Find value of m either add or subtract for m
Answer:
y = 25
Step-by-step explanation:
![30=\frac{6}{5} y\\\\\frac{6}{5} y=30\\\\(\frac{6}{5} y)5=30*5\\\\6y=150\\\\\frac{6y=150}{6}\\\\\boxed{y=25}](https://tex.z-dn.net/?f=30%3D%5Cfrac%7B6%7D%7B5%7D%20y%5C%5C%5C%5C%5Cfrac%7B6%7D%7B5%7D%20y%3D30%5C%5C%5C%5C%28%5Cfrac%7B6%7D%7B5%7D%20y%295%3D30%2A5%5C%5C%5C%5C6y%3D150%5C%5C%5C%5C%5Cfrac%7B6y%3D150%7D%7B6%7D%5C%5C%5C%5C%5Cboxed%7By%3D25%7D)

<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>

Answer:
Option B.
Step-by-step explanation:
The given quadratic equation is
![9x^2=4](https://tex.z-dn.net/?f=9x%5E2%3D4)
We need to find the solution of given quadratic equation.
Divide both sides by 9.
![\frac{9x^2}{9}=\frac{4}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B9x%5E2%7D%7B9%7D%3D%5Cfrac%7B4%7D%7B9%7D)
![x^2=\frac{4}{9}](https://tex.z-dn.net/?f=x%5E2%3D%5Cfrac%7B4%7D%7B9%7D)
Taking square root on both sides.
![x=\pm\sqrt{\frac{4}{9}}](https://tex.z-dn.net/?f=x%3D%5Cpm%5Csqrt%7B%5Cfrac%7B4%7D%7B9%7D%7D)
![x=\pm\frac{2}{3}](https://tex.z-dn.net/?f=x%3D%5Cpm%5Cfrac%7B2%7D%7B3%7D)
The solution of given equation are
and
.
Therefore, the correct option is B.
