Answer:
y = -5x - 23
Step-by-step explanation:
Point-slope form:
y - 7 = -5(x + 6)
rearrange:
y - 7 = -5x - 30
y = -5x - 23
Answer:
(-1,-1)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2
(1+-3)/2 = -2/2 = -1
To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2
(-6+4)/2 = -2/2 = -1
(-1,-1)
The relative speed of the car to the truck while moving towards each other is the sum of the speed of both vehicles.
- The time it takes them to meet is <u>1 hour</u>
Reasons:
The distance between the cities, d = 145 miles
The time it takes a truck to cover the distance = 2.5 hours
The speed of the car = 1.5 × Th speed of the truck
Required:
The time it takes them to meet if they are moving towards each other.
Solution:

Therefore;
The speed of the car,
= 1.5 × 58 mph = 87 mph
At the time<em>, t</em>, the truck and the car meet, we have;

Which gives;
87 × t + 58 × t = 145

- The time it takes them to meet, <em>t</em> = <u>1 hour</u>
