Initially a pool contains 350 gallons of water. a hose is placed in the pool and the water is turned on. the hose adds 5.2 gallons of water per minute. model the total amount, v, of water in the pool for x, the number of minutes the hose has been on.
a
v(x) = 5.2x
b
v(x) = 350x - 5.2
c
v(x) = 350x + 5.2
d
v(x) = 5.2x + 350

Nina has prepared the following two-column proof below. she is given that ∠oln ≅ ∠lno and she is trying to prove that ol ≅ on. triangle oln, where angle oln is congruent to angle lno step statement reason 1 ∠oln ≅ ∠lno given 2 draw oe as a perpendicular bisector to ln by construction 3 ∠leo ≅ ∠neo transitive property of equality 4 m∠leo = 90° definition of a perpendicular bisector 5 m∠neo = 90° definition of a perpendicular bisector 6 le ≅ en definition of a perpendicular bisector 7 δole ≅ δone side-angle-side (sas) postulate 8 ol ≅ on cpctc nina made two errors in the proof. identify and correct the errors.
