Which graph represents the inequality y > 3 − x ?
viktelen [127]

To solve this problem you must think in this way.

First we see that function y is greater than 3-x, conclusion is the following

shaded area must be above function. That condition is satisfied by the graph 3 and 4.

Then we write inequality in the slope form  y> -x+3.

We see that the coefficient of direction is -1 (negative) which mean that the graph is decreasing. That condition is satisfied by the graph No 4.

The correct answer is graph number 4 ( or D.)

Good luck!!!

What place value do micrometers go too?
BigorU [14]

Answer:

  • <u><em>The place value of micrometers is the millionths.</em></u>

Explanation:

<em>Place value</em> is how much a digit is worth according to the position it has in the number.

In a one digit number, the only digit is in the place of the ones.  That means, that the digit is itself. For instance 8, values 8 × 1, because it is in the place of the ones.

In a two digit numbers, the number to the right is in the place of the ones, and the number to the left is in the place of the tens. Then, the number on the left values 10 times itself. For instance in the number 28, 8 values 8×1 and 2 values 2×10 = 20. That makes 20 + 8 = 28.

From rigth to left the place values are:

  • Ones
  • Tens
  • Hundreds
  • Thousands
  • Ten-thousands
  • Hundred-thousands
  • Millions

For the decimals, you count the place values from left to right. They are:

  • Tenths
  • Hundreths
  • Thousandths
  • Ten-thousanths
  • Hundred-thousanths
  • Millionths

Micrometers is a unit that is one-millionth of a meter:

  • 1 mcirometer = 10⁻⁶ meter
  • 1 micrometer = 0.000001 meter

Hence, the place value of micrometers is the millionths.
