The sales tax for an item was $8.80 and it cost $440 before tax.

PilotLPTM [1.2K]

Answer:

Step-by-step explanation:

In non-mathematical form, the question is asking $8.80 is what percent of $440. N will equal the percent. So, you would set up the equation like this: 20 = N · 440

You need to solve the equation.

20/440 = N · 440/440

0.045 repeating = N

Rounded, the sales tax rate would be 4.5%

Functions f(x) and g(x) are shown below. f(x) = x2. . g(x) = x2 - 8x + 16. In which direction and by how many units should f(x)

Aliun [14]

The original function is given by:
$f (x) = x ^ 2
$
We apply the following transformation:
Horizontal displacements:
Suppose k> 0
To move the graph k units to the right, we must graph f (x-k)
Applying the transformation for k = 4 we have:
$g (x) = f (x-4)

g (x) = (x-4) ^ 2

g (x) = x ^ 2 - 8x + 16$
Answer:
B. Right by 4 units
