So, bike=b and accessories=a.
b+a=320
Since the bike is worth 7 times more than the accessories, the b would turn into 7a (because 7 times the cost of accessories is the cost of the bike).
The equation would now turn into 7a+a=320.
Solve for a.
7a+a=320
8a=320
a=40
Now that you know the cost of the accessories, you multiply that 40
by 7 to get the cost of the bike.
40(7)
280
The cost of the bike is $280.
The cost of the accessories are/is $40.
In quadrant I, when sin angle is 1/2, cos angle is (sqrt3)/2
The second term would be -3f^3 because when in descending order it is
6f^4 - 3f^3 - 2f^2 + 9f
