Answer:

  26. B(t) = 500·1.075^t; B(6) ≈ $772

  27. G(t) = 70·0.72^t; G(3) ≈ 26 g

Step-by-step explanation:

The equation with the plus sign is used when the value is increasing. The minus sign is used when the value is decreasing. The 'a' in each equation is the initial value.

__

26. B(t) = 500·1.075^t

  B(6) = 771.65

The balance after 6 years is about $772.

__

27. G(t) = 70·0.72^t

  G(3) = 26.127

About 26 grams are left after 3 days.

Slope of (-20,9) (14,9)
skelet666 [1.2K]
Y2-y1/x2-x1 is slope so

9-9/14-(-20) so you get 0/34 which means there is no slope since they have the same y (the equation would be y=0x+9 therefore y=9)
Which makes sense since the equation is a straight line
