Hello!
Answer:

|2x - 5| = 4
Solve for the negative and positive expressions:
2x - 5 = 4
2x = 9
x = 9/2
------------
-(2x - 5) = 4
-2x + 5 = 4
-2x = -1
x = 1/2.
Therefore, the solutions are x = 1/2 and 9/2.
Answer:
To subtract fractions, find the LCD and then combine.
Exact Form:
1/9
Decimal Form:
0.¯1
For this case we have to:
There are 6 plants per tray.
There are 6 trays for each flat, so for each flat there are
plants.
Saturday day:
Thus, on Saturday they sold 648 plants.
Sunday: 
Thus, on Saturday they sold 756 plants.
Thus, in total
plants were sold.
Answer:
plants were sold.
First, we need to transform the equation into its standard form (x - h)²=4p(y - k).
Using completing the square method:
y = -14x² - 2x - 2
y = -14(x² + 2x/14) - 2
y = -14(x² + 2x/14 + (2/28)²) -2 + (2/28)²
y = -14(x + 1/14)² - 391/196
-1/14(y + 391/196) = (x + 1/14)²
This is a vertical parabola and its focus <span>(h, k + p) is (-1/14, -391/196 + 1/56) = (-1/14, -775/392).
Or (-0.071,-1.977).</span>
Depending on the answer of the problem if it’s negat the sign is so on and so fourth
