Part A
4.8 inches
Part B
3.125 miles
Use the midpoint formula for the midpoint (xm, ym) between (x1,y1) and (x2,y2);
xm = (x1 +x2)/2
ym = (y1 +y2)/2
Because (x1,y1) = (5,8) and (x2,y2) = (11,6), therefore
xm = (x1 + x2)/2 = (5+11)2 =8
ym = (8+6)/2 = 7
The midpoint is (8,7).
Answer: a

Answer:
(x, y) = (-4, -15)
Step-by-step explanation:
Perhaps you want the solution to ...
y = 3/4x -12
y = -4x -31
Equating the two expressions for y gives ...
3/4x -12 = -4x -31
3/4x = -4x -19 . . . . . add 12
3x = -16x -76 . . . . . multiply by 4
19x = -76 . . . . . . . . . add 16x
x = -76/19 = -4 . . . . divide by 19
y = (3/4)(-4) -12 = -15 . . . . use the first equation to find y
The solution to this system of equations is ...
(x, y) = (-4, -15)
