Mathematics

Delicious77 [7]3 years ago
4 0

Answer:

x=0

y=-21/7

Step-by-step explanation:

Let the two unknown be x and y

x+y=-7...(1)

x-y=14...(2)

From (1) make x the subject of formula

x=-7-y...(3)

Substitute (3) into (2)

-7-y-y=14

-7-2y=14

Add 7 to both sides

-2y=21

Add both sides by-2

y=-21/2

Substitute the value of y into (3)

x=-7-(-21/2)

x=-7+21/3

Lcm

x=-21+21/3

x=0/3

x=0

Rewrite the square-root expression as an imaginary number: sqrt of -64<br><br> is it 8i?
IceJOKER [234]
The answer is 8i.

i = √(-1)

√(-64) = √((-1) * 64)
           = √(-1) * √64
           = i * √8²
           = i * 8
           = 8i
