Geometry, SEMI-EASY question. I will give brainliest. Just want to double-check.

SashulF [63]

Answer:

Option B

Step-by-step explanation:

Let the point O is the origin.

Then the coordinates of the vertices A,B and C will be,

A → (-12, -8)

B → (-8, 0)

C → (-6, -4)

Rule for the dilation of a point (x, y) by scale factor 'k' about the origin is,

(x, y) → (kx, ky)

By this rule, coordinates of the vertices of the image triangle will be,

If k = $\frac{1}{2}$ ,

A(-12, -8) → A'(-6, -4)

B(-8, 0) → B'(-4, 0)

C(-6, -4) → C'(-3, -2)

From the given options,

Option B is the answer.

Help please asappppppppp

Answer:

First Equation: 6a-23

Second Equation: 5a-20

Step-by-step explanation:

So, I think you want me to answer part 2...

For the first equation, we can see that the denominator stays the exact same, meaning the numerator will also not change.

For the second equation, we can see the denominator changed from a-3 to 5a-15. The denominator was simply multiplied by 5. Since the denominator was multiplied by five we must multiply the numerator by five as well.

5(a-4)

5a-20

Hope this helps :)
