A sinusoidal function whose frequency is 16π, maximum value is 12, minimum value is −6 has a y-intercept of 3. Which function could be the function described?

f(x)=3sin(x3)+9

f(x)=9sin(x3)+3

f(x)=9sin(6πx)+3

f(x)=3sin(6πx)+9

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?
