It is B. Because the 3$ doesn't have any variables and the 2 dollars is per hours so 2x
Yes they will be equal at some point. Although Marc has more miles on his car at the current moment, Elena is adding miles at a higher rate.
Elena's car: 7000 + 21000t
Marc's car: 20000 + 11000t
To find at what time t they are equal, set these two expressions equal to each other and solve for t.
7000 + 21000t = 20000 + 11000t
13000 = 10000t
t = 1.3 years from now
Answer:
-1
Step-by-step explanation:
They already did the opposite reciprocal for you.
They have it in the form 
now.
To find b you just enter (x,y)=(8,1).
Let's do that.
Subtract 2 on both sides:
b=-1
Answer:
10000 x (1.001438)^4t
Step-by-step explanation:
Using the compound interest formula Accrued Amount = P (1 + r/n)^n t
where Accrued amount is to be determined
P = principal; $10000
r = 5.75% = 0.0575
n = number of times interest is applied annually = 4 for quarterly
t = number of years
Therefore
Accrued Amount (A) = 10000 x (1 + (0.0575/4))^(4t)
= 10000 x (1 + (0.001438))^(4t)
= 10000 x (1.001438)^4t
which can then be solved by varying t, the number of years
