Answer:  The correct answer is (B) (4-i).

Step-by-step explanation:  We are given to select the correct complex number that will be plotted below the real axis and to the right of the imaginary axis.

We know that a complex number can be treated as a point in XY-coordinate plane as X-axis is the real axis and Y-axis as the imaginary axis.

That is, x + iy = (x, y).

Therefore, the given points and the corresponding quadrants can be written as

2i - 5 = (-5, 2)        Quadrant II

4 - i = (4, -1)           Quadrant IV

5 + i = (5, 1)           Quadrant I

-5i   = (0, -5)          Y-axis

-2 - i = (-2, -1)        Quadrant III.

Now, the quadrant that lies below the X (real) axis and to the right of Y (imaginary) axis is Quadrant IV.

So, the correct complex number that will be plotted below the real axis and to the right of the imaginary axis is (4 - i).

Option (B) is CORRECT.

Answer:

x = 3, the error is that the -2x should be added.

Step-by-step explanation:

The -2x should be added to the left side.

3x - 7 = -2x + 8

3x + 2x = 8 + 7

5x = 15

x =3

Use one or more properties to rewrite the expression as an equivalent expression that does not use parenthesis. (5+10p)+13. A. 2
bulgar [2K]
It will be D. because you have to add the like terms which is 13 + 5 which will be 18 and so 10p doesn't have no like terms it just stays the same so it will be 10p+18

Answer:

8 1/2 hrs/wk

Step-by-step explanation:

3(1 1/2 hrs) plus

2(1 1/4 hrs) plus

2(3/4 hr)

The LCD here is 4.  Convert 3(1 1/2 hrs) to 3(1 2/4 hrs), so that we now have:

3(1 2/4 hrs)  = 3 6/4 hrs

+2(1 1/4 hrs)  =  2 2/4 hrs

+2(3/4 hrs)   =       6/4 hrs

-------------------------------------

                          5 14/4 hrs, or

                          5 + 3 2/4 hrs, or

                              8 1/2 hours/week
