I think the answer is ;B.316 and 38
Answer:
I think it is 1/25k if not im sorry
Answer:
Yes, if you keep all of this in mind... This all came from my lesson during class btw.
Step-by-step explanation:
Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. If the graphs of the equations do not intersect. Almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit. Many people use linear equations every day, even if they do the calculations in their head without drawing a line graph. When both equations have the same slope, but not the same y-intercept, they'll be parallel to each other and no intersections means no solutions. When both equations have different slopes than regardless of the y-intercept they'll intersect for certain, therefore it has exactly one solution. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
Answer:
m = 1.25d
Step-by-step explanation:
A train is traveling at a constant speed and goes a distance of 7 ½ kilometers or 7.5 km in 6 minutes.
6 min = 7.5 km
1 min = (7.5/6) km/min
= 1.25 km/min
or
In m min, (7.5/6)d is travelled by the train. Hence, the relation between d and is :
Hence, this is the required solution.
