Answer:
Two ways you can group them is:
(4+7)+2
4+(7+2)
They will both give you the same answer of 13.
(4+7)+2 4+(7+2)
11+2= 13 4+9= 13
Answer:
Loaves of bread: b can't be a negative value, then the first table doesn't include viable solutions.
The number of loaves of bread must be a whole number, then the second table doesn't include viable solutions.
c=3.5b
if b=0→c=3.5(0)→c=0
If b=3→c=3.5(3)→c=10.5
If b=6→c=3.5(6)→c=21
If b=9→c=3.5(9)→c=31.5
The third table includes viable solutions

If we set the vertex at (0,0) then the curve goes through (30,30)
<span>y = 1/30 x^2 </span>
<span>x^2 = 30y </span>
<span>Since the parabola x^2 = 4py has its focus at y=p, 4p=30 and the mic should be 15/2 inches up from the vertex.</span>
To the nearest whole number it would be 35
