Answer:
linear function: y = -7x + 150
Step-by-step explanation:
Scott's situation represents a linear function because he is spending $7 each day on lunch. His initial amount in his bank account is $150 and each day he spends the same rate on lunch, $7. So, for any amount of days - represented by 'x' in the equation, you would multiply by -7 (since he is spending) and subtract this amount from his original amount of $150. In this equation, 'y' is equal to his total after 'x' amount of days.

Answer:
Step-by-step explanation:
a). 
= 
= 
= 
[Since, i = 
]
b). 
= 
= 
= 5 ± 2i [Since, i = ]
c). 
= 
= 
= 
= 
[Since, i = ]
Since the 6 is in the hundreds place and it is above 5, then you round the thousands place up one to 88000
