What is the equation of the following line? Be sure to scroll down first to see all answer options.

Serjik [45]

Answer:

<h3>The answer is option F</h3>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To calculate the equation of the line first find the slope

Slope of the line using points

(0 , 0) and (4 , -2) is

$m = \frac{ - 2 - 0}{4 - 0} = \frac{ - 2}{4} = - \frac{1}{2}$

Now use the formula

y - y1 = m(x - x1) to find the equation of the line using any of the points

Using point (0,0)

That's

$y - 0 = - \frac{ 1}{2} (x - 0)$

The final answer is

$y = - \frac{1}{2} x$

Hope this helps you

Leap years are years in which February has 29 days instead of 28. The device of leap year was invented to keep the calendar in s

goldenfox [79]

Answer:

As you know, a year has around 365 + 1/4 days.

This means that in two years, we have:

365 + 356 + 1/4 + 1/4 = 730 + 1/2

and so on.

adding this up, when we have 4 years we have a full day extra, this is:

1460 + 1

When we divide 1461 by 4, we have 365 with a surpass of 1.

The rule used to keep the calendar in sync with this extra day is adding an extra day to each fourth year.

So each fourth year, we have an extra day in Februray (the Februray 29th), this is called a bisiest year.

The "math rule" used to know if a year is leap or not is:

if a year is not divisible by 4, then it is a common year

else if the year is not divisible by 100 then it is a leap year,

else if the year is not divisible by 400, then it is a common year

if not, the year is a leap year.

Where "year" represents the number of the year.

For a Chinese New Year celebration, James and Zhou are making a dragon costume similar to the one shown above.

Lilit [14]

Answer:

C. 24 meters

Step-by-step explanation:

Given:

Total length of fabric required for the costume = 56.6 m

Length of fabric Zhou already has = 15 m

Length of fabric James just purchased = 17.6 m

To find how much more length of fabric is required to make the complete costume.

Solution:

<em>Let the length of fabric in meters still required be</em> = $x$

<em>The total length can be given as :</em>

⇒ $(15+17.6+x)\ m$

⇒ $(32.6+x)\ m$

The total fabric required = 56.6 m

So, the equation to find $x$ will be:

$32.6+x=56.6$

Subtracting both sides by 32.6

$32.6+x-32.6=56.6-32.6$

∴ $x=24$

Thus,<u> 24 meters</u> of fabric is still required to make the costume.
