A pillow that usually costs $18 is marked down 25%. Use the table to find the pillow’s new price.
snow_tiger [21]

It would be 13.50 because 50% off of 18$ is 9$ but it’s not 50% off itS 25% off so If you take the 50% Off price of 9$ and add 4.50 (One more 1/4th) you get $13.50

Solve the system of equations graphicallySolution=?
BigorU [14]

The given system is

\begin{cases}y=\frac{5}{2}x-8 \\ y=-\frac{1}{2}x-2\end{cases}

Given that y = y, let's combine the equations

\frac{5}{2}x-8=-\frac{1}{2}x-2

Let's solve for x

\begin{gathered} \frac{5}{2}x+\frac{1}{2}x=8-2 \\ \frac{6}{2}x=6 \\ 3x=6 \\ x=\frac{6}{3} \\ x=2 \end{gathered}

Then, we find y

y=-\frac{1}{2}x-2=-\frac{1}{2}\cdot2-2=-1-2=-3

The solution is (2, -3).

The image below shows the solution graphically.

Answer:   L=90-10t

0-90

1-80

2-70

3-60

Step-by-step explanation:

that should be right lol

because it decreases by ten a week so just count down by ten each week. Then, you can make the equation 90-10t and if you substitute each week for t it is true.

90-10(0)=90-0=90

90-10(1)=90-10=80

and so on...
