Step-by-step explanation:
Use TOA method (tan angle = opposite / adjacent)
Given Opposite = x
adjacent = 6,

1. A, it is a function
2. A, it is not a function
Answer:
(2). <em>b - (a + c)i </em>
Step-by-step explanation:
= [( i )²]³ × i = ( - 1)³ i = - i
=
× i = i
a(- i ) + b( 1 ) - c( i ) = - ai + b - ci = <em>b - (a + c)i</em>
A veriable = 1, use it as with pemdas
rate :
======================
1 hours → 75 miles
? hours → (1125/75)
It takes her 15 hours to drive 1125 miles.
