4b - 3 > -1
+3 +3 ⇒ 4b > 3-1 ⇒ 4b > 2 ⇒ b > 2/4 ⇒ b > 1/2 :)))
i hope this be helpful
* happy new year *
Answer:
The equality is false because one side is positive and the other side negative.
Step-by-step explanation:
5(4)+7
Multiply the numbers 4 and 5
20
20+7
add the numbers 20 and 7
27
-3
so the number 4 is not the solution
Using <u>distance between two points</u>, it is found that the total distance covered on the tour is of 3400 miles.
Given two points
and
, their distance is given by:
![D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}](https://tex.z-dn.net/?f=D%20%3D%20%5Csqrt%7B%28x_2%20-%20x_1%29%5E2%20%2B%20%28y_2%20-%20y_1%29%5E2%7D)
In this problem, the formula is used to find the distance covered on each tour, hence:
![d_{AB} = \sqrt{(400 - 0)^2 + (300 - 0)^2} = 500](https://tex.z-dn.net/?f=d_%7BAB%7D%20%3D%20%5Csqrt%7B%28400%20-%200%29%5E2%20%2B%20%28300%20-%200%29%5E2%7D%20%3D%20500)
![d_{BC} = \sqrt{(-800 - 400)^2 + (800 - 300)^2} = 1300](https://tex.z-dn.net/?f=d_%7BBC%7D%20%3D%20%5Csqrt%7B%28-800%20-%20400%29%5E2%20%2B%20%28800%20-%20300%29%5E2%7D%20%3D%201300)
![d_{CD} = \sqrt{(-800 - (-800))^2 + (0 - 800)^2} = 800](https://tex.z-dn.net/?f=d_%7BCD%7D%20%3D%20%5Csqrt%7B%28-800%20-%20%28-800%29%29%5E2%20%2B%20%280%20-%20800%29%5E2%7D%20%3D%20800)
![d_{DA} = \sqrt{(0 - (-800))^2 + (0 - 0)^2} = 800](https://tex.z-dn.net/?f=d_%7BDA%7D%20%3D%20%5Csqrt%7B%280%20-%20%28-800%29%29%5E2%20%2B%20%280%20-%200%29%5E2%7D%20%3D%20800)
Then, the total <em>distance </em>is given by the sum of each separate distance, hence:
![d = d_{AB} + d_{BC} + d_{CD} + d_{DA} = 500 + 1300 + 800 + 800 = 3400](https://tex.z-dn.net/?f=d%20%3D%20d_%7BAB%7D%20%2B%20d_%7BBC%7D%20%2B%20d_%7BCD%7D%20%2B%20d_%7BDA%7D%20%3D%20500%20%2B%201300%20%2B%20800%20%2B%20800%20%3D%203400)
The total distance covered on the tour is of 3400 miles.
