Rewrite x - 2y = 8 using function notation. A) x - 2f(x) = 8 B) f(x) = -x + 8 C) f(x) = 2x + 8 D) f(x) = 1 2 x - 4
2 answers:
That would be f(x) = 1/2 x - 4
Answer:
D
Step-by-step explanation:
A first order equation has the following format:
In function notation, we use y = f(x), so:
In this problem:
x - 2y = 8
(-2y = 8 - x)*(-1)
2y = x - 8
y = (1/2)x - 4
f(x) = (1/2)x - 4
So the correct answer is
D

Answer:
x = 1/2
Step-by-step explanation:
2x + 3 = 4x + 2
-2x -2x
3 = 2x + 2
-2 -2
1 = 2x
Divide both sides by 2x
x = 1/2
