Answer:
Neither, they have a solution
Step-by-step explanation:
Use a sheet of graphing paper and graph the equation using the y-intercept and slope.
Literally plugging in the time for each value, we can plug in 5 for t to get
22000+(-480*5)=22000+(-2400)=22000-2400=19800
Plugging in 10, we get 22000+(-480*10)=22000-4800=17200. We can turn 22000+(-480*10) into 22000-(480*10) using the distributive property, and adding a negative number to something essentially means to subtract that number.
I challenge you to do t=15 and 20 on your own!
So I'm guessing that the x2 is your way of saying 2 is the exponent right? In that case the equation would be 8x^2 + 12x
Well you would have to pull out the gcf which in this case will be 4x after pulling out the gcf you should get 4x(2x + 3)
2400/700 gives you about 3.42ft for each person.
