The roots are 1, 1 again, and -5
Answer:
First Option
Step-by-step explanation:
First, we will find the equation for the total cost of the tickets.
Given x = Cost of 1 adult ticket
y = Cost of 1 Child ticket
Total Cost of tickets at $40:
2x + 4y = 40
To find which graph represent the cost of the tickets,
we can substitute x = 0 to find y and vice-versa.
If x = 0 ,
So when x = 0 , y = 10 which gives the coordinates (0,10).
Now if y = 0,
So when y = 0 , x = 20 which gives the coordinates (20,0)
This shows that this particular line passes through these 2 points and therefore the answer is the first option.
Answer:110k per minute
Step-by-step explanation: 30 seconds is half of a minute, so you multiply 30 seconds by 2 to get the rate per minute, 110k.

Equation
------------------------------------------------------------
3(x + 2) = 12
------------------------------------------------------------
Open the bracket
------------------------------------------------------------
3x + 6 = 12
------------------------------------------------------------
Subtract 6 from both sides
------------------------------------------------------------
3x + 6 - 6 = 12 - 6
3x = 6
------------------------------------------------------------
Divide by 3 on both sides
------------------------------------------------------------
3x ÷ 3 = 6 ÷ 3
x = 2
------------------------------------------------------------
Answer: x = 2 (Answer A)
