Proving triangle congruence

given: zlno

zmln

it is given that angle lno is congruent to angle

and angle olnis congruent to angle . we know

that side ln is congruent to side ln because of the

. therefore, because of

y, we can state that triangle lno

is congruent to triangle lnm.

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
