For this case we have the following functions:
![g (x) = 15-4x\\h (x) = x + 8](https://tex.z-dn.net/?f=g%20%28x%29%20%3D%2015-4x%5C%5Ch%20%28x%29%20%3D%20x%20%2B%208)
We must find
when
.
So:
![g (h (x)) = 15-4 (x + 8) =](https://tex.z-dn.net/?f=g%20%28h%20%28x%29%29%20%3D%2015-4%20%28x%20%2B%208%29%20%3D)
We apply distributive property to the terms within parentheses taking into account that:
![- * + = -\\15-4x-32 =](https://tex.z-dn.net/?f=-%20%2A%20%2B%20%3D%20-%5C%5C15-4x-32%20%3D)
We add similar terms taking into account that different signs are subtracted and the sign of the major is placed:
![-17-4x](https://tex.z-dn.net/?f=-17-4x)
Thus, we have to:
![g (h (x)) = - 17-4x](https://tex.z-dn.net/?f=g%20%28h%20%28x%29%29%20%3D%20-%2017-4x)
Then, with x = 2:
![g (h (2)) = - 17-4 (2) = - 17-8 = -25](https://tex.z-dn.net/?f=g%20%28h%20%282%29%29%20%3D%20-%2017-4%20%282%29%20%3D%20-%2017-8%20%3D%20-25)
Equal signs are added and the same sign is placed.
Answer:
![g (h (2)) = - 25](https://tex.z-dn.net/?f=g%20%28h%20%282%29%29%20%3D%20-%2025)
Yes bro...
the easiest way is to use 5C3
= 5! /(5-3)!3!
= 5(5-1)(5-2)(5-3)!/ (5-3)!3!
= 5×4×3×2/3×2
= 5×4 = 20ways
A. -8 Because there’s a negative in -4ac
Answer:
The answer would be "j"
Step-by-step explanation:
First, you would want to find the value of the original equation:
5(y + 2) + 4
Use order of operations and distribute the five.
5y + 10 + 4
5y +14
This is the value of the original equation
Now we can work through the other options, but because we already know the answer, lets see about that one.
5 x y + 5 x 2 + 4
Again, use order of operations.
Multiply first
5y + 10 + 4
and complete the equation
5y + 14, which equals our original equation.
Answer:
undefined. No one knows the answer. ¯\_(ツ)_/¯¯
