Supplementary = 180 Degrees

So the measure of angle U + the measure of angle V = 180 Degrees

The measure of angle V is 3 times the measure of angle U, so

U+3U=180 Degrees, which can be written as 4U=180

You can find the value of U by dividing both sides by 4

U=180/4=45 Degrees

Since you are trying to find the value of x that makes U and V supplementary, you would sustitute the value of 45 Degrees that was calculated for U into the equation given for x.

45 Degrees = 3x

To solve you divide both sides by 3

x=45/3=15

x = 15 Degrees

the vertices of PQR are P(-5,1), Q(-4,6), and R(-2,3), graph P"Q"R" after a composition of the transformations in the order they

horsena [70]

SOLUTION

We are told to translate; (x, y) to (x -8, y). This means we have to add - 8 to each value of x in P(-5,1), Q(-4,6), and R(-2,3).

In P(-5,1), x = -5 and y = 1

In Q(-4,6), x = -4 and y = 6 and

In R(-2,3), x = -2 and y = 3

$\begin{gathered} P(-5,\text{ 1) translates to (-5 -8, 1) }\rightarrow P^i(-13,\text{ 1)} \\ Q(-4,\text{ 6) translates to (-4 -8, 6) }\rightarrow Q^i(-12,\text{ 6)} \\ R(-2,\text{ 3) translates to (-2 -8, 3) }\rightarrow R^i(-10,\text{ 3)} \end{gathered}$

For the dilation centered at the origin k =2, simply multiply the value of k, which is 2 into the translations.

$\begin{gathered} At\text{ K = 2, }P^i(-13,\text{ 1) }\rightarrow\text{ }2(-13,\text{ 1) }\rightarrow\text{ }P^{ii}(-26,\text{ 2)} \\ Q^i(-12,\text{ 6) }\rightarrow\text{ }2(-12,\text{ 6) }\rightarrow\text{ Q}^{ii}(-24,\text{ 12)} \\ R^i(-10,\text{ 3) }\rightarrow\text{ }2(-10,\text{ 3) }\rightarrow\text{ R}^{ii}(-20,\text{ 6)} \end{gathered}$

Which ordered pair is a solution

NikAS [45]

Answer:

B) Only (-3, 5)

Step-by-step explanation:

Slot in the options into the equation

(-2, 4),

Compare with (x, y)

x = -2, y =4

y =-3x - 4

4 =( -3 * -2 ) - 4

4 = 6 - 4

This is not true hence, option A is wrong

Using (-3, 5)

x = -3, y= 5

5 = (-3*-3) - 4

5 = 9 - 4

This is correct hence, option B is correct

Option c is wrong because (-2,4) is not a solution to the equation

Option D is wrong because option B is correct
