Answer:

f^{-1}(x) = \frac{x}{5}

Step-by-step explanation:

f^{-1}\left( x\right)  =y\Longleftrightarrow f\left( y\right)  =x

…………………………

f(y) = x

⇔ 5y = x

\Longleftrightarrow  y =\frac{x}{5}

\Longleftrightarrow  f^{-1}(x) = \frac{x}{5}

Marco was shopping for markers and lead pencils. The cost of markers is $4, and the cost of each lead pencil is $3. If Macro can
never [62]

This shows that Marco can buy at most 5 pencils

<h3>Inequalities</h3>
  • Let the price of each pencil Marco can  buy be "x"

If the cost of markers is $4, and the cost of each lead pencil is $3 with at most $15 spent, hence;

  • 4 + 3x ≤ 15

Subtract 4 from both sides

3x  ≤ 15

x ≤ 15/3

x ≤ 5

This shows that Marco can buy at most 5 pencils

A cell phone costs $170 and has a tax rate of 7%. Write and Solve a proportion to find how much tax is paid on the cell phone.
daser333 [38]

Answer:

$11.9

Step-by-step explanation:

We are given;

The cost of the cell phone is $170

Tax rate is 7%

We are required to find how much tax is paid on the cell phone.

The tax rate is 7% of the cost of the cell phone

That is;

7% of $170

also; 7/100 of $170

Thus, tax paid = 7/100 × $170

                        = $11.9

Thus, the tax paid on the cell phone is $11.9
