Solve the proportion below 9/81=x/9 x= a.9 b.3 c.1 d.18

We want to isolate x.  One nice way of doing this is to multiply both sides of this equation by 9, as 9/9 is just 1 (one).  We then get:

9(9/81) = x, or 81/81, or 1.               x = 1.

Note that you could obtain the same result by reducing the fraction 9/81 to 1/9 and then noting that 1/9 = x/9.  It's obvious that x = 1 here.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
