Aparabola is represented by the equation y2 = 5x. which equation represents the directrix?
y = –20x = –20y = -5/4x = -5/4

On ed its x = -5/4

Step-by-step explanation:

Step-by-step explanation:

Given equation,

Which is the equation of a parabola along x-axis,

From equation (1),

We know that, the standard form of a parabola along x-axis is,

Where, the directrix is,

x = h-p

By comparing equation (2),

The directrix of the given parabola is,

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
