it cost $5 to send 6 packages through a certain shipping company. consider the number of packages per dollar.
b. find the constant of proportionality for this situation.
a. write an equation to represent the relationship.

A) The equation is y = 5/6x

B) The constant of proportionality is 5/6

Step-by-step explanation:

If it cost $5 to send 6 packages, you can write this as 5 over 6 (5/6), as 5 representing y and 6 as x. So the first equation is k = y/x, so in this case it can be written as k = 5/6. Then it can be written as y = kx, so in this case it will be y = 5/6x

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
