Answer:
10
Step-by-step explanation:
Given expression is .
is a complex expression.
The value of<em> i </em>is –1.
By definition of absolute value,
Now, substitute in the above formula.
(since <em>i </em>= –1)
(since
and
)
(Square root of 100 is 10)
= 10
Hence, the value of the expression is 10.
B) If the line is parallel, that means the slope is the same.
The slope for the original line is
= 
.
The second form of coral line would be y = -1/4x + (any number). You could use y = -1/4x + 3.
c) Solve 12x = 24 + 3y for y.
3y = 12x - 24
y = 4x - 8
Perpendicular lines have negative reciprocal slopes... the negative reciprocal for -1/4 is 4. So yes, the third coral structure is perpendicular to the first coral.
