7x+8y=-18, 4x-9y=-3 solve the system of equations

25 ! the line of best fit is h = 5a + 86. predict the height at age 16. show your work.

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
