Infinity because it's a cubic function with no restricted range or domain
3x-4y=10
-20-x+2y=10 then -30+2y=x now plug this in the other equation:
3(-30+2y)-4y=10
-90+6y-4y=10
2y=100
y=50
Answer:
The option that no represent a linear function is ![f(x)=3^x](https://tex.z-dn.net/?f=f%28x%29%3D3%5Ex)
Step-by-step explanation:
we know that
The graph of a linear function is a straight line
The equation of a linear function in slope intercept form is equal to
![f(x)=mx+b](https://tex.z-dn.net/?f=f%28x%29%3Dmx%2Bb)
where
m is the slope
b is the y-intercept
<u><em>Verify each case</em></u>
option 1) we have
![f(x)=3x-2](https://tex.z-dn.net/?f=f%28x%29%3D3x-2)
This option represent a linear function
where
m=3
b=-2
option 2) we have
![f(x)=x](https://tex.z-dn.net/?f=f%28x%29%3Dx)
This option represent a linear function
where
m=1
b=0
This option represent a linear direct variation function
option 3) we have
![f(x)=3^x](https://tex.z-dn.net/?f=f%28x%29%3D3%5Ex)
This option not represent a linear function
This option represent a exponential function
option 4) we have
![f(x)=3x](https://tex.z-dn.net/?f=f%28x%29%3D3x)
This option represent a linear function
where
m=3
b=0
This option represent a linear direct variation function
Answer:
A acute triangle looks like this..^^
Answer:
ab=1/12
Step-by-step explanation:
1/(4ab)+1/(3ab)-1/(2ab)=12
1/(ab)*[1/4+1/3-1/2]=1/12
1/(12ab)=1/12
ab=1
