Answer: D. quadratic
Step-by-step explanation:
Answer: each boy had $2.5 left after buying his ticket.
Step-by-step explanation:
Miguel and three of his friends went to the movies. They originally had a total of $40. If each boy had the same amount of money, it means that the amount that each boy( 4 boys in total) has is 40/4 = $10
Let x represent the amount of money that each boy had left after buying his ticket. If each boy spent $7.50 on a ticket, then the equation becomes
x + 7.5 = 10
Subtracting 7.5 from the left hand side and the right hand side of the equation, it becomes
x = 10 - 7.5 = 2.5
x^3 + 64 = 0
Subtract both sides by 64:
x^3 = -64
x = -4
