Y = 2x/x-7
x = 2y/y-7
xy - 7x = 2y
-7x = 2y - xy
-7x = y(2-x)
y = -7x / 2-x
y = 7x / x-2
f-¹(x) = 7x / x-2
Answer:
On coordinate plane, 2 lines intersect at (negative 1, 4)
Step-by-step explanation:
negative 1 = -1, 4 = 4
therefore this means that this coordinate is also (-1, 4)
The result can be shown in both exact and decimal forms.
Exact Form:
2
3
Decimal Form:
0.

Answer:
Option C - 1/81
Step-by-step explanation:
9^(-2) = 1/(9^2) [ Because a^(-m) = 1/(a^m) ]
so, 1/(9²) = 1/81.
Hope this helps you.
