Emma is training for a 10 kilometer race. she wants to beat her last 10 kilometer time, which was 1 hour 10 minutes emma
has already run for 55 minutes. which inequality can be used to find how much longer she can run and still beat her previous
time? (1 hr = 60 min)
70> -55
70 < -55
70 st+55
70 > i+55

Step-by-step explanation:

The last inequality expresses better this situations.

Emma wants to beat her last record, which was 70 minutes. So, she needs to run in less than 70 minutes.

However, she already ran 55 minutes, the remaining time would be the variable I, so, the sum of them must be less than 70 minutes. So, there are two options to represent this:

I + 55 < 70 or 70 > I + 55.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
