<span>An isosceles triangle has an order 2 rotational symmetry because it has 1 pair of congruent angles.
I hope this helpS!</span>
Answer:
for the first one y would be zero
for the second one c would be -13/3
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.
The answer you want is B, seeing as they go up double
