The directrix of a parabola<span> is the horizontal line found by subtracting p p from the y-coordinate k k of the vertex if the </span>parabola<span> opens up or down. Substitute the known values of p p and k k into the formula and simplify. Use the </span>properties<span> of the </span>parabola<span> to analyze and graph the </span>parabola<span>.</span>
Take any 2 points from the given line and use the rule to find slope
(3,0) (0,-1)
Slope= y2-y1/x2-x1
Slope= -1-0/0-3= -1/-3 = 1/3
Final answer :
Slope = 1/3
So it’s the first option :)
15 people = 9 lbs pasta
1 people = 9/15 lbs. pasta
So, for 76 people = 9/15 * 76 = 45.6 lbs pasta
First we assume that this is equal to zero
so what we notice is this is a sum of 2 perfect cube
recall that
a^3+b^3=(a+b)(a^2-ab+b^2)
125x^3+343=
(5x)³+(7)³=(5x+7)(25x²-35x+49)
now solve the part in second parenthasees because we can see that the first parenthasees (5x+7) is going to have a real root
remember quadratic formula
for ax^2+bx+c=0
x=

a=25
b=-35
c=49
