If you're twice a fast then... we'll divide 6750 by 3, that equals 2250.
<span>Equation.. y=your friend and you would be 2y cuz you're twice as fast.
</span>y+2y=6750,
3y=6750
y=2250
Your friend stuffed 2250 in 4.5 hrs.
You (twice as fast) stuffed 4500 in 4.5 hrs.
Working alone, your friend can stuff 2250 in 4.5hrs so it would take 13.5hrs to stuff 6750.
Equation.. (6750/2250) x 4.5hrs = 13.5hrs
You can 4500 in 4.5hrs so it would take you 6.75 hrs to stuff 6750.
Equation.. (6750/4500) x 4.5hrs = 6.75 hrs.
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
Hopefully this helps:) Please mark me brainiest:)
