Answer: Slope is m = 2/3
Step-by-step explanation:
-You have exactly four points on a table:
-Use the slope formula and use any two points from those four points in order to find the slope:
-The two points I use are 
and 
for the equation:
So, the slope of the table is 
.
Answer:
27.324$
Step-by-step explanation:
To find out what 8% of 25.30 is, divide 8 by 100 and get 0.08.
Then, multiply 25.30 by 0.08 and get your answer of 2.024. So, 8% of 25.30 is 2.024.
Since we must add the 8%, we must add 2.024 and 25.30 together. The answer will be 27.324.
Rounded, the answer will be 27.32$
Therefore, the answer is 27.32$.

Answer:
So first subtract 14 from 32
That means that -6y+4y = 18
Simplify the left side 4-6=-2
-2y = 18
Divide by -2
<u>-9 = y</u>
Step-by-step explanation:
Let the sides of the polygon (which is a triangle, by the way) be x, y and z. The sum of x, y and z is the perimeter of the original poly, and this equals 18 cm.
Letting f be the scale factor, f(18 cm) = 12 cm. Then f=2/3.
The dilation reduces the size of the polygon by a factor of 1/3, producing a similar polygon which is 2/3 the size of the original one.
In each case we have 3 side lengths but no angles. We can use Heron's formula to obtain the area in each case. Look up Heron's formula. In one version of this formula, p is half the actual perimeter, meaning that p is 18 cm / 2 for the first triangle and 12 cm / 2 for the second.
The area of the first triangle would be
A18 = sqrt( 9(9-x)(9-y)(9-z) )
whereas
A12 = sqrt( 6(6-x*a)(6-y*a)(6-z*a) ), where a represents the dilation factor 2/3.
Then the ratio of the areas of the 2 triangles is
sqrt( 6(6-x*a)(6-y*a)(6-z*a) )
---------------------------------------
sqrt( 9(9-x)(9-y)(9-z) )
