The time length in hours of a certain airplane flight can be represented by the function f(x) = 0.0025x + 0.75, where x is the number of miles for the flight. The time length of another airplane flight in hours can be represented by the function g(x) = 0.004x + 0.5, where x is the number of miles for the flight. Which function represents the sum of the flight time lengths, h(x) = f(x) + g(x)?
h(x) = –0.029x + 0.25 ,h(x) = 0.0065x – 1.25 ,h(x) = 0.029x – 0.25 ,h(x) = 0.0065x + 1.25

What is the absolute value of -100000000000000?

Given: ad¯¯¯¯¯ is an altitude. prove: ab2+ac2=cb2 right triangle a b c with right angle a. point d lies on side b c and segment a d is drawn. angle a d c is a right angle. drag and drop a reason into each box to correctly complete the two-column proof. statement reason ad¯¯¯¯¯ is an altitude, and ∠bac is a right angle. given ∠adb and ∠adc are right angles. definition of altitude ∠bac≅∠bda ? ∠bac≅∠adc ? ∠b≅∠b ? ∠c≅∠c reflexive property of congruence △abc∼△dba ? △abc∼△dac aa similarity postulate abbd=cbab ? ab2=(cb)(bd) cross multiply and simplify. acdc=cbac polygon similarity postulate ac2=(cb)(dc) cross multiply and simplify. ab2+ac2=ab2+(cb)(dc) addition property of equality ab2+ac2=(cb)(bd)+(cb)(dc) substitution property of equality ab2+ac2=(cb)(bd+dc) ? bd+dc=cb segment addition postulate ab2+ac2=cb2 substitution property of equality
