Your total at a store is $50. If you decide to use a coupon for 10% off, which expression shows how much you would pay?
a) 50 - 10
b) 90(50)
c) 50(90)
d) .10(90)

im gonna say d not sure, 10% is 5 dollars off tho

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
