the cost to go bowling is a function in terms of the number of games bowled. the cost to bowl 2 games with a shoe rental is $16.50. the cost to bowl 4 games with a shoe rental is $28.50. what is the cost of renting shoes?

x = cost of games bowled = $6

y = cost of shoe rental = $4.50

Step-by-step explanation:

Let

x = cost of games bowled

y = cost of shoe rental

2x + y = 16.50 (1)

4x + y = 28.50 (2)

Subtract (1) from (2) to eliminate y

4x - 2x = 28.50 - 16.50

2x = 12

x = 12/2

x = 6

Substitute x = 6 into (1)

2x + y = 16.50 (1)

2(6) + y = 16.50

12 + y = 16.50

y = 16.50 - 12

y = 4.50

x = cost of games bowled = $6

y = cost of shoe rental = $4.50

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)

60 for the first and 130 for the second
