Answer:
k = -3
Step-by-step explanation:
log7(-5k - 3) = log7 (-4k)
---> -5k - 3 = -4k
-k - 3 = 0
k = -3
The difference quotient of the function that has been presented to us will turn out to be 5.
<h3>How can I calculate the quotient of differences?</h3>
In this step, we wish to determine the difference quotient for the function that was supplied.
To begin, keep in mind that the difference quotient may be calculated by:
Lim h->0 
Now, for the purpose of the function, we need this:
Then we will have:

j(x) = 5x - 3
Then the following will be true:
Therefore, 5 is the value of the difference quotient for j(x) is %

Step-by-step explanation:
Answer:
The day's high temperature written as degrees Celsius is 25 degrees' Celsius.
Step-by-step explanation:
The day's high temperature in St. Louis ,Missouri was recorded as 77 degrees F.
We are supposed to find the day's high temperature written as degrees Celsius.
Formula : 
Substitute the value of F is 77 degrees
So,

C=25
Thus, The day's high temperature written as degrees Celsius is 25 degrees' Celsius.
