Ms. Agokeng is making a trip to Pennsylvania that is more than 250 miles. She has already driven 45 miles and is continuing her drive at 70 miles per hour. Which of the following inequalities represents the amount of time she has left in the car?

The correct answer is A.) 45 + 70x < 250.

y = mx + b

She started at 45 miles (+ 45).

She has to go at least 250 miles (< 250).

She is driving at a constant, unchanging speed of 70 mph (70x).

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
