No, because it says bridge B has twice as many so there are 40 cars for 2 hours because it says twice as much time. So the unit rate is 20 cars each hour, so there will be the same unit rate.

Can anyone please find the domain of this function
mihalych1998 [28]

Answer: [-1/8, infinity) , {x | X greater than or equal to -1/8}

Step-by-step explanation:

Domain is what x can be. Thus, in the function f(x), we place limits such as x cannot make the square root a negative number because then it would not be a real number. Thus 8x+4-3 can be simplified to 8x+1. Setting this to 0, we get 8x+1=0 which solves out to x cannot equal -1/8. Thus, x can equal and be greater than -1/8.
