Answer: $500
<u>Step-by-step explanation:</u>
A sells to B at a profit of 10%: 1.10A = B
B sells to C for $577.50 at a profit of 5%: 1.05B = 577.50
Substitute B with 1.10A in the second equation:
1.05(1.10A) = 577.50
1.155A = 577.50
A = 500
Answer:
(5x+3)/2
Step-by-step explanation:
f(x)=(2x-3)/5
f(x)=y
y=(2x-3)/5
interchanging role of x and y
x=(2y-3)/5
5x=2y-3
5x+3=2y
y=(5x+3)/2
the inverse if f(x) = (5x+3)/2

Step-by-step explanation:
LHS= sin 3x/sin x - cos 3x/cosx
Taking LCM,
<u>=</u><u>sin3xcosx- cos3xsinx</u>
sinxcosx
<u>=</u><u>sin(3x-x)</u>
sinxcosx
= <u>2sin2x</u>
2sinxcosx
=<u> </u><u>2sin2x</u><u> </u>
sin2x
=2
= RHS.
Proved.
