Which number line represents the solution |2x|-12 =

Mathematics
1 answer:
Bond [772]3 years ago
3 0

Answer:

Third option, last one

Step-by-step explanation:

Let's solve for x first.

|2x| - 12 = -2

|2x| = 10

2x = 10 or -2x = 10

x = 5 or x = -5

The number line that represents this is the last one.

The height and base dimensions of a pyramid are shown in the diagram.
marusya05 [52]

Volume of the pyramid = 40 cubic units

Solution:

Let us find the volume of the pyramid.

Area of the base = \frac{1}{2}\ bh

                            $=\frac{1}{2}\times4\times5

                            = 10 square units

Area of the base (B) = 20 square units

Height of the pyramid = 12

Volume of the pyramid = \frac{1}{3}\times \text{Base}\times \text{Height}

                                       $=\frac{1}{3}\times 10\times12

                                       = 40 cubic units

Volume of the pyramid = 40 cubic units

Can you ever use a calculator to determine if a number is rational or irrational?
timofeeve [1]
A rational number is simply a term that can be expressed as a fraction. Otherwise, that is an irrational number. So, you can use a calculator to verify if the number is rational or not.

The key characteristic of an irrational number is when it contains a long line of decimal places. For example, the term π and the Euler's number e are irrational numbers. The exact values of π and e are 3.14159 and <span>2.71828182846, respectively. In reality, those decimal places go on a long way. Particularly, </span>π<span> has a total of 2.7 trillion digits. Numbers inside radicals or roots can also be irrational numbers. For example </span>√3 is irrational because it is equal to 1.732050808. However, not all radicals are irrational. For example √15.3664 is equal to 98/25 or 3.92. That is a rational number. So, therefore, use the calculator to know the exact value of the term to properly distinguish rational from irrational.

I need some help solving for x! Thanks :)
slega [8]

Given:

The figure of a rhombus.

To find:

The value of x.

Solution:

We know that, if two lines intersect each other, then the vertically opposite angles are equal.

From the given figure it is clear that the diagonals intersect each other and construct two pairs of vertically opposite angles.

Since 95^\circ and x^\circ are vertically opposite angles, therefore

x^\circ=95^\circ

Hence, the value of x is 95°.

F=32+1.8c. This is in slope intercept form, so 32 is the Y intercept, and the slope is 1.8(9/5).
