We can not evaluate it with real numbers, because there is no real number that multiplies itself twice and gives -25.
The answer is an imaginary number.
√-25 = 5i where i = √-1
So it can only be computed using imaginary numbers.
Answer:
2=173
4=309
7=513
9=649
Step-by-step explanation:
Since she starts with 37MB already download 37 will be a constant and for every second she is home she downloads 68 more MBs so to get the answers for the table you just have to do 37+ 68*(the number of seconds)
2=37+68(2)=173
4=37+68(4)=309
7=37+68(7)=513
9=37+68(9)=649
Solution,
y = -x-4......(i)
3x + y =- 16.......(ii)
Now,
Substituting the value of y in equation (ii)
or, 3x + (-x-4)= -16
or,3x - x - 4 = -16
or, 2x= -16 +4
or, x = -12/2
: x = -6
Then,
Substituting the value of x in (i) equation;
or,y= -(-6) - 4
or,y= 6 - 4
: y =2
