Estimate the difference 68,283−47,849 by rounding each number to the nearest ten thousand.

70,000-50,000=20,000

Step-by-step explanation:

Step-by-step explanation:

Given that,

68,283−47,849

The difference is just

20,434

Note when we say nearest ten thousand, we meant 10,000, so there should be a minimum of four zeros

So,

20,434 = 20,000

Since the last number converted is not up to 5, we will not add 1 to 2.

So the answer is 20,000

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)
