Mark partially drained his pool to clean it. At 1:00 P. M., he started to refill it. At 5:00 P. M., the pool had 10,400 gallons of water. At 9:00 P. M., the pool had 13,800 gallons of water. If filling the pool is modeled by a linear function, how many gallons of water still remained in the pool when he first started to refill it?

A) 6,150
B) 6,500
C) 7,000
D) 7,150

Write each expression in exponential form and find its value. 3 x 3 x 3

Which shows the correct substitution of the values a, b and c from the equation 1=-2x+3x^2+1

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof? statement reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem
