Answer:
(x+9)^2 + (y+1)^2 = 100
Step-by-step explanation:
Since the question says diameter, we know the boundary in a circle. Therefore, we just need to find the center and radius.
The center is the midpoint of the two endpoints on a diameter.
Here, it is (-9, -1).
Therefore, the left part of the equation is (x- -9)^2 + (y - -1)^2 = (x+9)^2 + (y+1)^2.
The radius: sqrt(8^2 + 6^2) = 10
So the equation is (x+9)^2 + (y+1)^2 = 100
Answer:
x = 25
Step-by-step explanation:
Since these 2 angles are vertical angles, then they are both equal. Set up an equation and then solve it.
75 = 4x - 25
75 + 25 = 4x
100 = 4x
100/4 = 4x/4
25 = x

Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
x = w/3 - 2/3
The value of the output r(-3) in the given function is 2.
<h3>How to Interpret Graphs?</h3>
When we talk about graphs like this, it is pertinent to note that the x-values are the input values which would give us corresponding y-values which are the output values.
Now, we want to find r(-3) from the graph. This means we want to find the value on the y-axis when x = -3.
From the given graph, we see that when x = - 3, it is traced that the value of the output is y = 2.
Thus, the value of the output r(-3) in the given function is 2.
