Answer:

16/45

Step-by-step explanation:

Step 1: When dividing fractions, use “KFC”. It means Keep the first fraction, Flip the second one, and

Change it to multiplication

-4/20 ÷ -9/16 → -4/20 ∙ 16/-9

Step 2: Reduce any fractions if necessary, it makes multiplying them easier and you will have to reduce anyway at the end. It’s easier arithmetic to reduce at this step. The first fraction reduces because both the numerator and denominator are divisible by 4.

-1/5 ∙ 16/-9

Step 3: Multiply numerators and denominators together to get one fraction

(-16)/(-45)

Step 4: Cancel out the negatives, a negative divided by a negative is a positive. Our final answer is

16/45

Point K is located at (7,4) in the coordinate plane. Its image is created by the following rule:

Fynjy0 [20]

We are given coordinate of K point (7,4).

We need to find the new coordinate of K' point.

Given rule is K' = Ro 270°^(k).

That represents rotation of k 270 degree about the origin.

<em>The rule for rotation of 270 degree about the origin is as following:</em>

<em>(x, y) --------> (y, -x).</em>

Now, applying same rule on point (7,4).

(7,4) -----------> (4,-7).

<h3>Therefore, the coordinates of k' is (4,-7).</h3><h3>Correct option is A. (4,-7).</h3>

Can soemone help meee ):

I don't know the answer but my tip would be to split the shape the way I did it, find the lengths of each side, and then find the area for each individual shape.

Then add all the areas together.
