Question

Find y in each equation if x = 16

Answer 1

Answer: -3 and 11

Explanation:

y
= root(x)-7
= root(16) -7
= 4-7
= -3

y
= 4+modulus (9- x)
= 4+modulus (9-16)
= 4+modulus(-7)
= 4+ 7
= 11

Answer 2

y = -3

y = 11

Explanation:

`y = √(x) -7` where x = 16

`y = √(16) -7\\`

y = 4 - 7

y = -3

y = 4 + I9 - xI where x = 16

y = 4 + I9 - 16I

y = 4 + I- 7I

y = 4 + 7

y= 11
