Answer:
(1) x= −1 /2 y+ 5 /2
(2) x= −1 /2 y−2
Step-by-step explanation:
(1) 2x+y=5
Step 1: Add -y to both sides.
2x+y+−y=5+−y
2x=−y+5
Step 2: Divide both sides by 2.
2x /2 = (−y+5)/2
x= −1 /2 y+ 5 /2
(2) Step 1: Flip the equation.
−2x−4=y
Step 2: Add 4 to both sides.
−2x−4+4=y+4
−2x=y+4
Step 3: Divide both sides by -2.
−2x /−2 = (y+4) /−2
x= −1 /2 y−2
A train is traveling at a constant speed and goes a distance of 7 1/2 kilometers in 6 minutes the train will continue at this speed the train will travel a distance of d kilometers in m minutes write an equation that represents the relationship between d and m
Answer:
392939939393939399393939393
Step-by-step explanation:
An equation that represents the relationship between d and m can be written as d = 1.25 m.
What is Speed?Speed of an object is the rate of change of position of an object in any direction.
Speed is a scalar quantity because it does not have any direction, it only has magnitude. Speed with direction is called velocity.
The formula for calculating speed is,
Speed = Distance / Time
Given distance the train travelled = 7 [tex]\frac{1}{2}[/tex] kilometers
= 15/2 kilometers
= 7.5 kilometers
Time taken to travel the distance = 6 minutes
Speed = 7.5 / 6
= 1.25 kilometers / minute
Given that speed of the train is constant.
Hence for any distance 'd' kilometers in 'm' minutes,
d / m = 1.25
d = 1.25m
Hence d and m can be related by the equation d = 1.25m.

5
OD. The data represent a linear function because there is a common
difference of -9.
Answer:
The common difference is same = d = -9
Therefore, the data represent a linear function.
Step-by-step explanation:
Given the table
x y
1 4
2 -5
3 -14
4 -23
5 -32
Finding the common difference between all the adjacent terms of y-values
d = -5 - 4 = -6,
d = -14 - (-5) = -14+5 = -9
d = -23 - (-14) = -23 + 14 = -9
d = -32 - (-23) = -32 + 23 = -9
It is clear that the common difference between all the adjacent terms is same.
Thus,
d = -9
We know that when y varies directly with x, the function is a linear function.
Here, it is clear that each x value varies 1 unit, and each y value varies -9 units.
i.e. The common difference is same = d = -9
Therefore, the data represent a linear function.
