$\huge\rm\purple{\underline{Line:-}}$

➜ A line is a figure in geometry which has only length with no breadth in a two dimensional plane , and extended infinitely in opposite directions .

➜ A line may be of any length and breadth . An infinite number of combination of long, short , thick or thin lines can Accord to their application unify , divide , balance , or unbalance a pictorial area . This emotion dynamic is set up by lines measures .

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━⠀⠀

$\large\sf\orange{\underline{Characteristics\:of\:line:}}$

Line type : dotted , short dashed , long dashed and continuous line.
Line width : extra dark , thick , medium annd thin
Line quality : the quality of line depends largely upon the drawing medium

Find the slope of the line through each pair of points

Elena-2011 [213]

Answer:

The slope of this line would be 10.

Step-by-step explanation:

In order to find the slope of the line, you would use the slope formula below.

m(slope) = (y2 - y1)/(x2 - x1)

m = (7 - -13)/(9 - 7)

m = 20/2

m = 10

Graph the linear inequality.<br> y<2

Leya [2.2K]

Answer:

See attachment.

Step-by-step explanation:

We want to graph the linear inequality y<2

We first of all graph the corresponding linear equation y=2 with a dashed line because all points on this line do not satisfy the inequality.

We then shade below the line y=2, to show that all points below the boundary line are solution to the inequality y<2

Why are radicals simplified before adding and subtracting? Explain your reasoning by adding the square root of 8 and the square

Rashid [163]

The reason they have to be simplified is that you cannot add radical unless the number under the radical is the same on all of them.

For example:

If you add √8 + √32 without simplifying, the best you could do is an estimate. But if you're required to put your answer in standard radical form this would be an issue.

So, you would have to simplify to combine:

√4√2 + √16√2
2√2 + 4√2
6√2

Hope this helped!

2. One of the most common mutagens in

vodka [1.7K]

Answer:

Ultraviolet (UV) radiation.

Step-by-step explanation:

Mutagen is part of genetics, it is chemical or physical agent which are present in atmosphere and causes changes or mutation in the genetic materials i.e. in DNA (these changes can be permanent as well). Example of mutagen are radioactive substances, ultraviolet radiation, etc.

UV radiation is an electromagnetic radiation which is present in sunlight. It is a strong mutagen which is when absorbed by DNA can cause extreme damage, for example, uncontrolled division of skin cell can cause skin cancer, that's the reason why UV radiation is the most common mutagen to which we are exposed to when we are outside in the sunlight.

Natali5045456 [20]

Step-by-step explanation:

f(x) = x² - 4

y = x²-4

x = y²-4

x + 4 = y²

$y = \sqrt{x + 4}$
