19/2 = 9.5
(9.5)^2 = 90.25 = 9 + 81.25
x^2 - 19x + 9 = 0
x^2 - 19x + 90.25 - 81.25 = 0
(x - 9.5)^2 = 81.25
x - 9.5 = +/-sr(81.25)
I will let you finish from here
There are linear relationships so long as the power of x is 1 when power of y is 1 / power of x is not 2 and above when power of y is 1. This is assuming you plot the vertical axis as y-axis and the horizontal axis as the x-axis.
So using this concept, the equation with linear relationships are:
1, 3, 4, and 5.
Hope this helps! :)
Answer:

Step-by-step explanation:
Answer:
Would it not be 20?
Step-by-step explanation:
First change them all into either fractions or decimals. Decimals are probably easier though. 1/5 = 0.2; 12/25 = 0.48; 4/5 = 0.8
Order: 0.2, 0.35, 0.48, 0.5, 0.8
Then you change the decimals that you converted back into the fraction form
Answer: 1/5, 0.35, 12/25, 0.5, 4/5
