Mhm.... Word problems.. So! Angle Side Angle :) proving that 2 triangles are equal.
You need to prove that DC is equal to BA. Now....
DB == AC.
which you can subtract BC from both sides!
DB-BC = AC-CB. leaving you with DC= AB

Now by Side Angle Side, The angles are =, 2 sides are equal, means the 2 triangles are equal :) If the triangles are equal, the 2 remaining sides must be equal

The thompson's need their garage door opener repaired. the table shows the service charge and hourly labor fees for two repair c

pentagon [3]

All you need to do here is know where and how to plug in the numbers. In each equation, you'll have an initial fee, and an hourly fee, so your equation will be
y = i + hx, where i = the initial fee, and h = the hourly fee

So, after plugging them in, here's what you get:
Doors Galore: y = 40 + 50x
G&H: y = 60 + 40x

Rectangle GHIJ is dilated to be a smaller shape. What is the name of the image after the dilation?

prisoha [69]

To know whether the shape is the pre-image or the resulting shape, we need to look at its name.

In this instance, the name of the pre-image is GHIJ.

The resulting name of the shape would be G'H'I'J'.

An apostrophe is placed after every letter to signify that it is the resulting coordinate of the original.
