Answer:
Mary's brother practiced 4 times as long.
Step-by-step explanation:
Mary practiced violin for 2 hours.
Her brother practiced trombone t times as long or 8 hours.
t times of 2 hours = 2t hours

t = 4
Hence, Mary's brother practiced 4 times as long as Mary.

Option 1 is the correct answer. The open circle means that the end value (78) is not included in the solution. That is why the inequality statement says 78 > x.
Answer:
Step-by-step explanation:
g(x) = 1/4(x - 4) (x - 8)
g(x) = 1/4(x^2 - 8x - 4x + 32)
g(x) = 1/4(x^2 - 12x + 32)
g(x) = 1/4x^2 - 3x + 8)
