the coordinates of the vertices of a polygon are (2,4) (6,4) (6,0) and (2,0). The polygon is dilated with a scale factor of 3/2
svlad2 [7]
Take the first point (2, 4)  a scale factor of 3/2 will move the x coordinate 2 to 2*3/2  = 3 and the y coordinate 4 will  be moved to 4*3/2 = 6.
So the image of ( 2, 4) will be ( 3, 6)  TH other verices will move in the same fashion.

One angle of a rhombus measures 108°, and the shorter diagonal is 9 inches long. Approximately how long is the side of the rhomb
vfiekz [6]

Answer:

8 inches

Step-by-step explanation:

A rhombus is a four sides quadrilateral with the four sides equal in length

A rhombus has 4 equal sides and the diagonal bisect at right angles

Adjacent sides = 9/2 = 4.5

we are to determine the value of the hypotenuse given the adjacent side and angle (108/2) = 54

Cos 54 = adjacent / hypotenuse

0.58778 = 4.5 / hypotenuse

hypotenuse = 4.5 / 0.58778

=7.6559

= 8 inches

Answer:

y = 7x - 5

Step-by-step explanation:

\frac{1}{2} (2y + 10) = 7x \\  \frac{2y}{2}  +  \frac{10}{2}  = 7x \\ y + 5 = 7x \\ y = 7x - 5
