<span>The intersection or point of intersection</span>
The given function is a linear function that decreases as the value of the
input <em>x</em> increases.
- The value of f(10), given f(x) = 9 - 2·x is option <u>A. -11</u>
Reasons:
The given function is f(x) = 9 - 2·x
The output of the function is the value of f(x) for a given input <em>x</em> of the function.
The input value, <em>x</em> is substituted into the function to obtain the output value, f(x).
Given that the input, x = 10
We have;
f(10) = 9 - 2×10 = -11
Therefore, the correct option for f(10) is <u>A. -11</u>

Answer:
$179.76
Step-by-step explanation:
We can calculate the total cost as follows. The 1.00 represents the before-tax cost of the dehumidifier and the 0.0575 the 5.75% sales tax:
Total cost of dehumidifier = (1.00+0.0575)($169.99) = $179.76 (to the nearest
cent()

Here's our expression: 
We will follow the order of operations and begin by solving everything in parentheses. 
Next, we solve the exponents. 
Now, we solve the multiplication and division. There is no division, so we will just solve the multiplication. 
Finally, we solve the addition and subtraction. Since there is no addition, we will solve the subtraction.
