Answer:
B. (1, 2)
Step-by-step explanation:
In a function, each value used in as an x-coordinate can be used only once.
Values already used as x-coordinates: -3, 8, 0, -5
The answer cannot have -3, 8, 0, or 5 as an x-coordinate.
The only choice without one of those four values as an x-coordinate is (1, 2).
Answer: B. (1, 2)
The value of the directrix is -5/4.
According to the statement
we have given that the equation of parabola is y2 = 5x. And we have to find that the which equation represents the directrix.
We know that the general equation of parabola is
(y - k)2 = 4a(x - h) -(1)
and given parabola equation is
y2 = 5x. -(2)
After comparing the both equations we get k=0 and h=0
And the formula to find the directrix is
x = h - a
Substitute the values of h and a in it then
x = 0-5/4
x = -5/4.
Here the directrix is -5/4.
So, The value of the directrix is -5/4.

Answer:
3x-2
Step-by-step explanation:
JK =JL+LM
5x-8=JL +(2x -6)
JL = 5x-8 -2x+6
JL = 3x-2
