Answer:
![a=7.5](https://tex.z-dn.net/?f=a%3D7.5)
Step-by-step explanation:
Given the function
and the output
when
, we can write the equation:
![6a-15=30](https://tex.z-dn.net/?f=6a-15%3D30)
![6a=45](https://tex.z-dn.net/?f=6a%3D45)
![a=7.5](https://tex.z-dn.net/?f=a%3D7.5)
We can insert the value of
into the function to verify the output equals
:
![f(a) = 6a-15](https://tex.z-dn.net/?f=f%28a%29%20%3D%206a-15)
![= 6(7.5)-15](https://tex.z-dn.net/?f=%3D%206%287.5%29-15)
![=30](https://tex.z-dn.net/?f=%3D30)
∴ We have verified that ![a=7.5](https://tex.z-dn.net/?f=a%3D7.5)
Hope this helps :)
