Answer:
7.66666666667
Step-by-step explanation:
Answer:
The equation of line can be written as,
y = mx + c
where, m is slope
and c is intercept of line.
Now, Suppose we have equation: ax + by + c = 0
So, transforming the given equation in above standard equation.
⇒ by = -ax - c
⇒
Now comparing this equation with standard equation. We get,
and
Hence, Intercept =
for line ax + by + c = 0.
Let x be the number of hours she jogs, and y be the number of hours she bikes.
The total time would then be x + y = 5
The total distance (based on the given speeds) would be 6x + 12y = 50
Multiply the first equation by 6 to get 6x + 6y = 30
Subtract this from the second equation to get 6y = 20
y = 10/3 or 3 1/3
Substitute this value back into the first equation to get x = 5/3 or 1 2/3
Therefore, Yolanda will have to jog 1 2/3 hours and bike 3 1/3 hours.
