The graph for the inequality given is graph 1.

What is an inequality?

An inequality is a relation between two numbers or expressions that are not equal. It can show which of them is greater or smaller by using symbols like < or >. It can also be a statement of fact about the order relationship of quantities.

Given that an inequality, 2-(x+3) < 4 -2x, we need to determine its graph,

For the same solving the inequality,

2-(x+3) < 4 -2x

2-x-3 < 4 - 2x

Add x to both sides,

2-3 < 4-x

-1 < 4-x

Subtract 4

-1-4 > -x

x > 5

Since, the x is greater than 5 so the graph will be the numbers that greater than 5,

Hence, the graph is 1.

Why is it important to know how to use area or volume in real life?

Answers

It’s important because you may doing something that includes that and you don’t have a ruler etc..
The concepts of area and volume all talk about how much space a 2D or 3D figure occupies. In real life, there are certain jobs that include measuring and geometry, which you will be able to accomplish by your math skills. For example, engineering involves analyzing and modeling certain objects. Even if work is not included, the daily activities we do, sometimes include area and volume. Such as finding a gift box where your gift perfectly fits and measuring your daily water intake.

Answers

Answer:

Equation for the skating palace

= 6 + 2x

Step-by-step explanation:

For skating palace, the equation is written as:

The slating palace charges a $6.00 shoe rental fee plus $2.00 an hour to skate.

$6 + $2 × x

= 6 + 2x

For Mathland , the equation is written as:

Mathland skating rink charges $4.00 an hour to skate .

$4 × x

Answers

Answer:

b = 30°

Step-by-step explanation:

a + b + 90° = 180°

60° + 90° + b = 180°

150° + b = 180° ( subtract 150° from both sides )

b = 30°

B is 30 degrees not 120

Elena thinks length BC is 16.5 units. Lin thinks the length of BC is 17.1 units. Do you agree with either of them? Explain or show your reasoning.


​

Answers

Answer:

Option D, I agree with neither Elena nor Lin

Step-by-step explanation:

The remaining part of the question is attached herewith

Solution

As we can see in the image  

ED is perpendicular to AB and BC is perpendicular to AB

Thus, as per the Pythagoras theorem,  

AC^2 = AB^2 + BC^2  

14^2 = 6^2 + BC^2

BC^2 = 196-36 = 160

BC = 12.649 OR 12.65

Hence, option D
