Answer:
53.2 mph
Step-by-step explanation:
Mara's family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m.
1:40 p.m. is 13:40.
Thus, they traveled for
13 hours 40 minutes - 9 hours 10 minutes = 4 hours 30 minutes
that is
hours.
Use formula:

where
D = distance
r = rate
t = time.
In your case,
D = 239.4 miles
t = 4.5 hours
Hence,

Answer:
D
Step-by-step explanation:
A <u>linear inequality</u> is an inequality which involves a linear function. A linear inequality contains one of the symbols of inequality: <, >, ≤, ≥.
Consider all options:
A. The inequality
is not linear linear inequality, because x is in the left part denominator and in the right part numerator.
B. This option shows linear equation, not inequality.
C. This option shows quadratic equation, not linear inequality.
D. This option shows linear inequality 
That any number plus 0 is equal to the number itself.
Answer: Assuming that it's already in the standard form - y=mx+b | Your Y-Intercept is going to be -9
Step-by-step explanation:
Using the equation y=mx+b, anything that is in place of the (b) is your Y-Intercept and your slope is (m)
