Angles TRS and VRW are vertical angles, so we can set them equal to each other to get x:
x+40=3x
40=2x
20=x
So the value of x is 20
Answer:
Step-by-step explanation:
Answer:- A.The independent variable is the input variable and should be represented by the x-axis.
Explanation:-
A. Correct.
B. Not correct.
<u>Reason</u>:- The independent variable is the input variable and should be represented by the x-axis.
C. Not correct.
<u>Reason</u>:- The dependent variable is the output variable and should be represented by y-axis.
D. Not correct.
<u>Reason</u>:-The dependent variable is the output variable and should be represented by y-axis.
The general equation given is x^2 - 4x + y^2 = -3. Transform this to an equation of a circle of the form x^2 + y^2 = r^2.
Use completing the square method:
x^2 - 4x + 4 + y^2 = -3 + 4
(x - 2)^2 + y^2 = 1
the center of the circle is (2,0) and r = 1
To check if it intersects the y axis, find the value of the x-intercept.
