Joyce wants to has an areat a rectangular gat least 300 square meters and a perimeter of at least 70 meters. If the length of the garden is \( x \) meters long and the width is \( y \) meters long, which of the follow systems of inequalities represents Joyce's requirements?

b. \( \left\{\begin{array}{l}\frac{1}{5} x+2=y \\ \frac{5}{3} x-y=4\end{array}\right. \)

price changes to bring supply and demand into balance. supply changes to bring demand into balance. quantity changes to brings supply and demand

Factor the trinomial completely. \[ 6 x^{2} y+90 x y-66 y \]

Factor the trinomial completely. If the trinomial contains a greatest common factor (other than 1 ), factor out the GCF first. \( 5 t^{5}-30 t^{4}+40 t^{3} \)

x) \( \left.\begin{array}{rl}x+y+z & =6 \\ x+y & =3 \\ +y+z & =5\end{array}\right\} \)
