151 * 5 = 755
23,000 - 755 = 22,245
It'll be worth $22,245 in 5 years.
3^5) (x + 2)^(3/2) + 3 = 27
<span>(x + 2)^(3/2) = 24 / 243 </span>
<span>x + 2 = [ 24 / 243 ]^(2/3) </span>
<span>x + 2 = [ 8 / 81 ]^(2/3) </span>
<span>x = [ 4 / 81^(2/3) ] - 2 =-1.786
the answer is x=-1.786</span>
Direct variation is y=kx and inverse variation is y=k/x, in this case:
y=-16/x
So this is an inverse variation with a constant of -16
