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:

$x+3\ge 2$

Solving inequality

$x+3\ge 2$

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:

Given:

{(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 comparison and contrast between a square and an equilateral triangle are stated and explained below:

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

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

Comparison: i. The two shapes have equal lengths of sides.

ii. An equilateral triangle and a square are examples of plane shapes.

Contrast: i. An equilateral triangle has three sides, while a square has four sides.

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

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