A photographer uses an online service to sell some of his work. The amount of money he will make from selling 10 copies of the s
VLD [36.1K]

Answer:

Step-by-step explanation:

The expression representing the amount of money that the photographer would make from selling 10 copies is given as

10(0.75p - 0.5)

where p represents the price determined for each copy. Assuming the price charged per copy is $5, then the amount made from 10 copies is

10(0.75 × 5 - 0.5) = $32.5

It could have been

10(5 - 0.5) = $45

The price is being reduced by 25%(100 - 75)

Therefore, the option that most likely describes the agreement between the online service company and the photographer is

A. The company keeps 25% of the amount paid for each copy and charges the photographer $0.50 for every copy purchased.

For each order pair (x,y) , determine whether it is a solution to the inequality 4x-6y_< - 18
anyanavicka [17]

Solution:

Given:

4x-6y\leq-18

To determine if an ordered pair is a solution, we substitute the x and y-values into the inequality and check if it is true.

Thus,

\begin{gathered} For\text{ the point }(-9,-2) \\ x=-9,y=-2 \\ 4x-6y\leq-18 \\ 4(-9)-6(-2)=-36+12=-24 \\ Since\text{ }-24

\begin{gathered} For\text{ the point }(0,3) \\ x=0,y=3 \\ 4x-6y\leq-18 \\ 4(0)-6(3)=0-18=-18 \\ Since\text{ }-18=-18,\text{ then }(0,3)\text{ is a solution} \end{gathered}

\begin{gathered} For\text{ the point }(5,-3) \\ x=5,y=-3 \\ 4x-6y\leq-18 \\ 4(5)-6(-3)=20+18=38 \\ Since\text{ }38>-18,\text{ then }(5,-3)\text{ is not a solution} \end{gathered}

\begin{gathered} For\text{ the point }(8,5) \\ x=8,y=5 \\ 4x-6y\leq-18 \\ 4(8)-6(5)=32-30=2 \\ Since\text{ }2>-18,\text{ then }(8,5)\text{ is not a solution} \end{gathered}

Therefore, the correct answers are selected as shown below;
