The expression which represents the function required to be generated; (f +g)(x) as in the task content is; 13x -2.
<h3>What is the expression which represents the function required?</h3>
It follows from the function definitions in the task content that the functions given are;
f(x) = 4x +5
g(x) = 9x -7
Hence, the value of (f +g)(x) = f(x) + g(x) and ultimately;
= 4x +5 + 9x -7
= 13x -2

Answer:
x=-5, y=5 or (-5,5)
Step-by-step explanation:
We can do elimination with this
this means we should first multiply -5x-4y=5 by 2
this would make it -10x-8y=10
we can now subtract this from the original equation
-8x-8y=0 - (-10x-8y=10)
the ys would cancel out
so this would equal
2x=-10
x=-5
now we can plug this back into the equation to find y
-8(-5)-8y=0
40-8y=0
-8y=-40
y=5
