She missed the last step of simplifying, she should have gone 1 step further by having it as 1:3

You Didn't simplify the 2 therefore the 2 stayed a 2 if you would have divided 2/2 you wouldn't have made that mistake.

Do you go to k12 btw ?

Find the center, vertices, and foci of the ellipse with equation 3x2 + 8y2 = 24
Sveta_85 [38]

Answer:

The center is at (0,0)

The vertices are at ( ( ±2 sqrt(2),0)

foci are  ( ±sqrt(5),0)

Step-by-step explanation:

3x^2 + 8y^2 = 24

Divide each side by 24

3x^2 /24 + 8y^2/24 = 24/24

x^2/8  + y^2 /3 = 1

The general equation of an ellipse is

(x-h)^2/  a^2  + (y-k)^2 / b^2  = 1

a>b   (h,k) is the center

the coordinates of the vertices are ( ±a,0)

the coordinates of the foci are  ( ±c,0), where  ^c2=a^2−b^ 2

The center is at (0,0)

a = sqrt(8) = 2sqrt(2)

The vertices are at ( ( ±2 sqrt(2),0)

c = 8 - 3 =5

foci are  ( ±sqrt(5),0)

Simplify the difference. (–7x – 5x^4 + 5) – (–7x^4 – 5 – 9x)
sineoko [7]

Answer: 2x^4+2x+10

Step-by-step explanation:

You need to remember the mulplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-

Knowing this, you can distributive the negative sign. Then you get:

(-7x- 5x^4 + 5) - (-7x^4 - 5 - 9x)=-7x- 5x^4 + 5 +7x^4 + 5 + 9x

Now you need to add the like terms. Then:

=2x+2x^4+10

Finally, you can order the polynomial obtained in descending order. Therefore, the answer is:

=2x^4+2x+10
