Step-by-step explanation:
18+ 5(2x + 5) = 12
18 + 10x + 25 = 12
43 + 10x = 12
10x = 12 -43
10x = -31
x = -3.1
An easy way to do this is to parameterize the directed line segment from B to A by the function

with 0 ≤ t ≤ 1.
The point P₂ splits up AB so that BP₂ = 3/8 AB and AP₂ = 5/8 AB. Then we reach the point P₂ when t = 3/8, so its coordinates are

Answer:
B) In Step 2, the multiplication relationship shown should have been divided.
Step-by-step explanation:
Ok, C is 16 feet below the sea level = -16
D is below the sea level is 1/2 of the elevation of city it's mean
-16 divided 1/2 = -8
Solve: -8 multiply 2 is -16
