Which graph represents the solution to the inequality x+3 greater than or equal to 2?
Shalnov [3]

Answer:

x+3\ge 2=\begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:\:-1\:\\ \:\:\mathrm{Interval\:Notation:}&\:[-1,\:\infty \:\:)\end{bmatrix}

Please check the attached graph.

Step-by-step explanation:

We know that 'greater than or equal' is represented as '≥'.

Thus, inequality ''x+3 greater than or equal to 2'' is represented as:

x+3\ge 2

<u><em>Solving inequality</em></u>

x+3\ge 2

subtract 3 from both sides

x+3-3\ge \:2-3

simplify

x\ge \:-1

Thus,

x+3\ge 2=\begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:\:-1\:\\ \:\:\mathrm{Interval\:Notation:}&\:[-1,\:\infty \:\:)\end{bmatrix}

Please check the attached graph.

Determine whether the following relation represents a function. Give the domain and range for the relation. StartSet (7 comma 2
weqwewe [10]

Answer:

  • is a function
  • domain: {-4. 3. 5. 7}
  • range: {-4, 2, 3}

Step-by-step explanation:

<u>Given</u>:

  {(7, 2), (5, -4), (3, 3), (-4, -4)}

__

The domain is the set of first numbers:

  {7, 5, 3, -4} . . . domain

The range is the set of second numbers:

  {2, -4, 3} . . . range

No domain values are repeated, so this relation is a function.

Compare and Contrast a square and an equilateral triangle? Be sure to communicate and discuss using mathematical language, ideas
ella [17]

The <u>comparison</u> and <u>contrast</u> between a square and an <em>equilateral triangle</em> are stated and explained below:

What is a <u>square</u>? A <u>square</u> is a <em>plane shape</em> with an equal length of sides. This implies that the <em>measure</em> of its length is the same as that of its <u>breadth</u>.

What is an equilateral triangle? A <em>triangle</em> is a <em>plane shape</em> with<u> three </u>sides, and a <em>sum </em>of its <u>internal</u> angles to equal 180^{o}. Thus an <em>equilateral triangle </em>is a type of triangle with <em>equal lengths of sides</em>, and therefore equal internal angles.

<u>Comparison</u>: i. The two shapes have <em>equal lengths</em> of sides.

ii. An equilateral triangle and a square are examples of <u>plane shapes</u>.

<u>Contrast</u>: i. An equilateral triangle has<em> three sides</em>, while a square has <em>four sides</em>.

ii. An equilateral triangle has <em>three internal angles</em>, while a square has <em>four internal angles</em> which are right angles.

iii. The sum of <u>internal </u>angles of an equilateral triangle is 180^{o}, while that of a square is 360^{o}.
