Answer:
yes
Step-by-step explanation:
To determine if the point lies on the line substitute the coordinates into the left side of the equation and if equal to the right side then the point lies on the line
- 3 + (4 × 4) = - 3 + 16 = 13 = right side
Hence (- 3, 4) lies on the line x + 4y = 13
10 in each do 10 times 3 then subtract total
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
