The answer would be A, it has no solution
A. 168 cm.
V=lwh
4 x 7 x 6 = 168 .
ax+by=20
a represents how many first items you bought
x represents the cost of the first item
b represents how many second items you bought
y represents the cost of the second item
The graph of the inverse secant function would possibly be the third one I think.
Slope=rise/run
this one
slope=increase in money/increase in time
from 412 to 549 that is 137, increase 137
from 1990 to 1999, that is 9 years, increase 9 years
slope=$/t
slope=137/9
slope=15 and 2/9
