Polygon ABCD was dilated by a scale factor of 3/2 to form polygon A'B'C'D'. The scale factor used was 3/2. The length AB is 2 and the length A'B' is 3.
<h3>What is a
transformation?</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.
Dilation is the increase or decrease in the size of a figure.

Answer:
y=2x-8
Step-by-step explanation:
<em>Slope-Intercept Form </em>
<em>y=mx+b where y and x are variables, m is the slope, and b is the y-intercept</em>
<u>1. Find slope using the slope formula </u>
You now have
y=2x+b
<u>2. Plug in one of the given points into the equation and solve for b</u>
y=2x+b
2=2(5)+b
2=10+b
-8=b
<u>Final Answer:</u>
y=2x-8
It's easy once you spot the ones that can cross cancel!
Say we have the fractions 8/10 and 20/23. 
(it's easier to see on top of each other)
If you look diagonally , so 8 and 23 and 10 and 20, you can see that 10 and 20 have a common factor. So we divide it by the highest common factor to reduce those numbers, making it easier to multiply. 10 and 20 can become 1 and 2, dividing by 10. So now we are left with 8/1 and 2/23, and now we multiply normally going across so 16/23.
This works going both diagonals and simplifying both, but in that case it would be easier to try and simplify the fractions before cross multiplying them.
Basically: look for those diagonals and if they can be divided down by the highest common factor, go for it to make it easier to multiply normally afterwards.
Hope I helped!
Answer:
$4125.
Step-by-step explanation:
When solving for the principal we still need to use the formula 
.
Let's take all the variables that we do have available and list them out.
A = $4369.20
r = 3.3% or 0.033
n = 4 (Quarterly)
t = 21 months or 1.75 years
Now we can substitute the values and solve for the principal.
Now we need to divide both sides with 1.05919912849 to get the principal.
P = 4125.00339406 or $4125.
To check for our answer, we can simply substitute the values including the principal and excluding the total.
or 
3.4 + y = -6.85
Subtract 3.4 to both sides:
y = -6.85 - 3.4
y = -10.25
