2 answers:

8 0

Given a pre-image, you could use any single reflection, rotation, or translation, or combination of these transformations to re-position the pre-image on top of the image to confirm congruence. You would be able to visually see corresponding side lengths and corresponding angles measures are the same.

Answer:

Under a reflection, rotation, or translation, an image is congruent to its pre-image. If the image can be shown to be the result of one of these transformations, then the image is congruent to its pre-image. Because of the transitive property of congruence, the same will be true if the image is a result of a sequence of these transformations.

Answer:

SUM OF ALL ANGLES OF A TRIANGLE =180

THEREFORE,

X+8+2X-3+6X-5=180

9X=180

X=20.

THEREFORE,<J=X+8=20+8=28

<K=6X-5=6*20-5=120-5=115

<L=2X-3=2*20-3=40-3=37.

Point A is on a number line halfway between -17 and 5. Point B is halfway between point A and 0. What integer does point B reprs

Korolek [52]

Answer:

-3

Step-by-step explanation:

Point A is half way between -17 and 5. This is span has a total distance of 17 + 5 = 22. Half way is 11 units from -17 or 5. So -17 + 11 = -6.

Point B is halfway between A at -6 and 0. This is a distance of 6. So halfway is 3 units away at -3.

This may help:

There are $\frac{1}{3}$ gallons of lemonade.

Two friends share the lemonade.

What fraction of the lemonade does each friend receive?

To solve you do kcf or keep change flip.

You keep $\frac{1}{3}$ and change division to multiplication.

Then $\frac{2}{1}$ is changed to $\frac{1}{2}$

<span>The answer would be </span> $\frac{1}{6}$

Hope That Helps!
