This is pretty easy its 16 1/5 hope this helps
Step-by-step explanation:
fg(x) =
![{(x - 4)}^{2} + 3(x - 4)](https://tex.z-dn.net/?f=%20%7B%28x%20-%204%29%7D%5E%7B2%7D%20%20%2B%203%28x%20-%204%29)
=
![{x}^{2} + 16 - 8x + 3x - 12](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%2016%20-%208x%20%2B%203x%20-%2012)
=
![{x}^{2} - 5x + 4](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%205x%20%2B%204)
I think it's 672 hope I helped
Answer:
-1
Step-by-step explanation:
you can look at the graph or the equation. input= x value output=y value
y=1/2x-1 is the equation
It says when x is zero what is y so put in 0 for x
y=1/2(0)-1
y=-1
Answer:
Your solution is (-10, 6).
Step-by-step explanation:
Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.
-5x + y = 56
x + y = -4
Let's change the second equation into one with one variable on each side.
y = -x - 4
Now, plug this into your first equation.
-5x + (-x - 4) = 56
Distribute the + sign.
-5x - x - 4 = 56
Combine the like terms.
-6x - 4 = 56
-6x = 60
Isolate x by dividing both sides by -6.
x = -10
Now plug this back into either equation.
-10 + y = -4
Add 10 to both sides to find y.
y = 6
Your solution is (-10, 6).
Check this by plugging in these values into the equation you have not checked yet.
-5(-10) + (6) = 56
50 + 6 = 56
56 = 56
Your solution is correct.
Hope this helps!
