Two trains leave towns 1152km apart at the same time and travel toward each other. one train travels 14km/h slower than the other. if they meet in 4 hours, what is the rate of each train?

137 km/h and 151 km/h

Step-by-step explanation:

Let x km/h be the rate of slower train, then (x+14) km/h is the rate of faster train.

In 4 hours:

Since they meet in 4 hours, then they cover in total the whole distance between two cities, so

4x+4(x+14)=1152

Solve this equation for x:

4x+4x+56-1152

8x=1152-56

8x=1096

x=1096/8

x=137 km/h

x+14=137+14=151 km/h

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
