5. determine which ordered pair is a solution of y=x+2/5

1 answer:

7 0

Well, I believe one ordered pair that is a solution to the equation would be P(3,1). Since by plugging in the X and y values into the equation the left hand side is equal to the right hand side.

Y = X + 2/5
1 = 3+2/5
1 = 5/5
1 = 1.

⦁ Use both methods to find the distance between the points on the number line.

Answer:

4 and 4

Step-by-step explanation:

Method A

1) Method A: Let 2 be the starting point and -2, the finishing one. Counting between 2 and -2, we can count a distance of 4 units. That's the simplest way, but not convenient to great numbers on the Number Line.

Method B:

There is no such thing as a negative distance, as a physical quantity. So this is the reason why we need to compute the absolute value of two numbers, which is simply what was done on Method B.

|2-(-2)|=|4|=4

As we are dealing with absolute values, the order is not relevant after all, the result remains the same. Take a look:

|-2-2|=|-4|=4

That's why the greater (2) or the lesser number (-2) can be the subtrahend (in bold within the brackets.
