Responda:
R $ 15.600
Explicação passo a passo:
Deixe a dívida inicial = x = 100%
% pago = 20% = 0,2x
% esquerda =. 100% - 20% =. 80% = 0,8x
35% da dívida restante = 0,35 * 0,8x = 0,28x
Conseqüentemente,
0,28x = 4368
x = 4368 / 0,28
x = R $ 15.600
Logo, o valor inicial da dívida = R $ 15.600
First, we need to find the slope:
m=rise/run OR

m=(2+2)/(-6-2)
m=4/-8
m=-1/2
second we need to find the equation for the line using point-slope form:

y-(-2)=-(1/2)(x-2)


to find "a" we plug in the given y value and solve for x (in this case x=a):




so, a=6 and the point becomes (6,-4)
Answer:
Not a function because the domain 4 repeats.
.28 or 28% chance the randomly selected student is a senior. There are 50 total students in the band, and 14 seniors, so the probability that a senior is randomly selected is 14/50 or .28
