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

20,000

Step-by-step explanation:

ten thousands, thousands, hundreds, tens ones

We need to round each number to the nearest ten thousands

68,283

We look at the thousands term and if it is 5 or higher we round up

8 is five or higher so we round up

70,000

47,849

We look at the thousands term and if it is 5 or higher we round up

7 is five or higher so we round up

50,000

70.000-50,000=20,000

the answer is simply just 6n add the two together as they have an n

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
