Answer: c) -0.3
<u>Step-by-step explanation:</u>
Consider the left point as (x₁, y₁) and the right point as (x₂, y₂)
then (x₁, y₁) = (-6, -1) & (x₂, y₂) = (5, 1)
x₂ - x₁ = 5 - (-6) = 11
y₂ - y₁ = 1 - (-1) = 2
ratio of a:b = a/(a+b)
1 : 2 = 1/(1 + 2) = 1/3
x-coordinate: x₁ + ratio(x₂ - x₁) = -6 + (1/3) (11) = -7/3
y-coordinate: y₁ + ratio(y₂ - y₁) = -1 + (1/3) (2) = -1/3
x - hip-hop CDs
x+3 - rock CDs
6 hip-hop CDs, 9 rock CDs
3
multiply by 4
12
add 12
24
divide by 2
12
subtract 6
6
number 6 : 6(4) = 24... + 12 = 36...36/2 = 18.....- 6 = 12
number 8 : 8(4) = 32....+ 12 = 44...44/2 = 22....- 6 = 16
number 12: 12(4) = 48....+ 12 = 60...60/2 = 30....-6 = 24
well...by following these steps, it appears the original number doubles as a result.
