Answer:
17. 20
18. 50
19. 50
20. 70
21. 110
22. 160
Step-by-step explanation:
I did this assignment already :)
900 because 9 is greater than 5 so it rounds to my answer.
You can give me the choices, are there even any?
Solution:
Since the graph passes through the given points, (7, 20) & (-2, 11) are the solutions of the given equation <em>y = x + ?</em>.
⇒<em>(x, y)</em> = (7, 20); (-2, 11)
Substituting the variables with (7, 20),
20 = 7 + <em>?</em>
20 - 7 = <em>?</em>
<em>?</em> = 13
Similarly,
11 = -2 + <em>?</em>
<em>?</em> = 13
∴ <em>y</em> = 13
