Elenna [48]
Let the original cost of laptop=x
Savings=20% = 20/100
Saved amount = $140
Original cost = saved amount * 1/savings
x = 140* 100/20
x = $7000

1. We can conclude that the result of the division is x-13 with a remainder of 4x-9, or in other notation: x-13+ \frac{4x-9}{x^2+3}. Check the steps in the first image.

3. We can conclude that the result of the division is x^{2} +6x+3 with a remainder of 2, or in other notation: x^{2}+6x+3+ \frac{2}{x-1}. Check the steps in the firts image.

5. We can conclude that the result of the division is x+1 with a remainder of 5, or in other notation: x+1+ \frac{5}{x-4}. Check the steps in the first image.

7. To check if x+4 is a factor of x^{3}+3x^{2}-10x-24, we are going to perform long division. If the result of the long division has no remainder, x+4 is a factor of x^{3}+3x^{2}-10x-24.
Since the result of the long division has no remainder, we can conclude that x+4 is a factor of x^{3}+3x^{2}-10x-24. Check the steps in the second image.

9. To check if x-3 is a factor of x^{3}+3x^{2}-10x-24, we are going to perform long division. If the result of the long division has no remainder, x-4 is a factor of x^{3}+3x^{2}-10x-24.
Since the result of the long division has no remainder, we can conclude that x-4 is a factor of x^{3}+3x^{2}-10x-24. Check the steps in the third image.

10. We can conclude that the result of the synthetic division is -2x^{2}+9x+5. Check the steps in the fourth image.

A parabola can be drawn given a focus of (-5, -4)(−5,−4) and a directrix of y=-6y=−6. Write the equation of the parabola in any
lord [1]

Answer:

\displaystyle \large{y=\dfrac{x^2}{4} + \dfrac{5x}{2} + \dfrac{5}{4}}

Step-by-step explanation:

Given:

  • Focus = (-5,-4)
  • Directrix = -6

To find:

  • Parabola Equation

Locus of Parabola (Upward/Downward)

\displaystyle \large{\sqrt{(x-a)^2+(y-b)^2} = |y-c|}

Where:

  • (a,b) = focus
  • c = directrix

Hence:

\displaystyle \large{\sqrt{(x+5)^2+(y+4)^2}=|y+6|}

Cancel square root by squaring both sides as we get:

\displaystyle \large{(x+5)^2+(y+4)^2=(y+6)^2}

Solve for y-term:

\displaystyle \large{(x+5)^2=(y+6)^2-(y+4)^2}\\\displaystyle \large{x^2+10x+25=y^2+12y+36-y^2-8y-16}\\\displaystyle \large{x^2+10x+25=4y+20}\\\displaystyle \large{x^2+10x+5=4y}\\\displaystyle \large{y=\dfrac{x^2}{4} + \dfrac{5x}{2} + \dfrac{5}{4}}

Which transformation will move polygon ABCD completely into one quadrant?
velikii [3]

Answer:

A) up 5 units

Step-by-step explanation:

Given

See attachment for grid

Required

Which places ABCD in a quadrant

<u>Considering vertical movements</u>

From the x-axis, the distance between each point and the line of the x-axis is (the y coordinates):

A = -4

B =3

C = 7

D = -2

Considering the highest magnitudes in the positive and negative column, we have:

A = -4 and C = 7

A = -4 means that a upward movement by (4 + 1) units will move ABCD completely in a quadrant;

4 + 1 = 5

<em>Hence, 5 units upward -- This represents option (a)</em>

C = 7 means that a downward movement by (7 + 1) units will move ABCD completely in a quadrant

7 + 1 = 8

<em>Hence, 8 units downward</em>

<em />

<u>Consider horizontal movements</u>

From the y-axis, the distance between each point and the line of the x-axis is (the x coordinates):

A = -8

B = -6

C = -3

D =-2

Considering the highest magnitudes in the positive and negative column, we have:

A = -8

A = -8 means that a left movement by (8 + 1) units will move ABCD completely in a quadrant;

8 +1 = 9

<em>Hence, 9 units upward </em>

<em />

<em>(a) answers the question</em>
