Which graph represents the piecewise-defined function? y=⎧⎩⎨⎪⎪5   if  x≤−20   if  x=3−1    if  x> 3

3

step-by-step explanation:

i think it will be 4feet long of what i comprehend

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.

the answer is  

c.

14,469 cubic feet

i know this one is right
