If any of you guys know the answer to this I really appreciate because I don’t know it, it’s also a check all that apply too.

If the value of cos330°is√3/2 then find cos 165°.

Which is the graph of this function 3 square root of x plus one if

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
