The speed that should be taken by Lionel to get to the destination will be 78 miles per hour.
<h3>How to calculate the speed</h3>
From the information given, when Lionel drives from Barcelona to Madrid, 390 miles, it takes him about 6.5 hours.
The speed to make the trip in 5 hours will be:
Speed = Distance / Time
Speed = 390/5
Speed = 78 miles per hour.

Answer:
1. y-25=5/2(x-14)
2. ![y=\frac{5}{2}x-10](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B2%7Dx-10)
3. 5x-2y=20
Step-by-step explanation:
first, find the slope, m.
slope = rise/run = (75-25)/(34-14)= 50/20 = 5/2
1. point slope form: y-25=5/2(x-14)
2. ![y=\frac{5}{2}x-10](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B2%7Dx-10)
3. switch the y to the right side: (5/2)x-y-10=0 --> (5/2)x-y=10
5x-2y=20
Here are the true statements:
The 6 in the third term is a coefficient. It is paired with a variable so it is a coefficient.
The y in the third term is a factor because it is being multiplied by (6x + 7).
The 9 is a constant because it is just a number in the second term.
