You have to add up all the sides of the box
Answer:
x = 1
Step-by-step explanation:
So first we have to identify what f(x) and g(x) equals. We can do this by looking at their y-intercept and determining their slope, by its rise/run
the two equations are:
y = -2x - 1
y = x + 2
now we solve
f(x) + g(x) = 0
substitute
-2x - 1 + x + 2 = 0
simplify
-x + 1 = 0
divide by -1
x - 1 = 0
add one on both sides
x = 1
Let
P1 = (x1, y1) = (4, 7)
P2 = (x2, y2) = (2, 3)
The first thing to do in this case is to find the distance between two points by the following equation:
d (P1, P2) = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
d (P1, P2) = root ((2-4) ^ 2 + (3-7) ^ 2) = 4.47
answer
The houses are separated 4.47 units.
