Answer:
The time at which the two trains will meet is 1 hour and 24 minutes
Step-by-step explanation:
The distances between the two trains = 196 miles
The direction of the two trains = Towards each other
The speed of one of the trains = 80 miles per hour
The speed of the other train = 60 miles per hour
Let 't' represent the time at which the two trains meet, we have;
80·t + 60·t = 196
∴ 140·t = 196
t = 196/140 = 7/5
The time at which the two trains will meet, t = 7/5 hours = 1.4 hours = 1 hour, 24 minutes.
C(1;2)
a = 1
b = 2
r = 4
(x-a)² + (y-b)² = r²
(x-1)² + (y-2)² = 4²
(x-1)² + (y-2)² = 16
Answer:
Step-by-step explanation:
The standard form of a linear equation is 
, where 
, 
, and 
are constants in the equation.
Based on the equation you have provided, the standard form would be 
, where 
.
To find the y-intercept, set 
.
Therefore, the y-intercept is 
.
Do the same thing for the x-intercept, but this time with 
.
Therefore, the x-intercept is 
.
Answer:
