Answer:
f(x) = 2/x and g(x) = 2/x
f(g(x)) = f(2/x) = 2/(2/x) = x
g(f(x)) = g(2/x) = 2/(2/x) = x
In this case, multiplying the two denominators of the fractions give 34 as the correct LCD.

Answer:
A) y = 1 - 2x
Step-by-step explanation:
Substitute the points given into all of the equations
Let's take point (1, -1)
A) y = 1 - 2x
-1 = 1 - 2(1)
-1 = 1 - 2
-1 = -1 ✓
B) y = -x - 1
-1 = -1 - 1
-1 = -2 ✘
C) y = x - 2
-1 = 1 - 2
-1 = -1 ✓
D) y = 2x - 1
-1 = 2(1) - 1
-1 = 2 - 1
-1 = 1 ✘
So far, lines A and C can be possible solutions. Let's try point (2, -3)
A) y = 1 - 2x
-3 = 1 - 2(2)
-3 = 1 - 4
-3 = -3 ✓
C) y = x - 2
-3 = 2 - 2
-3 = 0 ✘
Thus, line A is the correct answer
Answer:
1x+0y=-3
Step-by-step explanation:
Standard form is Ax+By=C where A, B, and C are integers
So x=-3 in standard form would be 1x+0y=-3
