When a ferry boat is on open water, it travels at a constant speed. A ferry boat traveled 4 miles in 10 minutes. Complete the eq

ozzi

Answer:

The equation is: $y=0.4x$

The relationship between the time in minutes, t, and the distance traveled in miles, d is a straight line, as shown in attached graph.

Step-by-step explanation:

As boat travels at constant speed.

So, if ferry boat travels 4 miles in 10 minutes. It means it would complete 24 miles in one hour.

And in 1 minute, 0.4 miles will be completed.

So, the equation becomes

$y=0.4x$

As the slope intercept form is $y=mx+c$

So, $m=0.4$ is the slope

The relationship between the time in minutes, t, and the distance traveled in miles, d is a straight line i.e. linear.

The graph is also attached which indicates that relationship between the time in minutes, t, and the distance traveled in miles, d is a straight line i.e. linear.

Tell whether the system has one solution, infinitely many solutions, or no solution.

nadya68 [22]

X=-7y+34
x+7y=32

To begin with make the two problems the same kind of problem. By adding 7y on both sides for the first problem.
x+7y=34
x+7y=32

So the correct answer would be no solution because it's the same problem and it can't equal to different answers.
