6 0

Answer:

c. sin 30 is positive and sin -30 is negative

Step-by-step explanation:

Picture the unit circle (which is attached). <u>Sine is like the y-coordinate.</u> And -30 and 30 on the unit circle both form equally-sized triangles, but -30 is underneath the x-axis, so it has a <u>negative y-coordinate.</u> 30 is above the x-axis, so it has a <u>positive y-coordinate.</u>

A) Necsito Ayudaa Con Eso&lt;br /&gt;ayuden Porfa&lt;br /-3x-7y=8 3x-2y=-44
STALIN [3.7K]
Hi! 

[1] -3x-7y=8
[2] 3x-2y=-44

lets take [1]
-3x-7y=8
-7y=8+3x
-7y-8=3x
3x=-7y-8

No use 3x=-7y-8 and put it in 3x-2y=-44
-7y-8-2y=-44
-9y-8=-44
-9y=-36
9y=36
y=4

then use y in 3x-2y=-44
3x-2(4)=-44
3x-8=-44
3x=-36
x=-12
Therefore, y = 4 and x = -12
