Answer:
Madeline: y=1x+9
Issac: y=2x+1
x=8, y=17
Step-by-step explanation:
<u><em>Solving for X:</em></u>
<u>Multiply Issac's by -1:</u>
y= 1x+ 9
-y=-2x-1
<u>Combine:</u>
0=-x+8
<u>Add x to both sides:</u>
<em><u>x=8</u></em>
<em><u>Solving for Y:</u></em>
<em>Since we already have x, we only need to input the x value into one of the formulas:</em>
y=1(8)+9
<u>Simplify parenthesis with multiplication:</u>
y=8+9
<u>Add:</u>
<u><em>y=17</em></u>
If you feel unsure, check your work with both equations:
(17)=2(8)+1
17=16+1
17=17=Good
(17)=1(8)+9
17=8+9
17=17=Good
Please give a brainliest and a thx ;)
I hope this helps u :)

Answer:
Table 3 has a greater y intercept
Step-by-step explanation:
See attachment (1) & (2) for graph and tables
First, we have to determine the y intercept of the graph
The y intercept of any graph or table is the corresponding value of a point where 
In the attached graph.
when 
So:

Next, we determine the y intercept of each table.
Recall that: The y intercept of any graph or table is the corresponding value of a point where 
For table 1:

For table 2:

For table 3:

By comparison, the y intercepts of tables (1) & (2) are less than the y intercept of the graph because: 3 and 2 are less than 4
However, the y intercept of table 3 is greater than the y intercept of the graph because 5 is greater than 4.
<em>Hence, table 3 has a greater y intercept</em>
Since the sum of the angles of a triangle = 180°
Then (2x)º + (x + 60)º + (3x)º = 180°
(6x)° + 60° = 180°
(6x)° = 180° - 60°
x = 120° ÷ 6
∴ x = 20
