Answer:

$820

Step-by-step explanation:

D= Diamond Ring

S= Silver Ring

2D + 4S = 1880

D + S = 880

D = 880 - S

4S + 2(880 - S) = 1880

4S + 1760 - 2S = 1880

2S + 1760 = 1880

2S = 120

S = 60

880 - 60 = 820.

Let f(x) = x - 2 and g(x) = x2 - 7x - 9. Find f(g(-1))

Montano1993 [528]

$f(x)=x-2 \\
g(x)=x^2-7x-9 \\ \\
g(-1)=(-1)^2-7 \times (-1)-9 = 1+7-9=-1 \\
f(g(-1))=f(-1)=-1-2=-3 \\ \\
\boxed{f(g(-1))=-3}$
