Answer:
Step-by-step explanation:
f(x) = |x - h| + k has a vertex at (h, k), where both h and k are positive. Only
"On a coordinate plane, an absolute value graph has a vertex at (2, 1)" satisfies those requirements.
Answer:

Distance = 21 miles.
Step-by-step explanation:
Let x be the distance in miles between the airport and Ann's home.
We have been given that Ann took a taxi home from the airport. The taxi fare was $2.10 per mile. So fare for x miles will be 2.10x.
We are also told that she gave the driver a tip of $5. Ann paid a total of $49.10. This means that fare of x miles and tip given to driver equals $49.10. We can represent this information in an equation as:

Now let us solve our equation.



Therefore, the equation
represents the distance in miles between the airport and Ann's home and distance between Ann's home and airport in 21 miles.
The expressions is undefined in the set of the real numbers.
Substitute t = 0, to get the initial height
The area of a triangle is 1/2 the base times the height.
The base is 15 and the height is 13.
Area = 1/2 x 15 x 13 = 97.5 sq. units.
The answer is A.
