Question
the graph shows some solutions to 0.25x + 0.75y ≥ 6. select all of the other points that are also solutions. use blank paper if it helps with your thinking. (14, 8) (13, 1) (7, 5) (1, 13) (0, 8)
Step1: Sustituir los valores de x e y en la desigualdad.
Para el punto \((14,8)\):
Sustituimos \(x = 14\) y \(y=8\) en \(0.25x + 0.75y\geq6\)
\(0.25\times14+0.75\times8=0.25\times14 + 6=3.5 + 6=9.5\geq6\)
Step2: Para el punto \((13,1)\)
Sustituimos \(x = 13\) y \(y = 1\) en \(0.25x+0.75y\geq6\)
\(0.25\times13+0.75\times1=3.25 + 0.75=4
ot\geq6\)
Step3: Para el punto \((7,5)\)
Sustituimos \(x = 7\) y \(y = 5\) en \(0.25x+0.75y\geq6\)
\(0.25\times7+0.75\times5=1.75+3.75 = 5.5
ot\geq6\)
Step4: Para el punto \((1,13)\)
Sustituimos \(x = 1\) y \(y = 13\) en \(0.25x+0.75y\geq6\)
\(0.25\times1+0.75\times13=0.25 + 9.75=10\geq6\)
Step5: Para el punto \((0,8)\)
Sustituimos \(x = 0\) y \(y = 8\) en \(0.25x+0.75y\geq6\)
\(0.25\times0+0.75\times8=6\geq6\)
