Y=2000*e^{k*t}

2200=2000*e^{k*4}

e^{k}= ( \frac{22}{20} )^{(1/4)}<span>

so,
 y at t=8 is  2000*(</span><span>( \frac{22}{20} )^{(1/4)})^8
 y = 2000(22/20)^2=2000*1.21=</span><span>2420 thats the answer i hope.</span>

What is the value of x, if the equation 2(x + 60) + 2(30) = 200
lawyer [7]
X= -530

This is because:

2(x+60)+2(30)=200
•distribute the 2s into each parentheses
2x+1200+60=200
•combine like-terms
2x+1260=200
•isolate 2x by subtracting 1260 from both sides of the equation
2x=200-1260
•subtract 1260 from 200
2x= -1260
•divide both sides by 2 so you can have x all alone
2x/2= -1260/2
Hence
x= -530
