Answer:
Perimeter =28 units.
Area = 45 unit^2.
Step-by-step explanation:
The length of first side (joining first 2 points) = 5 - (-4) = 9 (as y coordinates are both -5)
The line joining the 2nd and third points = 0 - (-5) = 5
The line joining the 3rd and 4th points = 5 - (-4) = 9.
The line joining the first and 4th points = 0 - (-5) = 5
So the perimeter = 2(5) + 2(9)
= 28 units.
Area = 5*9 = 45 unit^2.
The equation t = 10.5(c + a) represents the total money earned by the company from the sale of tickets
<u>Solution:</u>
Given that,
Ticket charged for people of all age groups = $ 10.50 per ticket
Let "c" represents the total number of children who bought tickets
Let "a" represents the total number of adults who bought tickets
Now, let the total money collect be represented by "t"
Number of people bought tickets = number of children bought tickets + number of adults bought tickets
<em><u>Now the total money earned by company is given as:</u></em>
Total money earned = cost per ticket x number of people bought tickets
Total money collected = cost per ticket x (number of children bought tickets + number of adults bought tickets)
Substituting the known values we get,

t = 10.5(c + a)
Hence, the required equation is t = 10.5(c + a)

I can’t see the coordinates to help you do this but I’m going to try explaining it to you. in the first example on your sheet you can see 2 of the points of the triangle are 1 above the x axis. to reflect it over the x axis you’d go 1 below the x axis. To reflect over the y axis you do the same thing. Looking at the point (1,1) I think still on the triangle one. You see it’s 1 away from the y axis so you’d do the same thing as in the x. it’d be (-1,1).
