F(x) = 3x-1
g(x) = x+2
Find (f-g)(x), this means we need to subtract g from x.
(3x-1) - (x+2)
Subtract the like terms:
3x -x = 2x
-1 -2 = -3
Combine them to get 2x-3
The answer is A.
Together they equal 90 degrees.
Equation:
(0.1x - 22) + (0.3x - 54) = 90
Open parenthesis and simplify:
0.4x -76 = 90
0.4x = 166
DIvide:
Your final answer is x= 415
Hope this helps!
( -3, 6 )
b ( 0, 5 ) + ( -3, +1 ) = ( -3, 6 )
Answer:
6 or -1.5
Step-by-step explanation:
We can let this integer be x.
Therefore, according to the question we have:
![2x^2-18=9x](https://tex.z-dn.net/?f=2x%5E2-18%3D9x)
Subtracting 9x, we have a quadratic:
![2x^2-9x-18=0](https://tex.z-dn.net/?f=2x%5E2-9x-18%3D0)
Plugging into the quadratic equation:
![\frac{9+\sqrt{81+144}}{4}, \frac{9-\sqrt{81+144}}{4},](https://tex.z-dn.net/?f=%5Cfrac%7B9%2B%5Csqrt%7B81%2B144%7D%7D%7B4%7D%2C%20%5Cfrac%7B9-%5Csqrt%7B81%2B144%7D%7D%7B4%7D%2C)
the square root of 81+144 is 15, so the answer is either 6 or -1.5
