Answer:
The 85 term of the arithmetic sequence would be 983
Step-by-step explanation:
Use the formula: an=a1+(n−1)d
an=a1+d(n-1)
a85= -25+(85-1)12
a85= -25+1008
a85=983

Answer:
B
Step-by-step explanation:
if we divide both sides of 6x + 9 = 12 by 3

Answer:
Step-by-step explanation:
Given that prices for a pair of shoes lie in the interval
[80,180] dollars.
Delivery fee 20% of price.
i.e. delivery fee will be in the interval [4, 9]
(1/20th of price)
Total cost= price of shoedelivery cost
Hence f(c) = c+c/20 = 21c/20
The domain of this function would be c lying between 80 to 180
So domain =[80,180]
---------------------------------
Amount to be repaid = 42 dollars
Once he received this amount, the price would be
105+42 =147
But since price range is only [21*80/20, 21*180/20]
=[84, 189]
Since now Albert has 147 dollars, he can afford is
[80,147]
