Recall your d = rt, or distance = rate * time
notice, the time he took to cover 63 miles with the wind, is the same amount of time he took against it with 51 miles only, let's say, he took "t" hours long
and he was cycling at a rate of "r"
thus
solve for "r"
The coordinates of the midpoint:
(x₁,y₁) - the coordinates of one endpoint
(x₂,y₂) - the coordinates of the other endpoint
The midpoint is (14,26).
One endpoint is A(32,40).
The other endpoint is B.
The x-coordinate of B:
The y-coordinate of B:
The coordinates of B are (-4,12) - the answer is C.
If you would like to solve (5 * x^3 + 3 * x^2 - 5 * x + 4) + (8 * x^3 - 5 * x^2 + 8 * x + 9), you can calculate this using the following steps:
(5 * x^3 + 3 * x^2 - 5 * x + 4) + (8 * x^3 - 5 * x^2 + 8 * x + 9) = 5 * x^3 + 8 * x^3 + 3 * x^2 - 5 * x^2 - 5 * x + 8 * x + 4 + 9 = 13 * x^3 - 2 * x^2 + 3 * x + 13
The correct result would be 13 * x^3 - 2 * x^2 + 3 * x + 13.
>2 is also 40° since that is the rule of corresponding angles
