The domain of a function is the set of possible <em>input value</em>, the function can take.

The domain is [0,10]

The given parameters are:

Flat\ Fee = 15.25

Rate = 3.45

So, the function f(x) is:

f(x) = Flat\ Fee + Rate \times x

f(x) = 15.25 + 3.45 \times x

f(x) = 15.25 + 3.45x

Because x represents the <em>number of orders</em>, the value of x cannot be negative.

The teacher budgets $49.75.

This means that: f(x) = 49.75

So, we have:

49.75 = 15.25 + 3.45x

Collect like terms

49.75 - 15.25 = 3.45x

34.5 = 3.45x

Divide both sides by 3.45

10 = x

Rewrite as

x = 10

Hence, the domain is [0,10]

A line has the same slope as the line 3x+9y=5 and passes though the point (-1,2).what is the equation of the line?
MrRissso [65]

Answer:

y = -1/3x + 5/3

Step-by-step explanation:

First solve the equation. Simply put it is y = -1/3x + 5/9.

So, we have our slope which is -1/3. Now just plug it in.

y - y1 = m(x - x1)

y - 2 = -1/3(x - (-1))

Distribute.

y - 2 = -1/3x - 1/3

Add 2 to both sides

you get y=-1/3x + 5/3
