Suppose that tickets for a rock concert cost $5 for the first ticket, $10 for the second ticket, $15 for the third ticket, and so on. If you bought 10 tickets, how much would you pay altogether for all 10 tickets?

275$

Step-by-step explanation:

b

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
