M is equal to the value m
There are three elements in that set.
Answer:
Step-by-step explanation:
The directrix of the parabola is the horizontal line with the eqaution 
The focus of the parabola is at point (-4,10), than the axis of symmetry of the parabola is the perpendicular line to the directrix passing through the focus. Its equation is 
The distance between the directrix and the focus is 
so 
and the vertex is at point 
Parabola goes in positive y-direction, hence its equation is
where 
is the vertex, so the equation of this parabola is
Answer:
on the number line make an open circle at 80 (am open circle is this: ○) and connect that to an arrow that points back to 0 and the negative numbers. It doesn't matter how far back as long as you make it an arrow
