So,

A denominator is rationalized when there are no irrational or imaginary numbers in it.  Since the square root of 2 is irrational, we just need to multiply the fraction by the square root of 2 over the square root of 2.

\frac{10}{ \sqrt{2} }

Multiply the fraction by the square root of 2 over the square root of 2.
\frac{10\sqrt{2}}{ \sqrt{2}*\sqrt{2} }

Simplify.
\frac{10\sqrt{2}}{2}

5\sqrt{2}

The denominator is now 1, which is a rational number.

Answer:

Step-by-step explanation:

The diagram shows lines passing through the points of two equations.

We will determine the points through which the lines pass through on the graphs.

Looking at the line on the right hand side of the graph, the slope is

(y2-y1)/x(2-x1) where

y2= 0, y1 = 4

x2 = 3, x1=0

Slope, m = (0-4)/3-0

Slope = -4/3

Recall the equation of a straight line is y = mx + c

Where c is the intercept.

So the equation is y

y = -4x/3 + 4

Looking at the line on the left hand side of the graph, the slope is

(y2-y1)/x(2-x1) where

y2= 0, y1 = 2

x2 = -1, x1 =0

Slope, m = (0-2)/-1-0

Slope = -2/-1 = 2

Applying equation of a straight line is y = mx + c

The equation

y = 2x + 2

So the equations are

-4x/3 + 4. If x lesser than or equal 0

2x + 2. If x greater than 0

Which of the following equations represents the line with a slope of 2/3 and a y-intercept of 9?
Alex787 [66]
The last one, the format for equations like these would be y=mx+b where m is the slope and b is the y-intercept, and x and y are variables.

The quotient of two numbers is negative. It must be true that? A. Neither number is negative. B. One of the numbers is negative
denpristay [2]

n mathematics, a negative number is a real number that is less than zero. Negative numbers represent opposites. If positive represents movement to the right, negative represents movement to the left. If positive represents above sea level, then negative represents below level. If positive represents a deposit, negative represents a withdrawal. They are often used to represent the magnitude of a loss or deficiency. A debt that is owed may be thought of as a negative asset, a decrease in some quantity may be thought of as a negative increase. If a quantity may have either of two opposite senses, then one may choose to distinguish between those senses—perhaps arbitrarily—as positive and negative. In the medical context of fighting a tumor, an expansion could be thought of as a negative shrinkage. Negative numbers are used to describe values on a scale that goes below zero, such as the Celsius and Fahrenheit scales for temperature. The laws of arithmetic for negative numbers ensure that the common sense idea of an opposite is reflected in arithmetic. For example, − − 3 = 3 because the opposite of an opposite is the original thing.
