If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

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?

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x
