The number of hours (H) that a candle will burn increases when the length of the candle (L) increases. Write the correct equation for this scenario, and solve for the number of hours when the length is 2.

Length
Hours
15
3

H = .2L; H = .4

H = 1L; H = 2

H = 45 over L; H = 22.5

H = 45 over L; H= 3

so we know "H" gets affected with changes in "L so we can say that "H varies directly to L" or H = (SOME NUMBER HERE) L what's that number? we dunno but we know from the table given, that when x = 3, y = 15 so 15 = (SOME NUMBER HERE) L solve for (SOME NUMBER HERE) to find out what's that number, usually called the CONSTANT OF VARIATION

anonymous · Answer

x = 3, y = 15 so 15 = (SOME NUMBER HERE) 3

anonymous · Answer

it would be the first one because if you just try to solve for the equation of the table, it is the only option that works for this scenario.
