Please Help!!<br><br> Use the graph of the equation to solve: -2x - 5 = 3
abruzzese [7]

Answer:

x = -4

Step-by-step explanation:

-2x - 5 = 3

Add 5 to both sides

-2x - 5 + 5 = 3 + 5

Simplify

-2x = 8

Divide both sides by -2

-2x/-2 = 8/-2

Simplify

x = -4

Why is the product of a rational number and an irrational number Irrational?
Llana [10]

Answer:

Because the product is always non-termination,non-repeating decimal.

Step-by-step explanation:

If we have a is irrational;  b is rational such that b \neq 0 , then a \cdot b is irrational.

A way to represent this is:

a\in\mathbb{R}\setminus\mathbb{Q}, b\in\mathbb{Q},ab\in\mathbb{Q}\implies a\in\mathbb{Q}\implies\text{Contradiction}\therefore ab\not\in\mathbb{Q}.

Note that we have a contradiction, because a is not a rational number, as I stated in the beginning. Therefore, ab is irrational.

How do you find volume of sphere, cylinder, cone ? ... explaining please
boyakko [2]

Answer:

hmmmm

Step-by-step explanation:

Cone

The volume of a cone is linked to the volume of a cylinder. A cone is one third of the volume of a cylinder. The volume of a cone is ¹/₃ × π × r² × l. To calculate the volume we multiply these values together. The answer will be written in units³.

Sphere

The volume of a sphere is ⁴/₃ × π × r³. To calculate the volume we multiply these values together. The answer will be written in units³.

Cylinder

The volume of a cylinder is π × r² × l (r is the radius of the circle and l is the length of the cylinder). To calculate the volume we multiply these values together. The answer will be written in units³. It is more accurate to use π = 3.142 or the π button on a calculator.

   A cone is a 3D shape with 2 faces and one edge

   A sphere is a 3D shape. It has one continuous face and no edges

   A cylinder is a type of prism. It has 3 faces and 2 edges
