Answer:

Step-by-step explanation:

Because this whole problem focuses on the addition of mixed numbers, we can drop the parentheses right now without affecting the problem solution.

The two denominators shown are 4 and 3; the LCD is therefore 12.

Rewriting the problem, we get:

1 3/12 + 3 8/12 + 5 9/12, or

3 + 8 + 9

1 + 3 + 5 + ----------------

This simplifies to 9 20/12, or 10 8/12, or 10 2/3 (answer)

The tool I used for modellin is MS Excel. As you on the left side of the picture, I tabulate the x and y coordinates with respect to their columns. Then, I plotted it using the scatter plot graph. In this type of graph, only plots are drawn on the Cartesian plane. Next, I created a trendline as represented by the blue dashed line. There are options to the degree of your trendline: linear, polynomial or exponential. The closes fit is the polynomial with a degree of 2. An option is listed there in displaying the equation. The equation modelled by regression through data fitting is:
y = x² - 4x+1

Δ ABC and Δ A"B"C" is,

∠C and ∠C" are congruent after both the translation and dilation.

Step-by-step explanation:

Δ ABC is translated by the rule (x +1, y +1) and then dilated by a scale factor of 2 centered at the origin and the new triangle which we get is named as Δ A"B"C" .

Now, among the given statements the one which describes the properties of

Δ ABC and Δ A"B"C" is,

∠C and ∠C" are congruent after both the translation and dilation.
