Answer:

g(5) = 5

Step-by-step explanation:

g(5) is really g when x=5 so we have to use the function g(x) when x≥2

g(5) = 2x-5 when x=5

g(5) = 2*5 -5 = 10-5 = 5

25 = 5*5 and 9 = 3*3, which we can exploit to write

$25^x-9^y=(5^2)^x-(3^2)^y=5^{2x}-3^{2y}=(5^x)^2-(3^y)^2$

so that this expression is actually a difference of squares. We can factorize this to get

$(5^x-3^y)(5^x+3^y)=18$

and given that $5^x-3^y=3$ , we divide both sides by this to get

$5^x+3^y=\dfrac{18}3=\boxed{6}$

I = PRT

14,300 = (700)(0.0725)(t)
14,300 = 50.75(t)
14300/50.75 = t
281.77 = t or t = 281.77

hope this helps :)
