Answer:
use Pythagoras theoreom and try to solve it
-1.1 should be the right answer
Solving the complex number, we get the value of the missing value that is ‘a’ = -6
We have been given the expression as
|a – i| = √37 (1)
Which is an expression of complex number. The general expression of complex number is given as
z = x + iy
where x is the real part and iy is the imaginary part
To find the modulus value, the formula is given by,
|z| = |x + iy|
|z| = √[(real part)2 + (imaginary part)2]
|z| = √(x2 + y2)
According to the question, |z| = √37 (2)
Equating equation (1) and (2), we get
√(a2 + 1) = √37
(a2 + 1) = 37
a2 = 37 – 1
a2 = 36
a = √36
a = ±6
Now value of a can be 6 or -6. We have been given that the modulus is in third quadrant.
Hence the value will be negative. Therefore, the missing value will be -6.

Answer:
2y -10 > 13
Step-by-step explanation:
Answer:
-5x + y = -27
Step-by-step explanation:
Equation: y+8 = -5(x+3)
Standard form is (ax + by = c)
We have to get x and y and their coefficients over to the left side of the equation, and all the single numbers to the right side.
y + 8 = -5 (x + 3)
y + 8 = -5x -15
y = -5x - 27
THE ANSWER IS :
-5x + y = -27
