4. The number of houses in a town has been growing according to the recursive rule Pn=Pn-1 + 30, with initial population P0=200. a. Calculate P1 and P2 b. Find an explicit formula for Pn c. Use your formula to predict the number of houses in 10 years d. When will the number of houses reach 400 houses?

the solution is 12x-6y

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

50x5=$250
