The fill up for the 3rd step is y - 250 = 340x.
- The fill up of the 5th step is

- The fill up of the 6th step is

- The justification for the 2nd step is subtraction PE.
- The justification for the 4th step is division PE.
<h3>What is the
simplification about?</h3>
Note that:
y-250 = 250 + 340 x - 250
y = 250 + 340x.
Make x the subject of the formula:
y - 250 = 340x.
then y-250/340 = x
Then 
The justification for the second step is subtraction property of equality because it undergoes subtraction and the collection of like terms and then subtracting them from one another as shown below:
y-250 = 250 + 340 x - 250
y= 250 + 340x - 250 + 250
Note that (-250 + 250) = 0
y = 250 + 340x.
Lastly, The fill up of the 6th step is substitution of the amount of money saved and then simplifying it.

Answer:
3/4 of a foot will cost $2.25.
Step-by-step explanation:
This question is solved by rule of three, due to proportions.
One foot of lace costs 3 dollars. How much is 3/4 of a foot going to cost?
1 foot - 3 dollars
3/4 foot - x dollars

So
3/4 of a foot will cost $2.25.
Answer: Option D is correct.
Step-by-step explanation:
Since we have given that
focus = (-5,5)
and a directrix y= -1
Since, equation of parabola in this case will be

Now, here

So equation will be
So, option D is correct .
