Point R is midpoint of segment GL. GR = 6x - 3 RL = 2x + 9 GR =? RL =? GL =?

1 answer:

4 0

Because R is the midpoint, both segments are equal to each other. set sides equal to each other to solve for R.

6x-3 = 2x+9 x=3

plug x value into each equation

GR= 15

RL= 15

GL= 30

Answer: 19 years

Step-by-step explanation:

Given

Amount invested $\$400$

Rate of interest $R=6\%$

after 1-year amount becomes

$A=400\left (1+6\%\right)\\A=400\left (1+0.06\right)\\A=400\times 1.06\\A=\$424$

After n years it is

$A=400\left (1.06\right)^n$

Sum accumulated is $\$1200$

$\Rightarrow 1200=400\left(1.06\right)^n\\\Rightarrow 3=\left(1.06\right)^n\\\text{Taking log both sides}\\\Rightarrow n=\dfrac{\ln 3}{\ln 1.06}\\\\\Rightarrow n=18.85\approx 19\ \text{years}$
