There are different ways you can write these numbers all you do is go by what the number says and think about it.

EX1) 12-5=7

Solve for v: -v+1=1 + 8v
AfilCa [17]

Answer: v=0

Step-by-step explanation:

Because....

Step 1: Simplify both sides of the equation.

−v+ 1= 8v + 1

Step 2: Subtract 8v from both sides.

−v+1 − 8v = 8v+1 − 8v

−9v + 1 = 1

Step 3: Subtract 1 from both sides.

−9v + 1 −1 = 1−1

−9v=0

Step 4: Divide both sides by -9.

\frac{-9v}{-9} = \frac{0}{-9}

v=0

Therefor, the answer is v = 0

Part 3: Write the equation of and graph an ellipse.
tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

The center is halfway between vertices, at (4, -6).

It is also halfway between foci.

:::::

The vertices are vertically aligned, so the parabola is vertical.

General equation for a vertical ellipse:

 (y-k)²/a² + (x-h)²/b² = 1

with

 center (h,k)

 vertices (h,k±a)

 co-vertices (h±b,k)

 foci (h,k±c), c² = a²-b²

Apply your data and solve for h, k, a, and b.

center (h,k) = (4, -6)

h = 4

k = -6

vertices (4,-6±a) = (4,-6±9)

a = 9

foci (4,-6±c) = (4,-6±5√2)

b² = a² - c² = 9² - (5√2)² = 31

b = √31

The equation becomes

 (y+6)²/81 + (x-4)²/31 = 1

:::::

length of major axis = 2a = 18

length of minor axis = 2b = 2√31
