-v= -1v; -v÷-1 = k÷-1; The answer is v =k ÷ -1
Answer:
G
Step-by-step explanation:
N = 1 corresponds to day 1
n = 2 corresponds to day 2
...etc etc...
n = 21 corresponds to day 21
Plug in n = 21
a_n = 100 + (n-1)*4
a_21 = 100+(21-1)*4 ... replace every n with 21
a_21 = 100 + 20*4
a_21 = 100+80
a_21 = 180
Answer: C) 180 yards
Use the rule that x^(-k) = 1/(x^k) to get
(-3)^(-5) = 1/( (-3)^5 ) = 1/( -243 )
Comparing 1/( -243 ) with the form 1/x, we see that x = -243
<h3>Answer: -243</h3>
