Sebastian's friend gives him 4 special-edition baseball cards to start his own collection. Sebastian then buys 6 new baseball cards for his collection every month. If x is the number of months, what is the linear function, f (x), that represents the total number of baseball cards in Sebastian's collection as a function of the number of months?

A: f(x) = 4x
B: f(x) = 6x
C: f(x) = 4x + 6
D: f(x) = 6x + 4

The measurement of one angle of a right triangle is 42° what is the measurement of the third angle? (there is no picture)

What are two numbers that add up to -9 and multiply to -10 best answer gets branliest and 100 extra points

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
