You first start with adding the number in the parentheses,because none of them can add in this equation it stays the same:

(3x^2 + 3) + (3x ^2 + x + 4)

Since there is nothing that we can do while there are parenthaseese we remove them:

3x^2 + 3 + 3x ^2 + x + 4

Next add the x^2’s:

6x^2 + 3 + x + 4

Lastly the normal numbers:

6x^2 + 7 + x

Now that there are no more numbers that are the same, 6x^2 + x + 7 is your simplified equasion.

Hope this helps! :)

Which scatterplot correctly represents the table of values below? Number of years collecting stamps Number of stamps in collecti

schepotkina [342]

Answer:

C. A graph titled Years Collecting Stamps versus Stamps in Collection has years collecting stamps on the x-axis and stamps in collection on the y-axis. Points are at (2, 100), (3, 100), (3, 125), (4, 150), (4, 175), (5, 175)

Step-by-step explanation:

In the x-axis goes the values from the column 'Number of years collecting stamps' of the table. And In the y-axis goes the values from the column 'Number of stamps in collection' of the table.

To make the graph identify each pair of values in the plane and mark it.

Triangle RST was transformed using the rule (x, y) → (–x, –y). The vertices of the triangles are shown.

natta225 [31]

Answer:

Correct answer is:

The transformation was a 180° rotation about the origin.

Step-by-step explanation:

Given the triangle RST formed by points:

$R (1, 1),\\S (3, 1)\ and\\T (1, 6)$

is transformed using (x, y) → (–x, –y) such that coordinates of triangle R'S'T' :

$R' (-1, -1),\\S' (-3, -1)\ and\\T' (-1, -6)$

Please refer to the attached image for the given dimensions and coordinates.

It is clearly visible that:

The given triangle RST has coordinates in first quadrant.

and the resulting coordinates R'S'T' are in third quadrant.

The rotation of angle from 1st quadrant to 2nd quadrant is $90^\circ$ and

The rotation of angle from 2nd quadrant to 3rd quadrant is $90^\circ$ .

<em></em> $\therefore$ <em> total rotation is </em> $180^\circ$ .

Malachy was thinking of a number. Malachy halves the number and gets an answer of 67.3.

Nimfa-mama [501]

Step-by-step explanation:

Let the number be x.

ATQ,

Malachy halves the number and gets an answer of 67.3.

$\dfrac{x}{2}=67.3$

This the equation for the given statement.

It can also be written as :

$x=2\times 67.3\\\\x=134.6$

Hence, this is the required solution.
