Answer:
x=-7k/4(9-k) +63/4(9-k)
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Answer:
f^(-1)(x) = 3x/(2-x)
Step-by-step explanation:
f(x) = 2x/(x+3)
f(x)*(x+3)=2x
x(2-f(x))=3f(x)
x=3f(x)/(2-f(x))
f^(-1)(x) = 3x/(2-x)
S = 2 (lw + lh + hw)
S = 2 ((8.5)(11) + (8.5)(2) + (11)(2))
S = 2 (93.5 + 17 + 22)
S = 2 (132.5)
S = 265 sq in
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.p explanation:
