What is the distance between the points (2, 5) and (5,9)?

The graph for the system of inequalities without the shading of its solution set is shown on the coordinate grid.

BartSMP [9]

Answer:

C. Area 3

Step-by-step explanation:

<h3>The first line</h3>

Line x - y > 5 ⇒ y < x - 5

<u>This line has positive slope and the y-intercept is -5, shaded area is below the line, covers the areas:</u>

Area 3 and Area 4

<h3>The second line</h3>

Line x + 2y < -6 ⇒ 2y < - x - 6 ⇒ y < -1/2x - 3

<u>This line has negative slope and the y-intercept is -3, shaded are is below the line, covers the areas:</u>

Area 2 and Area 3

<u>Solution of the system is the intersection of the areas:</u>

Area 3

Select the correct answer. Consider these three numbers written in scientific notation: 6. 5 × 103, 5. 5 × 105, and 1. 1 × 103.

Karo-lina-s [1.5K]

Scientific notation uses expression which gives easy access of order. The greatest number is $5.5 \times 10^5$ .It is greater by smallest number by 500 times.

<h3>How to convert a number to scientific notation?</h3>

It is usually of the form $a.bc.. \times 10^k$ exponent of 10 starts)

(we have 1 ≤ |a| < 10 ) (where |a| is magnitude of a without sign)

This notation is used to get some idea of how large or small a number is in terms of power of 10.

<h3>What are some basic properties of exponentiation?</h3>

If we have $a^b$ base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
