therefore, the actual distance is 280 miles.
(sorry, idk the rule for it)
Answer:
7.(1,0) and (-4,0)
8. (-3,0) and (-2,0)
Step-by-step explanation:
7.
When the function is equal to zero, we are looking for the zeros, or the x intercepts
Where it crosses the x axis are 1 and -4
(1,0) and (-4,0)
8. When the function is equal to zero, we are looking for the zeros, or the x intercepts
Where it crosses the x axis are -3 and -2
(-3,0) and (-2,0)
Answer:
-13
Step-by-step explanation:
Given that:
Average temperature for a period of 4 days = - 8
Average temperature for a 5 day period = - 9
Temperature on the 5th day:
(total temp for the 4 days + 5th day temperature) / 5 = - 9
Let 5th day temperature = x
Total temperature for the 4 days = 4 * - 8 = - 32
(-32 + x) / 5 = - 9
-32 + x = - 45
x = - 45 + 32
x = - 13
