Graph linear system and estimate the solution y=5x + 2 y=3x

NeTakaya

Y = 5x + 2
y = 3x

5x + 2 = 3x
- 5x - 5x
      2 = -2x
   -2 - 2
       -1 = x
y = 3x
y = 3(-1)
y = -3
(x, y) = (-1, -3)

After the closing of the mill, the town of Sawyerville experienced a decline in its population.

vfiekz [6]

Step-by-step explanation:

P(t) = 12,000 (2)^(-t/15)

9,000 = 12,000 (2)^(-t/15)

0.75 = 2^(-t/15)

ln(0.75) = ln(2^(-t/15))

ln(0.75) = (-t/15) ln(2)

-15 ln(0.75) / ln(2) = t

t = 6.23

One pump can fill a swimming pool in 72 hours. A second pump can fill the same pool in 60 hours. If

Studentka2010 [4]

I’m not sure but i think 66 hours because both pumps must fill half of the pool which would split the timing for each which would make pump 1 take 36 hours to fill half and pump two take 30 hours to fill the rest. when you add these hours it equals 66. i hope i helped :)
