Use the rule (x,y) (3x,2y) to find the image for the preimage defined by the given points.
Elina [12.6K]

Answer: The points of the images are  (9,10), (15,6), (6,4)  and the image is not a rigid motion because the shape changes in side.

Step-by-step explanation:

Since it gives you the scale factor then find they coordinates by multiplying the coordinates by the scare factor.

A(3,5) → (3*3,5*2) → (9,10)

B( 5,3) → (5*3, 3*2) → (15,6)

C ( 2,3)→ (2*3, 2*2)→ ( 6,4)

5/12lb of dog food in each container.

This seems like a division problem so you would take (5/4) and divide it by 3 to make 3 equal groups meaning 5/12lb would be in each container.

I hope this helps, good luck!

The length of the base of a triangle is twice its height. If the area of the triangle is 64 square​ kilometers, find the height.
frez [133]
Area of a triangle = base x height / 2
64 = base x height / 2
(multiply 2 on both sides)
128 = base x height 
then if base= 16 and height = 8 then 16 x 8 = 128
thus the base is 16 which is twice the height:8
