<u>To find the constant of proportionality:</u>
⇒ must define constant of proportionality
⇒ <em>Constant of Proportionality: ratio of two proportional values at a </em>
constant value
⇒ (in this case) two proportional values are x and y
<u>The ratio between x and y is equal to</u>
![\frac{y}{x} =\frac{66}{1.2}=55](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7Bx%7D%20%3D%5Cfrac%7B66%7D%7B1.2%7D%3D55)
<u>Answer:</u> <u>55</u> or <u>Choice 1</u>
<u></u>
Hope that helps!
You would use distributive property 5x(2×+x)+50
X=-1
12/-4=-3
-3+2=-1
