You are correct for all of them,
Precision goes up as you have more decimals. It gives you a more accurate measurement regardless of what it is measuring.
A line graph measures two variables, the X and the Y, and how they change based off of one another
And an educated guess would usually based on previous trends or results
Substitution:
2x + (6(1/2x - 6)) = 19
2x + 3x - 36 = 19
5x - 36 = 19
+ 36
5x = 55
÷ 5
x = 11
y = (1/2 × 11) - 6
y = 5.5 - 6
y = -0.5
Elimination:
y = 1/2x - 6
- y
0 = 1/2x - 6 - y
+ 6
1/2x - y = 6
3x - 6y = 36
2x + 6y = 19
(add)
5x = 55
÷ 5
x = 11
y = (1/2 × 11) - 6
y = 5.5 - 6
y = -0.5
I hope this helps! Let me know if you need me to explain why I did some things :)
Somebody? I think you can find someone like that in your school... nice profile picture.
