Why is the x coordinate undefined in picture 1?
It's not undefined anywhere else on the circle and is only undefined when the radius is 4.1... not when the radius is 4.2 or 4.

Answer:
This may be a bug in the Graph, lets sole it
(y-5)^2+(x+5)^2=4.1^2
(y-5)^2+(-9.1+5)^2=4.1^2
After Solving, Y=5
and you may use other graphing calculator such as GeoGebra, Mathwy, Photomath, it shows the answer Correctly
Answer:
Step-by-step explanation:
I am not exactly sure why it is undefined, but in my thought process below, I have noticed a trend, and it might help spark some thoughts.
(y-5)² + (x+5)² = r²
r = 4.1
x = -9.1
y = ?
If we try plugging in the known values to solve for y, then...
(y-5)² + (-9.1+5)² = 4.1²
(y-5)² + 16.81 = 16.81
(y-5)² = 0
y-5 = √0
y = 5
Now solving the equation does show that y exists, so maybe it's a domain/range problem. So let's find the domain and range.
The standard form is (x-a)² + (y-b)² = r², so since we have (y-5)² + (x+5)² = r², our (a is -5) and (b is 5) (and r is 4.1)
The domain of a circle is a-r ≤ x ≤ a+r, which gives (-5)-4.1 ≤ x ≤ (-5)+4.1
So our domain is -9.1 ≤ x ≤ -0.9
The range of a circle is b-r ≤ y ≤ b+r, which gives (5)-4.1 ≤ y ≤ (5)+4.1
So our range is 0.9 ≤ y ≤ 9.1
When x = -9.1, it is within the domain.
When y = 5, it is also within the domain.
Which means that the y value should exists.
BUT...
Here's a trend that I have noticed on desmos...
When (y-5)² + (x+5)² = r² and r = 4.1, y is undefined at the domain boundaries of -9.1 and -0.9
When (y-5)² + (x+5)² = r² and r = - 4.1, y is undefined at the domain boundaries of -9.1 and -0.9
When (y-5)² + (x+4)² = r² and r = 4.1, y is undefined at the domain boundaries of -8.1 and -0.1
When (y-4)² + (x+5)² = r² and r = 4.1, y is undefined at the domain boundaries of -9.1 and -0.9
When (y-5)² + (x+6)² = r² and r = 4.1, y is undefined at the domain boundaries of -10.1 and -1.9
When (y-6)² + (x+5)² = r² and r = 4.1, y is defined (y=6) at the domain boundaries of -9.1 and -0.9
When (y-6)² + (x+6)² = r² and r = 4.1, y is defined (y=6) at the domain boundaries of -10.1 and -1.9
When (y-6)² + (x+5)² = r² and r = 8.3, y is undefined at the domain boundaries of -13.3 and 3.3
When (y-6)² + (x+6)² = r² and r = 8.3, y is undefined at the domain boundaries of -14.3 and 2.3
I do not understand the trend despite of spending last night and today thinking about it. But Hope it helps. (If you saw me answering yesterday night, yea that's me, I ended up deleting it cuz I can't think it through, but then I thought that maybe it could help spark your thoughts, so here it is)

Answer:
x = 4 and y = 1
Step-by-step explanation:
The given equations are :
2x+5y = 13 ...(1)
3x-2y = 10 ...(2)
We can use elimination method to solve the given equations.
Multiply equation (1) by 3 and equation (2) by 2.
6x+15y=39 ...(3)
6x-4y=20 ...(4)
Subtract equation (3) from (4).
6x-4y-(6x+15y) = 20-39
6x-4y-6x-15y = -19
-19y=-19
y = 1
Put the value of y in equation (1).
2x+5y = 13
2x+5=13
2x=8
x = 4
So, the solution of the given equations are x = 4 and y = 1.

Answer:

Step-by-step explanation:
You are facing South. You make an about face, then turn 90 degrees right. What direction are you facing?
If you face South, perform an about face (180-degree turn), and then turn 90 degrees to the right, you will be facing West.
If you are facing South and make an about-face, then turn 90 degrees right, you will be facing West. This is because an about-face means to turn around 180 degrees, so you would now be facing North.
Then, turning 90 degrees to the right from the North would put you in the direction of the West. To summarize, if you start off facing South, making an about-face means turning around 180 degrees to face North.
From there, turning 90 degrees to the right puts you in the direction of the West. Therefore, you would be facing West after making an about-face and turning 90 degrees to the right.
