Round 8923 to the thousands

Answers

Answer:

9000  

Step-by-step explanation:

To  round a number to the nearest thousand, you look at the number in the hundreds place.

If the number in the hundreds place is

  • greater than 5, you add 1 to the number in the thousands place
  • less than 5, you keep the number in the thousands place
  • exactly 5 with only zeros following it, you round the number in the thousands place to the nearest even number

Here's how to round 8923 to the nearest thousand.

  1. The digit in the thousands place is the 8.
  2. The number in the hundreds place (8) is greater than 5.
  3. Add 1 to the digit in the thousands place.

The rounded number is 9000.

Answer:

9000

Step-by-step explanation:

When you are rounding to the thousands, if the hundreds place is 500 or greater you have to round up in the thousands place.

That would mean 8923 rounded to the thousands place would equal 9000

Which description of the graph of the linear inequality y ≥ 7x – 4 is correct? The graph will be a dashed line with a y-intercept of negative four and a slope of seven. The graph will be shaded below the line. The graph will be a solid line with a y-intercept of negative four and a slope of seven. The graph will be shaded above the line. The graph will be a solid line with a y-intercept of seven and a slope of negative four. The graph will be shaded below the line. The graph will be a dashed line with a y-intercept of seven and a slope of negative four. The graph will be shaded above the line.

Answers

      Correct description of the given inequality will be, A solid line with y-intercept (-4) and slope 7. The graph will be shaded above the line.

 Slope form of the line is given by equation,

y = mx + b

Where 'm' = Slope of the line

b = y-intercept

For a line having equation,

y = 7x - 4

Slope = 7

y-intercept = -4

If the line is an inequality, properties of the inequality will be defined by,

  • If the line is having a sign equal to (=), graph of the line will be a solid line.
  • If the solid line has a sign of greater than (>), solution set (shaded region) of the inequality will be above the line.
  • If the line has a sign of less than (<), solution set of the inequality will be below the line.

By these properties,

inequality y ≥ 7x - 4 will show,

  • A solid line with slope 7 and y-intercept as (-4).
  • Shaded area will be above the solid line.

  Therefore, the graph will be a solid line with y-intercept (-4) and slope 7. The graph will be shaded above the line.

Answer:

The correct option is B

B) The graph will be a solid line with a y-intercept of negative four and a slope of seven. The graph will be shaded above the line.

Step-by-step explanation:

The given equation is

y ≥ 7x - 4

Consider only the equality sign:

y = 7x-4

or

y = 7x + (-4)

The general form of any linear equation is given by:

y = mx + c

By comparing, we can see that:

m = slope = 7

Secondly consider the equation

y ≥ 7x - 4

We know that generally for the signs "equal to and greater/smaller than", we use a solid line, and for the signs "greater/smaller than", we use a dashed line.

Hence, to graph this equation we'll use a solid line.

Thirdly, find y intercept by putting x=0

y = 7(0) - 4

y = -4

The correct option is B
