Answer:
Step-by-step explanation:
Given

comparing it with standard equation 
so 4a=1

so Focus of parabola is (0,0)
directrix
y=-a
here 
20x^2+50 = -40x^2+110x [ Taking x as the unknown positive integer ]
An ordered pair is written like this, ( x, y ). In this case x = 0 and y = -3. On a graph the vertical line is the y-axis and the horizontal line is the x-axis. The origin is point ( 0, 0 ). To the left of the origin on the x-axis is the negative number line and to the right is the positive number line. On the y-axis, south of the origin is the negative number line and north is the positive number line. When you plot a point on a graph you do x first, so if x equals 1, you would move one right, -1, one left. IF y were to equal 2 then from the place where you are on the x-axis, 1, you would move two up, -2, two down. In this case x = 0 so you would stay at the origin, and y = -3 so you would move 3 down. So ( 0, -3 ) would lie negative y-axis. The answer is D.
Answer:
2(17-27x)
Step-by-step explanation:
Since the question was incomplete this is the only answer I have for you.
If you were looking for the answer of X I would need a answer for the equation
Anyways... you want to factor out 2 from the expression since there are two numbers
Once you factored out the two (divide each number by 2) you'll get:
2(17-27x)
