Phoenix [80]3 years ago

Pilar started with 80 and adds 10 each week.

y= 10x + 80 (ten seashells • weeks + 80 she started with)

Marisol started with 0 and adds 20 each week.

y = 20x (no need to add + 0 because she started with nothing)

Inequality:

y = 10x + 80 < y = 20x

Weeks:

I would reccomend just plugging in numbers (for example if I put in 5 I would determine if it was too high or low then go to the next number.)

I plugged it into an online graph so I can’t show my work but the answer is 8 weeks.

Find the coordinates of point P
Drupady [299]
Here is the formula for finding a partitioning point:
x=x1+k(x2-x1), y=y1+k(y2-y1)
k is the ratio of the segment from the beginning point to the partitioning : the whole segment. In this case, k=AP:AB=5/16
so x=1+(5/16)*(-2-1)=1/16
y=6+(5/16)(-3-6)=51/16
so the answer is (-1/16, 51/16)

Please double check my calculation by yourself.

refer to this website for the formula and how to find k:

"This ratio is called k, and is determined by writing the numerator over the sum of the numerator and the denominator of the original ratio."
