<span>1) y varies directly with x, then we have: y = kx, k is the constant of variation
y = kx
14 = - 4k
k = 14/- 4, or - 7/2, or - 3.5
y = kx
y = - 3.5(- 6)
y=21
2) </span><span>201.6 is the right answer.see the procedure used in Q1.
3) K = y/x
= 9/12
= 3/4</span>
length times width times height
Inclusive means less than or bigger than and
equal
the first one is correct

______________________________
<h3>1.) Subtract 14 from both sides:</h3>
Cancels Out
<em> - We do this because we have to get 2 variables/numbers on each side of the equals, and the only way to do so is to cancels other numbers out by doing the opposite of what we see. </em>
<u>Equation at the end of Step 1: </u>
÷ 
<h3>2.) Multiply both sides by −0.8:</h3>
×
Cancels Out
