The relationship between the points is an illustration of similar shapes.
The length of AB is 0.43
The given parameters are:
From the question (see attachment), we have the following observations:
- BE corresponds to CD
- AB corresponds to AC
So, the equivalent ratio is:
Substitute known values
Express as fractions
Multiply both sides by 1.8
<em>AC = AB + BC</em>
So, we have:
Substitute 1.7 for BC
Multiply through by 5
Collect like terms
Divide both sides by 4
Approximate
Hence, the length of AB is 0.43

Answer:
idk sry bud
Step-by-step explanation:
I am not sure help. I’m bad at math trying to get free answers
1. Solve the given equation for y.
x - 5y = 15
-5y = -x + 15
y = (-x + 15)/-5
y = (x/5) - 3
y = (1/5)(x) - 3
The slope is 1/5. See it?
The equation we are looking for has a slope which is the negative inverse of the slope in the equation we just solved for y.
The slope for the equation we want is -5 which is the negative inverse of 1/5. Undetstand?
We have the slope of the new equation and one point is given.
Plot BOTH into the point-slope formula and solve for y. To solve for a variable means to isolate the variable ALONE on one side of the equation.
y - y_1 = m(x - x_1)...This is the point-slope formula. Our given point is (5,-2)
y - 5 = -5(x - (-2))
y - 5 = -5(x + 2)
We now solve for y and that's it.
y - 5 = -5x - 10
y = -5x - 10 + 5
The equation we want is y = -5x - 5.
