Step-by-step explanation:

AA stands for "angle, angle" and means that the triangles have two of their angles equal.

SAS stands for "side, angle, side" and means that we have two triangles where the ratio between two sides is the same as the ratio between another two sides  and we we also know the included angles are equal.

SSS stands for "side, side, side" and means that we have two triangles with all three pairs of corresponding sides in the same ratio.

Here we can easily see that two angles are equal

∠CYK and ∠KZP∠CKY and ∠PKZ (they're cross angles)

Dilate Point B by a scale factor of 3:

Answers

imma have to say (4,3) sorry if i’m wrong

We can write the coordinates of the vertices of the triangle after dilation by a scale factor as -

C'(9, 6)

B'(0, 12)

A'(12, 12)

What is dilation?

Dilation is the enlargement or shrinking of the coordinates.

Given is a triangle as shown in the image.

The coordinates of the vertices of the triangle are -

C(3, 2)

B(0, 4)

A(4, 4)

For the dilation by a scale factor of {K} = 3, we can write -

C'(3 x 3, 2 x 3) = C'(9, 6)

B'(0 x 3, 4 x 3) = B'(0, 12)

A'(4 x 3, 4 x 3) = A'(12, 12)

Therefore, we can write the coordinates of the vertices of the triangle after dilation by a scale factor as -

C'(9, 6)

B'(0, 12)

A'(12, 12)

Solve the system of equations - 8x - 5y = -13 and - 4x – 5y = 11 by
combining the equations.

Answers

Answer:

(6,-7)

Step-by-step explanation:

subtract them:

-8x - 5y = -13

-4x - 5y = 11

you get

-4x = -24

so x = 6

plug x into the second equation:

-24 - 5y = 11

-5y = 35

y = -7

so your solution is (6,-7).

Answer:

Your solution is (6, -7).

Step-by-step explanation:

Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.

-8x - 5y = -13

-4x - 5y = 11

Let's change the second equation into one with one variable on each side.

-5y = 4x + 11

y = -4/5x - 11/5

Now, plug this into your first equation.

-8x - 5(-4/5x - 11/5) = -13

Distribute the -5 sign.

-8x + 4x + 11 = -13

Combine the like terms.

-4x + 11 = -13

-4x = -24

Isolate x by dividing both sides by -4.

x = -24/-4

x = 6

Now plug this back into either equation.

y = -4/5(6) - 11/5

Multiply.

y = -24/5 - 11/5

Subtract.

y = -35/5

Simplify.

y = -7

Your solution is (6, -7).

Check this by plugging in these values into the equation you have not checked yet.

-8(6) - 5(-7) = -13

-48 + 35 = -13

-13 = -13

Your solution is correct.

Hope this helps!
