A time line is a useful way to represent important dates and events throughout history. It's common to divide a historical time line into events that occurred either BC (to the left of zero) or AD (to the right of zero). The year you're living in right now takes place in AD. BC AD 0 When performing mathematical operations involving dates, we can think of a historical time line as a number line. On the number line, the years increase from left to right. If zero represents the origin, the years to the right of zero are considered positive numbers and the years to the left of zero are considered negative numbers. Using this analogy, here are some events that might appear on a historical number line:
Event Historical Time Line Number Line

(The first ancient games take place in Olympia, Greece. 776 BC -776)

(Construction begins on the Great Wall of China. 221 )

(BC -221 World War I begins in central Europe. AD 1914 1,914 (or 1914)

Use these ideas about time lines and number lines to answer the questions that follow.
Part A The year in which the US Civil War ended was 25 percent later than the year Christopher Columbus set sail from Spain. If c represents the year Columbus set sail, we can write the year the Civil War ended as C +0.25c.

Step-by-step explanation:

1 feet = 12 inches

Note : We just need to judge whether it accords with "y = kx"

{Proportional relationship}

Answer:

y = (-3/4)x - 1/4

Step-by-step explanation:

Use the slope-intercept formula y = mx + b.  Here m = -3/4 and b = -1/4, and so:  y = (-3/4)x - 1/4

The equation of the line with slope  -3/4 and y-intercept is -1/4 is y=-3/4x-1/4.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of the line is the ratio of the rise to the run, or rise divided by the run.

It describes the steepness of line in the coordinate plane.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Given that the slope is -3/4 and y-intercept is -1/4.

We have to find the equation of line with slope -3/4 and y-intercept is -1/4.

m=-3/4 and b = -1/4

Now plug in these values in slope intercept form y=mx+b

y=-3/4x-1/4

Hence, y=-3/4x-1/4 is the equation of the line with slope  -3/4 and y-intercept is -1/4.

Answer:

-27/2

Step-by-step explanation:

Hello and Good Morning/Afternoon

Let's take this problem step-by-step:

What does this problem want us to find:

[tex]\hookrightarrow \text{The slope-intercept form}: y= mx + b[/tex]

Let's find the slope:

    [tex]m = \dfrac{y_2-y_1}{x_2-x_1} = \dfrac{2-3}{4-0} =-\dfrac{1}{4}[/tex]

Let's find the y-intercept:

 ⇒ the value of the y-coordinate when the x-coordinate value is '0'

    ⇒ thus it is '3'

Our equation is:

 [tex]y=-\dfrac{1}{4} x+3[/tex]    <=====  Answer

Greetings from Brasil...

One way to solve this question is through a determinant.

| X     Y     1 |

| X₁    Y₁    1 |  = 0

| X₂    Y₂   1 |

as

(X₁; Y₁) = (0; 3)

(X₂; Y₂) = (4; 2)

then

| X   Y  1 |

| 0   3   1 |  = 0

| 4   2   1 |

Answer:

Triangles are congruent if their corresponding sides are congruent using SSS postulate.

Answer:

Step-by-step explanation:

Triangles are congruent if their corresponding sides are equal.  If this is the case, each side of one triangle is matched perfectly by the corresponding side of the other triangle.

Hello!

Inequality: [tex]-1.2z-8.2 > -9.7[/tex]

To solve, we need to add 8.2 to both sides of the inequality:

[tex]-1.2z-8.2+8.2 > -9.7+8.2\\-1.2z > -1.5[/tex]

Now to get our solution, we will need to divide both sides by -1.2:

[tex]\frac{-1.2z}{-1.2} > \frac{-1.5}{-1.2}\\[/tex]

Final answer:

Answer:

[tex]5.45 * 100000[/tex]

Other:

[tex]545000[/tex]

Answer:

A

Step-by-step explanation:

Looking at the number line, you will notice that A, B, and C are less than 0.

Eliminate D, which is greater than 0.

Further still, as negative numbers get 'smaller', they go from -1 to -∞.

i.e.: -1 > -2 > -3

if you forget the above fact, looking at the number line, you can see that A is between -1 and -2, and [tex]-1\frac{5}{8}[/tex] is between -1 and -2 just as [tex]1\frac{5}{8}[/tex] is between 1 and 2.

Then, simply counting the ticks from -1 to -2, you can see that A falls on the 5th tick, while -2 falls on the 8th tick from -1.

Answer:

42 - 12 ÷ 6 = 40

(6 - 3) x 4 - 7 = 5

Step-by-step explanation:

First of all, when coming over to an equation with a division or multiplication sign, we first solve the division or multiplication first, then the subtraction or addition. So, 12 ÷ 6 = 2. Then, 42 - 2 = 40. And in the other one we must first solve what's in the parenthesis. So, 6 - 3 = 3. Then, we multiply, 3 x 4 = 12. Then subtract. 12 - 7 = 5.

Answer: 20c + 10.

Step-by-step explanation:

(c represents crates)

I wrote each equation separately first.

Supplier A: 4c + 6

Supplier B: 6c - 1

Supplier C: 10c + 5

We can add all the cs from each supplier giving us 4c + 6c + 10c which equals 20c. Now we can add the extra shoes as, 6 + (-1) + 5 equaling 10. I wrote -1 because we are missing that shoe, but you can write it as 6 - 1 + 5 instead. Together the two numbers make the equation 20c + 10. Hope that helps : )
