Answer:
Y=-x+3
Step-by-step explanation:
First move the the x term to one side. Isolate the y term. Then because the coefficient is 4 in the y term divide the whole equation by 4. Then you get your answer.
The function that describes the distance from the finish line after x minutes is: y = 2/3x + 4
Given : A student is running a 10-kilometer race. He runs 1 kilometer every 4 minutes.
To find : Select the function that describes his distance from the finish line after x minutes = ?
Let the equation of line describing function is y = mx+c ....1
Where, y represents the distance in kilometer and x represents the time in minutes.
A student is running a 10-kilometer race,
⇒ y(0) = b = 10 km
It is also given that he runs 1 kilometer every 4 minutes.
Each passing minute the student is getting closer and closer to the finish line which was 10 kilometers away when the race started.
The distance between the student and the finish line will decrease.
m = 10/4 - 1
m = 2/3
substitute in 1.
y = 2/3x + 4
Therefore, the function that describes his distance from the finish line is
y = 2/3x + 4

Answer:
x = 3
Step-by-step explanation:
Simply solve for x.
In this equation all we have to do is add 6 to both sides of the equation to solve for x.
x = 3
The answer is 3.
