Because for it to be a function each x value can only have one y value. And in the chart it says x is 2 and 8
Answer: k=9/4
Step-by-step explanation: We can do this by finding a number that adds up to 3 when multiplied by 2. The best way to do this is to use ((b^2)/4) which can usually find you the number for a perfect square based on b, which we have. So, 3^2 / 4 =9/4, meaning k=9/4. We can check:
>x^2 +3x +9/4
> (x+3/2)(x+3/2)
Perfect square.
1.60 mi +1.75 mi = 3.35 mi = 3 7/20 mi
Divide both sides by 5 to get t by itself, then you have your answer
The answer is C. (x+6)(x+8)
