Mr. Frankel bought 9 tickets to a puppet show and spent $65.
He bought a combination of child tickets for $4 each and adult tickets for
$7 each. Which system of equations below will determine the number of
adult tickets, a, and the number of child tickets, c, he bought?

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)

the first one, all those points on the line just make a strait line.

hope it's you

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
