Answer:
SSS
Step-by-step explanation:
REM and DME share a side. This side is of course congruent.
In addition, sides RM and ED are marked as congruent, as are RE and MD.
All three corresponding sides of each triangle are congruent, which proves the triangles' congruency.
No information is given about the angles in these triangles, so none of the other theorem answer choices are valid.

Answer:
x=0
Step-by-step explanation:
X -8 = -8
Add 8 to both sides to get x alone
X = 8 - 8
X = 0
Answer: (x,y) → (2x,2y) .
Step-by-step explanation:
- A dilation is a transformation that changes the size of the image. It either shrink or enlarge a shape by using a scale factor about a center of dilation.
If we transform point (x,y) by using dilation with scale factor k (assume center of dilation at (0,0) then the coordinate of the image will be (kx,ky).
So, the coordinate expression represents the coordinates of any point after dilation by a scale factor of 2:
(x,y) → (2x,2y) .
Answer:
Step-by-step explanation:
<u>No Solutions</u>
There will be no solutions when the left side is inconsistent with the right side:
2x +5 +2x +3x = 7x +1
7x +5 = 7x +1 . . . . . . no value of x will make this true
__
<u>One Solution</u>
There will be one solution when the left side and right side are not inconsistent and not the same.
2x +5 +2x +3x = 6x +1
7x +5 = 6x +1
x = -4 . . . . . . . . add -6x-5 to both sides
__
<u>Infinitely Many Solutions</u>
There will be an infinite number of solutions when the equation is true for any value of x. This will be the case when the left side and right side are identical.
2x +5 +2x +3x = 7x +5
7x +5 = 7x +5 . . . . . true for all values of x

<em>Comment on these solutions</em>
You have not provided the contents of any of the drop-down menus, so we cannot say for certain what the answers should be--except in the case of "infinitely many solutions." For "no solutions", the coefficient of x must be 7 and the constant must not be 5. For "one solution" the coefficient of x cannot be 7, and the constant can be anything.
