Write the standard form of the equation of the parabola with the given focus or directrix and

horsena [70]

Answer:

x = 1/20 y^2

Step-by-step explanation:

This is a rightward opening (sideways ) parabola

Directrix = x = -5

Distance formula form point x,y to directrix and focus are equal:

(x - -5)^2 = (x-5)^2 + y^2

x^2 + 10x + 25 = x^2 - 10x + 25 + y^2

20x = y^2

x = 1/20 y^2

-6 - 3(2x + 4) = 18what’s the answer

Brrunno [24]

Answer:

$x=-6$

Step-by-step explanation:

$-6-3\left(2x+4\right)=18$

Add 6 to both sides:

$-6-3\left(2x+4\right)+6=18+6$

$-3\left(2x+4\right)=24$

Divide both sides by -3:

$\frac{-3\left(2x+4\right)}{-3}=\frac{24}{-3}$

$2x+4=-8$

Subtract 4 from both sides:

$2x+4-4=-8-4$

$2x=-12$

Divide both sides by 2:

$\frac{2x}{2}=\frac{-12}{2}$

$x=-6$
