Point L is on line segment KM. Given LM = 3x + 3,

iris [78.8K]

Answer:

KM = 4

Step-by-step explanation:

$LM = 3x + 3$

$KM = 5x + 4$

$KL = 5x + 1$

$KL + LM = KM$ (segment addition postulate)

$(5x + 1) + (3x + 3) = 5x + 4$ (substitution)

Solve for x

$5x + 1 + 3x + 3 = 5x + 4$

Combine like terms

$8x + 4 = 5x + 4$

$8x + 4 - 4 = 5x + 4 - 4$

$8x = 5x + 0$

$8x - 5x = 0$

$3x = 0$

$x = 0$

$KM = 5x + 4$

Plug in the value of x

$KM = 5(0) + 4$

$KM = 0 + 4 = 4$

The population of Knoxville is 500,000 and is increasing at the rate of 3.75% each year. Approximately when will the population

pochemuha

Dp/dt = .0375 people/year

ln p = .0375 t + c 

p = c e^(.0375 t) 
when t = 0, p = 500,000 
so 
p = 500,000 e^(.0375 t) 

so 
2 = 1,000,000/500,000 = e^(.0375 t) 
ln 2 = .0375 t 

t = 18.5 years
