Hello me im desperate what is the domain of f (x) = (1/3)^x ?

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?

What is the area of the shaded sector?

Which statement about 6x2 + 7x – 10 is true?
