I received my tickets off an internet site with a discount of 28%. The online sales company then put a 12.5% service fee on my ticket. What percentage of the original price did I get the tickets for?

81%.

Step-by-step explanation:

Let the original price be  x.

With a discount that made it x - 0.28x = 0.72x.

Then we add the service fee of 12.5%:

= 0.72x + 0.125*0.72x

= 0.81x.

So it's 81%.

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)

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
