Answer:
Please check the explanation.
Step-by-step explanation:
- As we know that the values in the table represent a function only if there there is only 1 input for every output.
 
Given the table 1
x              y
-12           2
-10           10
0              -2
5              -6
8               -11
15              -15
From the table, it is clear that for each input there exists a unique output.
i.e.
According to the given table,
y = 2 at x=-12
y = 10 at x=-1
0
y = -1 at x=0
y = -11 at x=8
y = -15 at x=15
From the table, it is clear that for each input x, it has a unique output y.
Hence, table 1 is a function.
Given the table 2
x              y
9            -18
-20           0
-6              1
-17              16
9                17
11              19
This table does not produce a function, because the input x=9 produces two outputs.
i.e.
at x = 9, the y = -18
at x = 9, the y = 17
Therefore, the table 2 does not represent a function.
 
        
             
        
        
        
Answer:
Yes, this is a right triangle
Step-by-step explanation:
Plug the values into the pythagorean thm. 
1.5^2 + 2^2 = 2.5^2
2.25+4=6.25
6.25=6.25
 
        
             
        
        
        
Answer:
x = 5
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles in the triangle and equate to 180, that is
10x - 4 + 8x + 3 + 91 = 180
18x + 90 = 180 ( subtract 90 from both sides )
18x = 90 ( divide both sides by 18 )
x = 5
