Ksivusya [100]
With A and its image one can get the dilation factor;
That is dilation scale factor = -6/-4 or 9/6 = 3/2
Therefore, to get the image of B we multiply the coordinates of B by the dilation factor; 
(1,4) 3/2 = (1.5, 6)
Thus the image of B = (1.5,6)

Explain why angle Y is congruent to angle B
DerKrebs [107]

<u><em>Note: It seems you may have unintentionally missed to add the complete question statement, but I will make sure to make you understand the concept of angle congruence anyways using which you may be able to clear all your queries regarding the concept.</em></u>

Answer:

When we say the angles Y and B are Congruent. It means these congruent angles have the same angle measured in degrees. (or in radians as both are units of measure for angles).

The figure a is also attached below to visualize the concept.

Step-by-step explanation:

When we say the angles Y and B are Congruent. It means these congruent angles have the same angle measured in degrees. (or in radians as both are units of measure for angles).

Here are some additional things to observe:

  • Angles are congruent as long as the angles are the same
  • they don't have to point in the same direction
  • they don't have to be made with lines of the same length.

For instance, below is the example. Where,

  • Angle Y is 42°
  • Angle B is 42°

As the measure of these angles is same. It means the angles Y and B are Congruent. The figure a is also attached below to visualize the concept.

How many solutions are there to the systems of equations below? (PLEASE ANSWER + 10 POINTS!!!)
krok68 [10]

y = x² + 3x - 7

y - 5x + 8 → y = 5x - 8

5x - 8 = x² + 3x - 7 <em>substituted "y" in first equation with "5x - 8"</em>

0 = x² - 2x + 1 <em>subtracted 5x and added 8 to both sides</em>

0 = (x -1)(x - 1) <em>factored x² - 2x + 1 </em>

x = 1 <em>solved for "x"</em>

Now plug that "x = 1" into "y = 5x - 8" → y = 5(1) - 8 → y = 5 - 8 → y = -3

Solution is (1, -3) so there is only one solution.
