Answer:
D. 2x + y = -4
Step-by-step explanation:
Standard form for the equation of a line is Ax + By =C where A is a positive integer and B and C are integers
y + 1 = -2x - 3
Add 2x to each side
2x+y + 1 = -2x+2x - 3
2x+y +1 = -3
Subtract 1 from each side
2x+y +1-1 = -3-1
2x+y = -4

Step-by-step explanation:?
Answer:
h(x) = x/2 - 1/2
Step-by-step explanation:
Here's the procedure for finding the inverse function algebraically:
1. Replace the label 'f(x)' with the label 'y:' y = 2x + 1
2. Interchange x and y: x = 2y + 1
3. Solve the resulting equation for y: 2y = x - 1, or y = (1/2)(x - 1) or y = x/2 - 1/2
This result corresponds to the 1st given possible answer choice.
The desired inverse function is h(x) = x/2 - 1/2
