2 * 3 the X Factor what is the problem so you exit out and you get 2-3 and 2-3 is indicated so you subtracted by one and you get 0.58
it all depends on the equation really.
i prefer to use elimination when i can.
hope this helps! -Jentri
5 cans need to be bought. There are three servings in each can so you divide 15 by 3.
Let's solve ~
Equation of directrix is : y = 1, so we can say that it's a parabola of form : -
- h = x - coordinate of focus = -4
- k = y - coordinate of focus = 5
- a = half the perpendicular distance between directrix and focus = 1/2(5 - 1) = 1/2(4) = 2
and since the focus is above the directrix, it's a parabola with upward opening.
