Find the domain of the rational function. Write using interval notation. f(x) =
4x-1
10 + 5x

the answer will be the last one

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

once you solve it out the value of x is 13
