Answer:
-0.75
Step-by-step explanation:
Rearange to get y by its self.
3x+4y=8
Minus the 3x
4y=8-3x
Divide by 4
y=2-0.75x
Simply solve for x. Divide both sides by -3. Since you are dividing by a negative, flip the inequality sign. This gives you x<-2.
Note that the answer is x is less than or equal to -2. I am unable to insert the correct symbol on my keyboard.
A logarithmic function without a subscript means that it must be log base 10.
![\log_{10}987=a](https://tex.z-dn.net/?f=%5Clog_%7B10%7D987%3Da)
When learning about logarithms, a textbook/teacher provides their students with the following general equations
![\log_yx=z](https://tex.z-dn.net/?f=%5Clog_yx%3Dz)
![y^z=x](https://tex.z-dn.net/?f=y%5Ez%3Dx)
Hopefully you are familiar with this. Using the equations that I just showed, we can change the equation
to ![10^a=987](https://tex.z-dn.net/?f=10%5Ea%3D987)
This would make answer choice C correct.
