Which of the following is a conjugate for 7 + isquare root of 2?

7 - i

Step-by-step explanation:

Given a complex number a ± bi then the complex conjugate is

a ∓ bi

Note that the real part remains the same while the sign of the coefficient of the imaginary part is the opposite

Hence conjugate of 7 + i is 7 - i

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
