Yes 4 is a value of the solution.

If we plug in 4 to s we get:
4+6 <= 12
10 <= 12

and 10 is in fact less than 12

What is the equation of the quadratic graph with a focus of (−4, seventeen eighths ) and a directrix of y = fifteen eighths

Lunna [17]

Standard form for a parabola:
( x - h )² = 4 p ( y - k )
Vertex: ( h, k ) = ( -4, 2 )
Displacement from vertex to focus:
p = 2/8 = 1/4
( x + 4 )² = 4 · 1/4 ( y - 2 )
y = ( x + 4 )² + 2
or general form:
x² + 8 x - y + 18 = 0

A bicyclist rides 12 miles in 132 minutes. If she continues at this speed, how long will it take her to travel 66 miles?

natima [27]

(132 min)/(12 mi) = (t)/(66 mi)
t = (66 mi)*(132 min)/(12 mi) = 726 min

It will take the bicyclist 726 minutes to travel 66 miles.
