The two coordinates' x variables are the same, while the y variables change. This means that it is reflected over the x axis. Reflecting over the y axis would cause a change in the x variable, as it would have to move sideways, so this can't be the case since the x variable stays as 4 even after the reflection.
Answer:
yours is really good. it is something i would write defiantly! good job, and btw, im doing this just bc, you dont have to give me anything in return! :D have a nice day!

Answer:
Step-by-step explanation:
Basically we want to find x and then plug that in for angle B. How do we find x? Well, we know the angles are complimentary, which means theya dd to 90, so let's start with that.
A + B = 90
8x - 28 + 8x + 22 = 90
16x -6 = 90
16x = 96
x = 6
So there we go. Now to find B
B
8x+22
8(6)+22
48 + 22
70
Answer:
Hence the required equation of circle is
(x - 4)² + ( y - 1)² = 4
Step-by-step explanation:
The equation of a circle whose center (h, k) and radius r is given-
(x - h)² + (y - k)² = r²
Here given that-
Center = ( 4, 1) & r = 2
Equation of circle-
<em>( x - 4)² + ( y - 1)² = 2²</em>
<em>(x - 4)² + ( y - 1)² = 4</em>
<em>x² + 16 - 8 x + y² + 1 - 2 y = 4</em>
<em>x² + y² -8 x - 2 y + 13 = 0 </em>
Hence the required equation of circle is
(x - 4)² + ( y - 1)² = 4
0R
x² + y² - 8 x - 2 y + 13 = 0
