, other wise it would be undetermined
Answer:
The second and fourth one
Step-by-step explanation:
The open circle means more/less than or equal to and the closed circle is only more than or less than and it is greater so it goes right
Answer:
Step-by-step explanation:
S = second; F = flying time.
Since it can flap its wings 30 times, each second, we have already found our answer. The relationship between flying time (Wing flaps) and seconds is 30. In other words, it beats it's wings 30 times each second. Which is what the question asks.
Now we just have to write the equation:
This is because the seconds are <u>dependent</u> on the flap of wings, so s would be the y value.
Hope it Helps!
I belive it c but i mit be wrong so dont mark it
