Answer:

A

Step-by-step explanation:

We assume the opposite and then get to a point where we get a false statement. That proves that the the opposite of the opposite (What we originally wanted to prove) is true.

In imaginary numbers can you multiply two radicals that have negative values under them that do not square to whole numbers
ElenaW [278]
Yes, you can; based on the inherent assumption that the "two radicals that have negative values" are, in fact, "imaginary numbers" .

Take, for example, the commonly known "imaginary number":  "i" ;  which represents the "imaginary number" ;  " √-1 " .

Since:  "i = √-1" ; 

Note that:   " i² = (√-1)² = √-1 * √-1 = √(-1*-1) = √1 = 1 .

Find an equation of the line that contains the given pair of points. ​(negative 4 ​, 7 ​), ​(minus 2​,minus7 ​) The equation of

Answer:

y=-7x-21

Step-by-step explanation:

We have been given two points on a line as (-4,7) and (-2,-7). We are asked to find the equation of the line passing through these points.

We will write our equation in slope-intercept form y=mx+b, where m represents slope of line and b represents the y-intercept.

Let us find slope of line using our given points as:

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-7-7}{-2-(-4)}

m=\frac{-14}{-2+4}

m=\frac{-14}{2}

m=-7

Now, we will substitute m=-7 and coordinates of point (-4,7) in slope-intercept form of equation as:

7=-7(-4)+b

7=28+b

7-28=28-28+b

-21=b

Substitute -21=b and m=-7 in slope-intercept form of equation:

y=-7x-21

Therefore, our required equation would be y=-7x-21.
