It's always easier to understand a concept by looking at specific examples with pictures, so I suggest looking at the dilation examples below first...before you try to internalize the steps listed below and that explain the general formula for dilating a point with coordinates of (2,4) by a scale factor of <span><span>12</span><span>12</span></span>.
<span><span>1) multiply both coordinates by scale factor<span>(<span><span>2⋅<span>12</span>,4⋅<span>12</span></span><span>2⋅<span>12</span>,4⋅<span>12</span></span></span>)</span></span><span>2)
2. Simplify(1,2)</span><span>3)
3. Graph(if required)<span> </span></span></span>
Answer:
$27.59
Step-by-step explanation:
1) First we calculate the sales tax:
30 x .15 = 4.5
30 - 4.5 = 25.5
2) Now we calculate sales tax
25.5 x .082 = 2.09
25.5 + 2.09 = $27.59
Since the interior is 170 the exteriro must be 10 degrees. There is a total of 360 degrees so 360/10=36 or 36 sides.
Answer:
-96
Step-by-step explanation:
15+11=26+7=33+(-129)=-96
Answer:
the slope is 4/3
Step-by-step explanation:
use the formula:
m=
where x1 and y1 can be any point and x2 and y2 can be any point.
I used the last relation as my x1,y1 and second last relation as my x2,y2 because it is easier to subtract them.
which is 8/6 or 4/3
