Answer:
y = 1/2x - 3/2
Step-by-step explanation:
The easiest way to find the inverse is to switch x and y and solve for y.
y = 2x + 3
x = 2y + 3 (Switch)
x-3 = 2y (Subtract y from both sides)
x/2 - 3/2 = y (Divide both sides by 2)

AB = </span>√(12²+5²) = √169 = 13 units
Answer:
4
Step-by-step explanation:
3y=12 divide both sides by 3
y=4
