You replace the y with f(x)
So it becomes f(x)=2x+1
Answer:
AngleA +angleB=180
Step-by-step explanation:
3t-18t+4=-26
first you want to move the 4 to the other side of the equation so subtract that from both sides of the equation which gives you this 3t-18t=-30.
Next you would combine the like terms that are on the left side of the equation giving you -15t=-30. Now you want t by itself so you divide both sides by -15 which would give you t=2
4x = y
2x^2 - y = 0
2x^2 - 4x = 0
2x(x - 2) = 0
2x = 0 or x - 2 = 0
x = 0 or x = 2
y = 4(0) or y = 4(2)
y = 0 or y = 8
Therefore, solution set is {(0, 0), (2, 8)}
Answer:
the missing side length is ![(2x+5)](https://tex.z-dn.net/?f=%282x%2B5%29)
Step-by-step explanation:
we know that the volume of the rectangular prism is equal to
![v=LWH](https://tex.z-dn.net/?f=v%3DLWH)
In this problem we have
![v=L(x+4)(x+2)](https://tex.z-dn.net/?f=v%3DL%28x%2B4%29%28x%2B2%29)
![v=2x^3+17x^2+46x+40](https://tex.z-dn.net/?f=v%3D2x%5E3%2B17x%5E2%2B46x%2B40)
using a graphing tool find the x-intercepts of the function
see the attached figure
The x-intercepts are
![x=-4, x=-2.5, x=-2](https://tex.z-dn.net/?f=x%3D-4%2C%20x%3D-2.5%2C%20x%3D-2)
so
![v=2(x+2.5)(x+4)(x+2)](https://tex.z-dn.net/?f=v%3D2%28x%2B2.5%29%28x%2B4%29%28x%2B2%29)
![v=(2x+5)(x+4)(x+2)](https://tex.z-dn.net/?f=v%3D%282x%2B5%29%28x%2B4%29%28x%2B2%29)
therefore
the missing side length is ![(2x+5)](https://tex.z-dn.net/?f=%282x%2B5%29)
