F(x) and g(x) were inverse functions, then if f(a) = b, then g(b) = a
f(x) = (5x+1) / x g(x) = x / (5x+1)
f(1) = 6, but g(6) = 6/31 ≠ 1
So, f(x) and g(x) are NOT inverse functions.
Slope-intercept form looks like this: y = mx + b. For your equation, simply add 3x on both sides: y = 3x + 19.
C - Parenthesis first (3-1)=2, then distribute the 4. 4x2=8, next add 5, 8+5=13.
<span>x + 3y = 9
-x + y = -1
X = 3
Y = 2
