stepan [7]

Answer:

Step-by-step explanation:

video store A : 15 + 1.75m

video store B : 7.5 + 2.25m

15 + 1.75m = 7.5 + 2.25m

15 - 7.5 = 2.25m - 1.75m

7.5 = 0.50m

7.5 / 0.50 = m

15 = m <=== there would have to be 15 movie rentals to make them equal

check...

15 + 1.75m                      7.50 + 2.25m

15 + 1.75(15) =                 7.50 + 2.25(15) =

41.25                               41.25

yep...it checks out

The vertices of a triangle are A(2,4),B(-1,-3),and C(3,6). Find the new vertices. Use the rule (x,y) &gt;&gt;&gt;(x-3,y+5)to tra
Mama L [17]

Answer:

A(-1,9), B(-4,2) and C(0,11)

Step-by-step explanation:

The vertices of a triangle are A(2,4),B(-1,-3),and C(3,6).

To translate, we use the rule (x,y) >>>(x-3,y+5)

For Vertex A(2,4),

The new vertex is (2-3, 4+5)=(-1,9)

For Vertex B(-1,-3)

The new vertex is (-1-3,-3+5)=(-4,2)

For Vertex C(3,6)

The new vertex is (3-3,6+5)=(0,11)

After translation of Vertex A, B and C by the given rule, the new points are A(-1,9), B(-4,2) and C(0,11)
