Answer:

y = 9.65x

Step-by-step explanation:

Given that total revenue is directly proportional to the number of units sold

Let the number of units sold be represented by x and the total revenue be represented by y

Given y∝x

y = kx where k is some constant

Also given that when 500 units are sold, the total revenue is $4825.

Here y=4825 and x=500

Now 4825= k\times500

k=9.65

Therefore the equation representing the relation between the total revenue and the number of units sold is

y = 9.65x

If W + 6 = 3 and v-4 = 2, what is the value of w + v?
OLEGan [10]

Answer:

w = - 3 and v = - 2

Step-by-step explanation:

Because w + 6 = 3 you would subtract 6 and whatever you do to one side you would do to the other.

w= - 3

Write the equation of a piecewise function with a jump discontinuity at x =3. Then, determine which step of the 3-step test for
seraphim [82]

Answer:

Here's a possible example:

Step-by-step explanation:

f(x) =\begin{cases} x & \quad x < 3\\x+3 & \quad x \geq 3\\\end{cases}

Each piece is linear, so the pieces are continuous by themselves.

We need consider only the point at which the pieces meet (x = 3).

\displaystyle \lim_{x \longrightarrow 3^{-}} f(x) = \lim_{x \longrightarrow 3^{-}} x = 3\\\\\displaystyle \lim_{x \longrightarrow 3^{+}} f(x) = \lim_{x \longrightarrow 3^{+}} x+3 = 6\\\\f(3) = x + 3 = 6\\\\\displaystyle \lim_{x \longrightarrow 3^{-}} f(x) \neq f(3)

The left-hand limit does not equal ƒ(x), so there is a jump discontinuity at x =3.
