Answer:
f(x) = -5/9 x + 5 1/9
Step-by-step explanation:
f(2)=4 and f(−7)=9 means the line pass through (2,4) and (- 7,9)
f(x) = mx + b
m = (y-y') / (x-x') = (9 - 4) / (- 7 - 2) = - 5/9
for (2,4) : b = f(x) - mx = y - mx = 4 - (- 5/9) x 2 = 4 + 10/9 = 46/9 = 5 1/9
f(x) = -5/9 x + 5 1/9
check for (-7, 9) f(-7) = (-5/9) * (-7) + 5 1/9 = 35/9 + 46/9 = 81/9 = 9
Answer:

Step-by-step explanation:
These are the terms of a geometric sequence with n th term
= a
Where a is the first term and r the common ratio
r = 
= 
= 
= 2
and a = 5, hence explicit equation is
= 5
6 is in the tenths place.

Answer:
3: 101.00
Step-by-step explanation:
This is a trick question. It says that Shelby wants to go with THREE other friends and implies that she is going too. So that means there are 4 people going. Hence, do 25.25*4=101.
