The equation you use to find the average rate of change, or slope, is
Vertical angles are congruent due to the fact that they intersect. If they did not, they would in fact be parallel. (last section)
A)15000 x (9 : 100) x 3 = 4050
B) 15000 + 4050 = 19050
I hope it is correct ❤️
Answer:
Let the Dulcina's collection be 'x'
Let the Tremaine collection be 'x-39'
x + x - 39 =129
2x = 129 +39
2x = 168
x = 168/2
x = 84
Dulcina's collection = x = 84
Tremaine's collection = x - 39 = 84 - 39 = 45
