5/7y=3-1/5 what is y?
denis23 [38]
You want y?  One way to get y alone would be to mult. all 3 terms by (7/5):

(7/5)(5/7)y = (7/5)*3 - (7/5)(-1/5).  This simplifies to:

              y = 21/5 * 7/25, or y = 147 / 125.

You could check this using decimal fractions:

                y = 4.20 * 0.28 = 1.176 = 147 / 125.

The cost of an limited edition figurine starts at $255 and it increases in value by 8% each year. What is the growth or decay ra
3241004551 [841]

Answer:

Growth rate = 8% = 0.08

Initial value (Po) = $255

F(t) = Po* e^rt

F(t) = $412.09897

Step-by-step explanation:

Given that:

Initial cost = $255

Rate of increase per year (r) = 8% = 0.08

Growth rate :

Final amount = Initial amount * (1 + rate)^time

Growth rate = 8% = 0.08

Initial value (Po) = $255

Exponential model for the cost :

F(t) = Initial value * e^(rate * time)

F(t) = Po* e^rt

Value after 6 years :

F(t) = Po* e^rt

t = 6

F(t) = 255 * e^(0.08*6)

F(t) = 255 * 1.6160744

F(t) = $412.09897
