Answer:
4x -1530y+7388517.774
Step-by-step explanation:
4x- 45y × 34- -43 +π³÷√9-7889²×-2.488×1/3÷14÷2+83π-3×-3399.3884-10³
= 4x- 45y × 34+43 +π³÷√9-62236321×-2.488×1/3÷14÷2+83π-3×-3399.3884-1000
= 4x- 45y × 34+43 +31.018÷3-62236321×-2.488×1/3÷14÷2+83π-3×-3399.3884-1000
= 4x- 45y × 34+43 +10.34-62236321×-2.488×1/3÷14÷2+83π+13199.652
= 4x- 45y × 34+43 +10.34-62236321×-0.1185+260.752+13199.652
= 4x- 45y × 34+43 +10.34+7375004+260.752+13199.652
= 4x -1530y+7388517.774

option C is the correct answer my friend
ANSWER
![( f \circ \: g)( - 5)= -53](https://tex.z-dn.net/?f=%28%20f%20%5Ccirc%20%5C%3A%20g%29%28%20-%205%29%3D%20-53)
EXPLANATION
The given functions are:
f(x) = -2x - 7 and g(x) = -4x + 3
![( f \circ \: g)(x) = f(g(x))](https://tex.z-dn.net/?f=%28%20f%20%5Ccirc%20%5C%3A%20g%29%28x%29%20%3D%20f%28g%28x%29%29)
![( f \circ \: g)(x) = f( - 4x + 3)](https://tex.z-dn.net/?f=%28%20f%20%5Ccirc%20%5C%3A%20g%29%28x%29%20%3D%20f%28%20-%204x%20%2B%203%29)
![( f \circ \: g)(x) = - 2( - 4x + 3) - 7](https://tex.z-dn.net/?f=%28%20f%20%5Ccirc%20%5C%3A%20g%29%28x%29%20%3D%20%20-%202%28%20-%204x%20%2B%203%29%20-%207)
Expand:
![( f \circ \: g)(x) = 8x - 6 - 7](https://tex.z-dn.net/?f=%28%20f%20%5Ccirc%20%5C%3A%20g%29%28x%29%20%3D%20%208x%20%20-%206%20-%207)
![( f \circ \: g)(x) = 8x - 13](https://tex.z-dn.net/?f=%28%20f%20%5Ccirc%20%5C%3A%20g%29%28x%29%20%3D%20%208x%20%20-%2013)
We substitute x=-5
![( f \circ \: g)( - 5) = 8( - 5) - 13 = -53](https://tex.z-dn.net/?f=%28%20f%20%5Ccirc%20%5C%3A%20g%29%28%20-%205%29%20%3D%20%208%28%20-%205%29%20-%2013%20%3D%20-53)
