Cross multiply the denominator with 2 to get

3x -1 = 2(x-4)

3x - 1 = 2x - 8

x = -7

A parabola can be drawn given a focus of (8, 6) and a directrix of x=4. Write the equation of the parabola

Orlov [11]

Answer:

The equation of the Parabola

(y - 6 )² = 8 (x -6)

Step-by-step explanation:

Step(i):-

Given directrix x = 4

we know that x = h - a = 4

h -a = 4 ...(i)

Given Focus = ( 8,6)

we know that the Focus of the Parabola

( h + a , k ) = ( 8,6)

comparing h + a = 8 ...(ii)

k = 6

solving (i) and (ii) and adding

h - a + h+ a = 8 +4

2 h = 12

h =6

Put h = 6 in equation (i)

⇒ h - a =4

⇒ 6 - 4 = a

⇒ a = 2

Step(ii):-

The equation of the Parabola ( h,k) = (6 , 6)

( y - k )² = 4 a ( x - h )

(y - 6 )² = 4 (2) (x -6)

(y - 6 )² = 8 (x -6)

Help Help!!!!!!!!!!!!!!!

BabaBlast [244]

Answer:

$\frac{7}{10} y$

Step-by-step explanation:

To add fractions with the same denominator, simply add the numerators:

$\frac{a}{b} + \frac{c}{b} = \frac{a+c}{b}$

So:

$\frac{3}{10} y+\frac{4}{10} y=\frac{7}{10} y$

What is the measure of angle X? Enter your answer as a decimal in the box. Round only your answer to the nearest hundredth. ° tr

klemol [59]

I have attached a diagram of the triangle described.

We can use any of the trigonometric functions to find angle x. Remember, SOH CAH TOA. And since we're finding the angle, we'll need to use an inverse trigonometric function. For this problem, I'll be using the sine function.

sin(x) = 84 / 85

x = sin^-1(84/85)

x = 81.2026 degrees (feel free to round to however many places you need)

Hope this helps!! :)
