Area of a triangle = (height * base ) / 2
height = (Area * 2) / base
height = (49.5 * 2) / 9
height = 99 / 9
height = 10 cm²
Hey!
Okay, to solve this problem, we'd first have to multiply both sides by two. The reason we do this is to get
![y](https://tex.z-dn.net/?f=y)
on its own.
<em>Original Equation : </em>
![\frac{y}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7By%7D%7B2%7D%20)
<
<em>New Equation {Changed by Multiplying 2 on Both Sides} :</em>
![\frac{2y}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2y%7D%7B2%7D%20)
<
![2](https://tex.z-dn.net/?f=2%20)
(
![-3](https://tex.z-dn.net/?f=-3)
)
And we simplify the equation to get our answer.
<em>Old Equation :</em>
![\frac{2y}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2y%7D%7B2%7D%20)
<
![2](https://tex.z-dn.net/?f=2)
(
![-3](https://tex.z-dn.net/?f=-3)
)
<em>New Equation {Changed by Simplification} :</em>
y < -6
<em>So, the equation
![\frac{y}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7By%7D%7B2%7D%20)
< -3 simplified is</em>
y < -6.
Hope this helps!

Answer:
(-6,0)
Step-by-step explanation:
the y-axis is any (x number, 0)
$530.40/4= $132.60
$132.60 x 3=$397.80
Or
$530.40 x .75= $397.80
