Step-by-step explanation:
An = A + (n - 1)d
We have An = 81, d = -3 and n = 18.
Hence A = An - (n - 1)d = 81 - (17)(-3) = 132.
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.

The coordinate of the point C from the given triangle ABC after translation is C' = (4, -2)
<h3>Translation of coordinates</h3>
A triangle is a 2D figure with 3 sides and angles. Given the coordinate C points of the triangle;
C = (-2, -3)
If these coordinate point is translated 6 units to the right and 1 units up, the resulting coordinate will be at:
C' = (-2 + 6, -3 + 1)
C' = (4, -2)
Hence the coordinate of the point C from the given triangle ABC after translation is C' = (4, -2)
