The x value will change to y avlue and vice versa
so x---> y and y---> x
(x,y) --> (y,x)
B
A) From the graph,
.. radius of M is 1
.. radius of N is 3
B) The "point of tangency" is the one point where the circles and tangent line meet. That point is (2, 1).
C) The horizontal tangent line has equation
.. y = 1
Step-by-step explanation:
a whole circle is 360°.
if you take away 40°, how many are left ?
that is absolutely the same as the question, when I have 15 apples and 6 are eaten, how many are left ?
well, 15-6 = 9 apples are left.
and so, 360-40 = 320° are left.
X represents the number
4x+13=(1/2)x-8 this is the equation
4x-(1/2)x=(-8)-13 combine like terms
(3 1/2)x=-21 simplify!
(7/2)x=-21 convert 3 1/2 into a fraction
x=(-21)(2/7) multiply both sides by 2/7 in order to isolate x
The answer is X= -6
