Sulla retta a, perpendicolare al piano a, sono stati individuati, da parte opposta rispetto al piano,
due punti A e B. Sul piano è stata tracciata la retta
b, passante per il punto di incidenza H, e su di essa
è stato individuato un punto C distante 20 cm da
H. Se il segmento AB è lungo 36 cm ed è diviso dal
7
punto H in due parti tali che AH = di HB, quanto
misurano i segmenti AC e BC? [29 cm; 25 cm]

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
