Here is how to work it with long division.
Answer:
The equation is: y = 1/2x + 7
Step-by-step explanation:
The slope of j is -2. The slope of a line perpendicular to line j has a negative inverse: 1/2. The point is (-8, 3).
Use the point slope form of the equation:
y - y1 = m(x - x1)
Substitute:
y - 3 = 1/2(x - (-8))
y - 3 = 1/2x + 4
y = 1/2x + 4 + 3
y = 1/2x + 7
Proof:
Solve for f(x) when x = -8.
f(x) = 1/2x + 7
f(-8) = 1/2(-8) + 7
= -8/2 + 7
= -4 + 7
= 3, giving the point (-8, 3)
Answer:
Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:
1. You have that t<span>he largest doll is 12 inches tall. The height of each of the other dolls is 7/10 the height of the next larger doll. Therefore, you have:
We don't know the number of dolls, so:
x=12(7/10)^(n-1)
Where x is the height of the doll and n is the number of the doll
The answer is: </span>x=12(7/10)^(n-1)
