(4/9)/x= 12
Multiply both sides by x
4/9=12x
Divide both sides by 12
(4/9)*(1/12)= 4/108
4/108= 1/27
Final answer: 1/27
<span>We know that for two vectors u and v we have that the cross product is equal to :
(u2v3 - u3v2) i + (u3v1 - u1v3) j + (u1v2 - u2v1) k
Then we have that m x n : ( (2 *-4) - (-5 * -2) ) i + ( (-5*6) - (3 *-4) )j + ( ( 3*-2) - (2*6))k
which becomes ( -8 - 10) i + ( -30 + 12) j + ( -6 - 12) k
Thus the vector product of m and n is -18 i - 18j -18k</span>
How should you write the proportion 9:36 = 10:40 using words?

B. 9 is to 10 as 36 is to 40
C. 36 is to 9 as 10 is to 40
D. 9 is to 36 as 10 is to 40
You are given two points on a line, and told that the function is "direct variation." You can save a lot of time by recognizing that the y-intercept here is zero (0). Thus, the line passes through the origin.
A line through (2,14) and (4,38) is NOT direct variation, because the line connecting those two points does NOT pass through the origin, and thus has a vertical intercept.
