Explanation

To solve this equation, we can set up a proportion:

x/y = y/1

To solve for x, we can cross-multiply:

x = y * y / 1

Simplifying this expression, we have:

x = y^2

Explanation

The Backstage view was introduced in Word 2010. 

This acts as the central place for managing your documents.

The backstage view helps in:

• creating new documents
• saving and opening documents

Explanation

Active: "A nice present was given to Sue by Esther."

Passive: Sue was given a nice present by Esther.

In this sentence, the subject ("Esther") becomes the object in the passive sentence,

and the direct object ("a nice present") becomes the subject in the passive sentence.

The verb "gave" changes to "was given" in the passive voice,

Active and the preposition "to" is used to indicate the recipient of the action ("Sue").

Explanation

Given the equation x - 1 = 0,

we can solve for x by isolating it on one side of the equation.

1. Equation:

x - 1 = 0

2. Adding 1 to both sides:

x - 1 + 1 = 0 + 1

3. Simplifying:

x = 1

Explanation

1. Center:

To check for symmetry, we first need to identify the center of the graph.

The equation is in the form of a circle, x^2 + y^2 = 1, which has its center at the origin (0,0).

2. x-axis symmetry:

A graph is symmetric about the x-axis if replacing y with -y in the equation does not change the equation.

Let's test this:

x^2 + (-y)^2 - x = 1

x^2 + y^2 - x = 1

As we can see, the equation remains the same, so the graph is symmetric about the x-axis.
