Write an equation of the parabola shown.
zzz [600]

Step-by-step explanation:

General equation of a parabola parallel to the x-axis: (y - k)^2 = 4p(x - h).

Vertex = (h, k) = (0, 0)

Directrix: x = h - p = -2.

Since h and k are 0, p must be 2.

Therefore the equation is y^2 = 8x.

Errol's bike ride from home to school can be modeled by the equation d(t) = -4t+2, where d(t) is
8_murik_8 [283]

Answer:

Option (2).It has a vertical translation by 2 units in the positive direction.

Step-by-step explanation:

Given question is not complete: find the  complete question with attachment

Errol's bike ride can be modeled by the equation,

d(t)=-\frac{1}{4}t+2

Slope of the given equation = -\frac{1}{4} which shows the rate of change of distance from Errol's house

Y-intercept = 2, shows the distance of the school from Errol's house

Let the equation that represents the distance of Daniel's home from the school is,

y = mt + b

Since speed of Daniel is equal to the speed of Errol, slopes of both the equations will be same.

Since y-intercept 'b' represents the distance from his home, b = 4

Now the equation will be,

d(t)=-\frac{1}{4}t+4

Therefore, the graph representing the Daniel's equation will have a vertical translation by 2 units in the positive direction.

Hello from MrBillDoesMath!

Answer:   x =  10 for 4x - 8 = 32

               x = -5  for 2(x-5) = -20

Discussion:

------------------------------

4x - 8 = 32    (*)

Add 8 to both sides:

4x - 8 + 8 = 32 + 8 =>

4x = 40 =>

x = 10


-----------------------------------------------

2(x-5) = 2x - 2(5)  =>

2x - 10 = -20 (**)

Add 10 to each side of (**):


2x - 10 + 10 = -20 + 10 =>

2x = -10

x = -5




Thank you,

MrB

A word problem/story with 12x/-2 = 48 as an equation!!
Svetlanka [38]

Answer:

<u><em>Answer is below</em></u>

Step-by-step explanation:

<u><em>Multiply both sides by -2.</em></u>

<u><em /></u>12x/-2=48\\(12x-2)(-2)=(48)(-2)\\12x=-96

<em><u>Divide both sides by 12.</u></em>

<em><u /></em>\frac{12x}{12}=\frac{-96}{12}\\ x=-8
