Drag each tile to the correct location on the table. Each tile can be used more than once, but not all tiles will be used. Lewis

son4ous [18]

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

The fill up of the 5th step is $x = \frac{y-250}{340}$

The fill up of the 6th step is $\frac{8750-250}{340} = 25 = x, \frac{8750-250}{340}= 34 = x$

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 $x = \frac{y-250}{340}$

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.

Cheryl is buying lace for her dance costume. One foot of lace costs 3 dollars. How much does each amount cost?

NemiM [27]

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

$x = 3 \times \frac{3}{4} = \frac{9}{4} = 2.25$

3/4 of a foot will cost $2.25.

Derive the equation of the parabola with a focus at (_5, 5) and a directrix of y = -1.

mars1129 [50]

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

$(x-h)^2=4.a(y-k)$

Now, here

$y=k-a=-1\\\\\text { focus =(h,k+a)}\\\\\text{So,} k+a=5\\\\\text{ by solving these two equation , we get }\\\\a=3\text{ and } k=2$

So equation will be

$(x+5)^2=4\times 3(y-2)\\\\(x+5)^2=12(y-3)\\\\y=\frac{1}{12}(x+5)^2+2$

So, option D is correct .
