Suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. write an equation for the water level, l, after d, days.

The equation to represent the rate of receding water level is                     L = 34   .

Step-by-step explanation:

Given as :

The initial level of water in river = 34 feet

The rate of receding water level = 0.5 foot per day

Or, The rate of percentage of receding water level = 50 % per day

Let the level of water after d days = L

Now,

The level of water after d days = initial level of water × (

I.e L = 34 × (

∴  L = 34 ×

Hence The equation to represent the rate of receding water level is                L = 34   . Answer

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
