Answer:

Step-by-step explanation:
given

using the property of log
, and if c =
,
, we can rewrite our function as:

now we can easily differentiate:



This is our answer!
4z ≥ 7
divide seven by four
z ≥ 1.75
or, if you need it in fraction form, it would be
z ≥ 7/4
Answer:
Step-by-step explanation:
make y=0
0=-2x+3 (Switch the 3 sides)
-3=-2x (Divide everything by -2, cant have a negative x)
2/3=x or 0.66=x
5 would be the answer to it
Answer:
k
Step-by-step explanation:
The constant of proportionality is the ratio between two directly proportional quantities. ... Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
