Barbra can walk 3200 meers in 24 minutes what are you asking?
Apply to Row 2 : Row 2 + Row 1
2x + 2y + 3z = 0
y + 4z = -3
2x + 3y + 3z = 5
Apply to Row 3: Row 3 - Row 1
2x + 2y + 3z = 0
y + 4z = -3
y = 5
Apply to Row 3: Row 3 - Row 2
2x + 2y + 3z = 0
y + 4z = -3
-4z = 8
Simplify rows
2x + 2y + 3z = 0
y + 4z = -3
z = -2

Apply to Row 2: Row 2 - 4 Row 3
2x + 2y + 3z = 0
y = 5
z = -2
Apply to Row 1: Row 1 - 3 Row 3
2x + 2y = 6
y = 5
z = -2
Apply to Row 1: Row 1 - 2 Row 2
2x = -4
y = 5
z = 2
Simplify the rows
<u>x = -2</u>
<u>y = 5</u>
<u>z = -2</u>
A function is a repesentashion of time. past or befor so fg means function grafgh is what your exsplaining as in repacentation of wrk)bg, is what happend befor like 1990 no one knows so I would say D
because 4_4 16 4;3 22 is the closest between function and befor g and after becuse 44_16 is 2004 and 20016 do you see know go hard rock star ;-)
