Answer:
y = 2/3x - 1
Step-by-step explanation:
Find the slope:
2y = 3x - 5
2/2y = 3/2x - 5/2
y = 3/2x - 5/2
Slope is 3/2
In order for a line to be perpendicular the slope in the equation should be flipped. 3/2 becomes 2/3.
Perpendicular equation:
y = 2/3x + b
b is going to be equal to the y intercept of the point they gave us, so -1.
Answer: y = 2/3x - 1
Step-by-step explanation:
For solving, use quadratic formula
First, you need to convert 920,000 meters to kilometers because the speed of the train is kilometer per hour, 920,000 meters is equal to 920 kilometers. Then, all you need to do left is take 920 (the distance from Paris to Nice in kilometer) and divide it by 230 (the speed of the train), so you will get 4. So you should write the answer like this: "The total time that took Lola to get from Paris to Nice is 4 hours."
Hope this help you.
