The first equation is 1x + 1y = 8, satisfied by all four answers.
The second equation is 2x+3y =36; checking we find
2(-12)+3(20) = -24+60 = 36

Answer:
2/4 = 1/2
Step-by-step explanation:
Firstly expand cos(x - 30)....which is..
[cos x.cos 30 + sin x.sin 30]
If sin x = -1/2...then cos x = square root of 3/2
Then substitute the values into the expansion above....which...,
[(square root of 3/2)(square root of 3/2) + (-1/2)(1/2) ]
; 3/4 - 1/4 = 2/4
;Ans = 2/4 = 1/2

cant see the whole graph so can't really answer.
to answer this you should locate the x-coordinate on the x-axis and then go up and check wat is the collaborating y-coordinate that touches the line. and continue on.
<span>i got f(x) = −1/16 x^2 ,not sure though</span>
