The answer is D because the line is going down over time
Step-by-step explanation:
sin(s+t) = sin(s)+cos(t) which results
(sin(s)×cos(t))/(cos(s)cos(t)) + (cos(s)×sin(t))/(cos(s)cos(t))
knowing that tan=sin/cos and that cos/cos=1 and sin/sin=1
resulting tan s ×1 + tan t × 1 = tan s + tan t
You will have to use trial and error in order to find the values for x and y.
Just keep plugging values until you get 7.
I found x is equal to 2 and y is equal to 5.
3(2) + (1/5)5 = 7
6 + 5/5 = 7
6 + 1 = 7
7 = 7
Change x to y, and y to x.
solve for y:
Your answer is:
