Step 1: plug in the numbers. 7(6)-4
Step 2 multiply 7x6 42-4
X/6.2=-2.1
multiply both sides by 6.2
x=-13.02
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
Answer:
X=1 - y/2
Step-by-step explanation:
2x = 2 - y
divide both sides by 2
x = 1 - y/2
