Find the difference of the complex numbers.
(2 +8i)-(-5 - 3i)
Answers
Answer:
7 + 11i
Step-by-step explanation:
Simplify: (2 +8i)-(-5 - 3i) = 2 + 8i + 5 + 3i
Add real numbers to real numbers and imaginary to imaginary: 2 + 8i + 5 + 3i = 7 + 11i
A complex number can be shown as a pair of integers (a, b). The difference of the complex number (2 +8i)-(-5 - 3i) is 7+11i.
What is a complex number?A complex number can be shown as a pair of integers (a, b) forming a vector on an Argand diagram, which represents the complex plane.
The difference of the complex number can be done as following,
(2+8i)-(-5-3i)
= 2 + 8i + 5 + 3i
= 5+2 + 8i+3i
= 7 + 11i
Hence, the difference of the complex number (2 +8i)-(-5 - 3i) is 7+11i.

AABChas coordinates A (-4,-2), B(0,4), and C(4,-2). Find the midpoint of AC.
Answers
Answer:
( 0, - 2 )
Step-by-step explanation:
Mid point formula : -
( x1 + x2 ) / 2, ( y1 + y2 ) / 2
Here,
Let ( x1, y1 ) = ( - 4, - 2 )
Therefore,
x1 = - 4
y1 = - 2
Let ( x2, y2 ) = ( 4, -2 )
Therefore,
x2 = 4
y2 = - 2
Midpoint of AC
= ( - 4 + 4 ) / 2, ( - 2 - 2 ) / 2
= ( 0 / 2, - 4 / 2 )
= ( 0, - 2 )
The midpoint of AC is ( 0, - 2 ) when coordinates of A (-4,-2), B(0,4), and C(4,-2) is given.
What is the Midpoint of a Line?
The midpoint of a line is a point that is equidistant from the endpoints of the line and in the middle of the line. If the endpoints of the line are (x)1, (y)1, and (x)2, (y)2, then the formula for the midpoint of the line is {[(x)1 + (x)2]/2, [(y)1 + (y)2]/2}.
Mid point formula is given as : -
( x1 + x2 ) / 2, ( y1 + y2 ) / 2
Here,
Let ( x1, y1 ) = ( - 4, - 2 )
x1 = - 4
y1 = - 2
Let ( x2, y2 ) = ( 4, -2 )
x2 = 4
y2 = - 2
now using Midpoint formula to find the coordinates of AC
= ( - 4 + 4 ) / 2, ( - 2 - 2 ) / 2
= ( 0 / 2, - 4 / 2 )
= ( 0, - 2 )
Therefore, the midpoint of AC is ( 0, - 2 )

Answers
Answer:
-25 and 4
Step-by-step explanation:
Two numbers that multiply to the value on top and add to the value on bottom
Value on top = -100
Value at bottom = -25
Numbers that multiply to give -100 = -10 × 10, -20 × 5, -25 × 4, - 50 × 2,
Of all the above, - 25 × 4 = -100
-25 + 4 = -21
Value at bottom = -25
Therefore, the two numbers are -25 and 4
-25 × 4 = -100
-25 + 4 = -21
