Answer:

2nd option: 2y=6x+8 and y=3x+4

Step-by-step explanation:

If you divide the first by 2, you get the second equation.

This means that both equations plot an identical line (they lie on top of each other /also known as "coincide"). This means, that there are infinitely many solutions.

In 2D (x-y plane for example), straight lines can have no solutions if they have the same gradient/slope/ they are parallel and different y-intercepts, because they will never cross.

Here, they have same gradient and y-intercept so all points on the line are valid solutions to the equation

Answer:

I'm gonna use the distance formula:

Distance = sqrt((x2-x1)^2 + (y2-y1)^2)

Distance = sqrt((6-3)^2 + (13-9)^2)

Distance = sqrt(3^2 + 4^2)

Distance = sqrt(9 + 16)

Distance = sqrt(25)

Distance = 5

The problem says every unit = 1 mile so 5 units = 5 miles.

Answer = 5 miles

in 4.5 hours, 11.25 inches of snow fell suppose the same amount of snow fell each hour how much snow fell each hour

Julli [10]

If 11.25 inches snow fell in 4.5hrs,
Then for each hr how much snow fell?

So,
4.5 : 11.25
To find how many inches that fell per hour who would need to divide the number of inches by the numbers of hours

11.25 divided by 4.5 = 2.5

So the answer would be 2.5 inch was of snow per hour
