Answer: 1,2,3, and 5

Step-by-step explanation:

The isometries that preserve a shapes angles and line segments making the pre image congruent to the (post) image are :

Reflections, rotations, translations

These are rigid transformations. Think of your ruler. If you flip it, slide it, or rotate it around, did the ruler change shape? No. Just positions.

If you dilate something, you are either making it larger or smaller, therefore changing the size of the shape.

Anything that has dilation in its transformation does not have congruent shapes.

A shop keeper has 8 gallons, 3 quarts,
ioda

Answer:

I believe it would be 86 cups left of milk.

Step-by-step explanation:

8 gallons= 128 cups of milk

3 quarts= 12 cups

Plus the 1 cup of milk he had equals 141 of milk in total

Now the customer wants 2 gallons (32 cups of milk), 5 quarts ( 20 cups), and 3 cups which is 55 cups of milk.

Now we minus what the customer bought from what the shop keeper had so:

55-141=86

2x-y=-6<br>3x-4y=-4<br>Solve using elimination and then substitution
Alinara [238K]
Okay, so first you are going to decide whether to solve for x or solve for y. I am going to solve for x. In order to do so, you must get x by itself.
2x-y=-6
2x=y-6[ [tex]3x-4y=-4
3x=4y-4 \\ x= \frac{4y-4}{3}
The next step is to set both equations equal to each other in order to find y.
\frac{y-\frac{y-6}{2}= \frac{4y-4}{3} \\ 3(y-6)=2(4y-4) \\ 3y-18=8y-8 \\ -10=5y \\ y=-26}{2} [/tex]

So now you know that y=-2. The next part is substitution. All you have to do is pick on of the equations and plug in the y value to get the x value.

So your answer to the question is (-4,-2). I hope I've helped you understand how to solve these types of problems. If you have any questions, don't hesitate to ask.

Whats has the same slope of 6x-3y=9
Crank

Answer:


Step-by-step explanation:

when you put it into slope intercept form you get

y=2x-3

2 is the slope, so

y=2x+3 would have the same slope which means these lines are parallel.
