Answer:
Step-by-step explanation:
1¾ miles/(2⅓ minutes) = (7/4 miles)/(7/3 minutes) = ¾ mile/minute
21 minutes × ¾ mile/minute = 15.75 miles
60 minutes × ¾ mile/minute = 45 miles
All you need to do is substitue -2 into the equation for x,
h(-2) = 3(-2) + 1 = -6 + 1 = -5
700 because the 9 in the tenth place is larger than 5
