1. Solve the following inequalities and describe the similarity and differences be-
tween the solution set:

a) 1 + x < 2
b) 1 − x < 2
c) −1 − x < −2
d) −1 − x < 2

The correct way of writing the equation of the line that passes through the points are y = -3x - 5.

Two expressions are combined by the equal sign to form a mathematical statement known as an equation. For instance, a formula might be 3x - 5 = 16. After solving this equation, we learn that the value of the variable x is 7.

The slope-intercept form, point-slope form, and standard form are the three primary types of equations. These equations provide sufficient details about the line to make graphing them simple.

Answer: look at the graph below

Step-by-step explanation:

Consider the given system of equation

x + y = -7     ........(1)

4x + y = 19   ..........(2)

Consider the equation (1)

x + y = -7

We first find different values of x and y that satisfies (1),

1) x = 1 , y = -7-1 = -8  

We get one point as (1,-8)

2) x= 2 , y = -7 -2 = -9

We get  point as (2 ,-9)

3) x = 0 , y = -7

We get point as (0 ,-7)

Similarly, find different values of x and y that satisfies (2),

4x + y = 19  

1) x = 2 , y = 19 -  8 = 11

We get  point as (0,11)

2)  x= 3 , y = 19 - 12 = 7

We get  point as (3 , 7)

3) x= 4 , y = 19 - 16 = 3

We get  point as (4 ,3)

Now , we plot these point on the graph paper,  we obtained graph as, (as attached below)

Answer:

  P = (2, 7)

Step-by-step explanation:

You want to find coordinates of P on segment AB such that P is 3/4 is of the way from A to B.

For some fraction q of the distance from A to B, the point P that lies at that fraction of the distance is given by ...

  P = A +q(B -A) = (1 -q)A +qB

For q = 3/4, the location of P is ...

  P = (1 -3/4)A + 3/4B = (A +3B)/4

Using the given point coordinates, we have ...

  P = ((-4, -2) +3(4, 10))/4 = (-4 +12, -2 +30)/4 = (8, 28)/4

  P = (2, 7)

By consideration of congruence and collinearity, the value of x behind the geometric system formed by two collinear linear segments is equal to 3 / 8.

Two line segments are congruent when the line segments have the same length, then the following condition has to be fulfilled:

AB = BC      (1)

Where AB and BC are the lengths of the line segments AB and BC.

If we know that AB = 4 · x + 1 and BC = 20 · x - 5, then we solve the equation for x is:

4 · x + 1 = 20 · x - 5

6 = 16 · x

16 · x = 6

x = 6 / 16

Step-by-step explanation:

the diagonals in a square are intersecting each other at 90°.

that means that G1 + G2 = 90

and because of the symmetry of a kite, it also means that G1 = G2.

combined this tells us

G1 = G2 = 90/2 = 45°.

also due to its symmetry one of the rules of a kite is that its diagonals are also intersecting each other at 90°.

so,

E1 = E2 = 90°.

the sum of all angles in a triangle is always 180°.

so,

180 = F1 + G1 + (D2 + D3) = F1 + 45 + 110

F1 = 180 - 45 - 110 = 180 - 155 = 25°

again, due to the symmetry of the kite

F1 = F2 = 25°.

also

C2 + C3 = D2 + D3 = 110°

due to the properties of a square (e.g. the angle in every corner is 90°, the diagonals are splitting each corner angle in half) we know that

D1 = D2 = 45°.

and again, therefore

C1 = C2 = D1 = D2 = 45°

and so

(1)

due to the law of the angles of a line intersecting parallel lines are equal for every parallel line, we see that

the line BD intersects the lines AD and GEF equally at 45°. therefore, GEF || AD.

(2)

as we know that F1 = F2 = 25°,

F1 + F2 = 2×25 = 50°

(3)

the angles in the triangle GDE are

E1 = 90°

D2 = 45°

G1 = 45°

the angles of GE and DE with their baseline GD are equal, that means this is an isoceles triangle, meaning the legs have an identical length, and therefore

DE = GE.

(4)

as GDE is a right-angled triangle we can use Pythagoras :

GD² = GE² + DE² = 2×DE² = 2×GE²

GD = 3×sqrt(2)

GD² = 9×2 = 18

18 = 2×DE² = 2×GE²

DE² = GE² = 18/2 = 9

DE = GE = 3

The distance on the map is 3/4 inch

Given data

scale of the map = 1 inch : 2 miles

measurement from garage to the entrance of the skatepark = 3,520 feet

1 mile = 5,280 feet

The required measurement to convert to map measurement = 3520 feet

we solve for number of miles in 3520 feet knowing that 1 mile = 5,280 feet.  we solve this by:

5280 / 3520= 3 / 2 miles

so if scale of the map is 1 inch : 2 miles

The total number of Cubes that can be packed in the Rectangular Prism will be 84 Cubes

In the picture mentioned below, We have a Rectangular prism with the dimensions Length = [tex]3\frac{1}{2}[/tex] in, Breadth = 2 in, Height =  [tex]1\frac{1}{2}[/tex] in

Also, It is given that cubes of Dimension [tex]\frac{1}{2}[/tex] inches are to be packed in the Rectangular Prism.

Firstly, We need to find the volume of Both the Prism & the Cube.

Since, The it is a Rectangular Prism, Volume of cuboid = ( l*b*h )

Volume of Prism, V1 = l*b*h => l =[tex]3\frac{1}{2}[/tex], b = 2, h = [tex]1\frac{1}{2}[/tex]

                        => V1 = [tex]3\frac{1}{2} * 2 * 1\frac{1}{2}[/tex]    => V1 = 10.5 [tex]in^{3}[/tex]

Volume of Cube, V2 = l * l * l => l = [tex]\frac{1}{2}[/tex]

                       => V2 = [tex]\frac{1}{2} * \frac{1}{2} * \frac{1}{2}[/tex]       => V2 = 0.125 [tex]in^{3}[/tex]

To find out the number of cubes that can fit inside the prism we need to divide the volume of the prism by the volume of cube => V1/V2

                       =>  N =  [tex]\frac{V1}{V2}[/tex]  =>  [tex]\frac{10.5}{0.125}[/tex]

Answer:

[tex]5 { \\ }^{2} [/tex]

Step-by-step explanation:

exponents are ways to write multiplication powers 5

[tex]5 {}^{2} [/tex]

= 5×5 = 25

Answer:

Step-by-step explanation:

You want to know how multiplication and powers are related, and how powers can be evaluated.

You may be familiar with the fact that a coefficient is used to signify repeated addition:

  y + y + y + y = 4y

The coefficient of 4 in 4y signifies that y is in the sum that many times.

An exponent is used to signify repeated multiplication:

  y × y × y × y = y⁴ . . . . y to the fourth power

The exponent of 4 signifies that y is a factor in the product that many times.

In typeset text, the exponent is rendered in a superscript font. In plain text, the exponent (power) is identified using a caret (^):

  y⁴ = y^4

The rules of exponents derive from the idea of exponents signifying repeated multiplication:

  [tex](x\cdot x)=x^2\\(x\cdot x\cdot x)=x^3\\(x\cdot x)\cdot(x\cdot x\cdot x)=(x\cdot x\cdot x\cdot x\cdot x)\ \Longrightarrow\ x^2\cdot x^3=x^{2+3}=x^5[/tex]

Division has a similar rule.

  [tex]\dfrac{(x\cdot x\cdot x\cdot x\cdot x)}{(x\cdot x)}=(x\cdot x\cdot x)\ \Longrightarrow\ \dfrac{x^5}{x^2}=x^{5-2}=x^3[/tex]

This supports the idea that a positive exponent in the denominator is the same as a negative exponent in the numerator, and vice versa.

Powers can be evaluated in a straightforward way by carrying out the multiplications.

In general, the number of significant digits in the result will be the product of the exponent and the number of significant digits in the base.

For example, 9.2^5 could be expected to have 2×5 = 10 significant digits:

  9.2^5 = 9.2×9.2×9.2×9.2×9.2 = 65,908.15232

Most calculators are limited to 12 digits or less, and most spreadsheets are limited to 16 digits or less. Some special-purpose calculators have "variable" precision, so are able to properly render higher powers of numbers with more than 1 or 2 significant digits.

A calculator may use any of several techniques for evaluating powers. Among them might be ...

Logarithms turn a power problem into a multiplication problem:

  log(9.2^5) = 5·log(9.2)

Of course, once the logarithm is found, the issue of evaluating powers comes back:

  9.2^5 = 10^(5×log(9.2)) ≈ 10^(4.818939136727776)

Fortunately, there are methods of evaluating antilogs that simplify this part of raising to a power. The difficulty is that precision may be lost. Here, using the rounded value 10^(4.81893913673) gives the result 65,908.152320337..., which is in error after the 10th digit.

An integer power can be written as a sum of powers of 2. For example, ...

  37 = 32 +4 +1 = (8 +1)4 +1

Then ...

  9.2^37 = (((((9.2^2)^2)^2 · 9.2)^2)^2) · 9.2

This requires only 7 multiplications, not 36

__

Additional comment

Only the first token after the caret is considered to be the exponent:

  y^4x = (y^4)(x) . . . . . the first token is 4

  y^1/2 = (y^1)/2 = y/2 . . . . the first token is 1

If the exponent has multiple parts, they should be enclosed in parentheses:

  [tex]y^{3x+1}[/tex]

will be written in plain text as ...

  y^(3x+1)

and ...

  y^(1/2) = √y

You also need to be careful writing multiple exponents using the caret symbol. Parentheses are usually required. The Order of Operations has you evaluate multiple exponents right to left.

Step-by-step explanation:

We are given the following equation:

[tex]12x + 9 = 4x + 7[/tex]

In order to solve this equation, we have to rearrange it to make [tex]x[/tex] the subject of the equation:

[tex]12x + 9 = 4x + 7[/tex]

⇒ [tex]12x + 9 - 4x = 4x + 7 - 4x[/tex]       [Subtracting [tex]4x[/tex] from both sides]

⇒ [tex]8x + 9 = 7[/tex]

⇒ [tex]8x + 9 - 9 = 7 - 9[/tex]                     [Subtracting 9 from both sides]

⇒ [tex]8x = -2[/tex]

⇒ [tex]\frac{8}{8} x = -\frac{2}{8}[/tex]                                     [Dividing both sides by 8]

⇒ [tex]x = -\frac{2}{8}[/tex]

(A) Undefined terms are Point and Line.

(B)  Each point has at least two separate lines.

(C)  "P" does not lay on "m," hence the statement is contradictory.

A set of axioms from which one or more theorems may be logically deduced is known as an axiomatic system in mathematics and logic. A theory is a coherent, mostly self-contained body of knowledge that typically includes an axiomatic framework and all of the theorems that are deduced from it.

(A) Undefined terms are :

A location is a point. It is empty, meaning it has no width, length, or depth. A dot indicates a point.

A line is described as a collection of points that stretches in both directions indefinitely.

(B) Each point now has at least two separate lines.

A line 's' that is not incident on point 'P' must exist according to axiom 4 if we use point 'P' as our starting point.

Axiom 2 states that if a line exists, it must have the two points "R" and "S" on it.

(C) Since "P" does not lie on "m." P thus differs from 'e' and 's'

Points that stand out. They are different because they would be referred to as "m" if both lines "n" and I passed via "r" and "s."

However, "P" does not lay on "m," hence the statement is contradictory.
