Rounding number can be very easy to work with in the head. The rounded number is the approximate value.To round a number to the nearest thousand simply means making the last three digit into the next lower number that ends in 000. Example round 6897 to the nearest thousand . The last three digits 897 depict that 6897 is more closer to 7000 than 6000 so, the nearest thousand of that value (6897) will be 7000.
The number can be either rounded up or down to the closest thousand depending on the closest to the nearest thousand. 6347 tot the closest thousand will be 6000 . Notice that the last three digits(347) indicate that the number (6347) is more closer to 6000 than 7000.
From the example above the three numbers that can be rounded to 38 000 are
We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0 y^2-3y=0 y(y-3)=0 y1=0 -----------y2=3
