Which graph represents the piecewise-defined function? y=⎪⎪5   if  x< −5−2   if  −5≤x≤61    if  x> 6

See the attached figure

Step-by-step explanation:

The given piecewise function is

Notice that the equality sign appeared at the middle only

so, the middle horizontal line must be blacked on the both sides which is the agree with the upper right figure

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
