Yon buys tickets to a concert for himself and a friend. There is a tax of 6% on the price of the tickets and an additional booki
1 answer:
Well, I assume that both tickets cost the same: let's call it x.
So the tickets cost 106%x (the cost of the ticket plus tax).
The total prize of the tickets will be: 2*106% x+20.
But let's assume that you share it half-half: then each of you pays half of this:
So, this is how much each of you pays: 1.06x+10

Step-by-step explanation:
F(x) = 2x + 5 is a linear graph because the exponent on x is 1. I tell my students that think of graphs having one less turn/corner that the value of the highest exponent. so since 2x has a exponent of 1, 1-1 =0 so it has no turns or its a straight line.
this has a slope of 2 or 2/1 or up 2 and right 1 from the y intercept which is 5
so mark 5 on the y axis and a from there go up 2 and right 1 and make another point. Join these points and you have your graph
and
g(x) = (x-5)/2 is its inverse and is found:
F(x) = 2x + 5 write it this way y = 2x + 5
now swap the x and y x = 2y - 5
solve for y
x = 2y + 5
- 5 -5
x - 5 = 2y
/2 /2
(x-5)/2 = y
it can be written as y = x/2 - 5/2
and graphed the same way as above with a 1/2 slope and -5/2 y intercept
