Answer:

the two numbers are 19 and 32

Step-by-step explanation:

<em>let's call the numbers x and y.</em>

<em>write out the equations</em>

x + y = 51

x - y = 13

<em>simplify the second equation</em>

x = 13 + y

<em>substitute into the first equation and simplify</em>

(13 + y) + y = 51

13 + 2y = 51

2y = 51 - 13

2y = 38

y = 19

<em>substitute y for 19 in the second equation</em>

x = 13 + y

x = 13 + 19

x = 32

Part A: it is linear because it is not curving and it consists of straight lines.

Part B: in side A it is increasing because it has a positive slope. In side b it is constant because the slope is 0 since it is straight. Finally, side C is decreasing because the slope is negative.

Part C: during side A the ant is crawling out of the hole in 2 seconds. After that, the ant stops for 2 more seconds as shown in side B. Then, he crawls back into the hole as shown by the decrease in distance due to the slope.

Hope this helps!!!
