Answer:

The sum of 4 and an integer.

Step-by-step explanation:

To solve this problem we need to transform the expression written in an algebraic form to a verbal statement.

In this expression, first of all we can notice that the operation given is a sum.

One of the numbers is 4 and the other number is represented by the letter k. Since we are not given any conditions on the k, we could say that k is any number (although in math, the k usually represents an integer, so we'll consider k to be an integer).

Thus, 4 + k would be expressed as "the sum of 4 and an integer"

Answer:

B. $f^{-1}(x)=\frac{x-4}{5}$

Step-by-step explanation:

To find the inverse of a function/equation:

Replace f(x) with y: y=5x+4
Switch x and y: x=5y+4
Solve for y: x-4=5y -> $y=\frac{x-4}{5}$
Write in standard inverse notation: $f^{-1}(x)=\frac{x-4}{5}$

I hope this helps!!

Got you. So we will use the basic formula for the area of a rectangle and insert variable values. (^_^)

Area= Width(Height) ----------- Insert values of width and height [width = (x-1)
, height = (x+9)]

Area= (x-1)(x+9) ) -------------- Then expand if needed?
= x² +8x -9
