Answer:
pi x diameter
Step-by-step explanation:
To find the circumference of any given circle, multiply the radius by 2 to get the diameter, and then the diameter by pi (3.14)
Plug in (-1, 3) into both equations
Ax - 2y = 4
A(-1) - 2(3) = 4
-A - 6 = 4 Add 6 on both sides
-A = 10 Divide -1 on both sides
A = -10
5x + By = -1
5(-1) + B(3) = -1
-5 + 3B = -1 Add 5 on both sides
3B = 4 Divide 3 on both side
B = 
Answer:
x = 5
Step-by-step explanation:
I already answer this on another question you actually made, but here it is again:
To do this, you need to use the Thales theorem.
You can actually apply this theorem and choose two sides of the figure to do it.In this case, I will choose segment LM and MN and look for a ratio with DE and EF like this:
LM/MN = DE/EF
This theorem states that you can stablish a ratio between two segments assuming that you have at least two paralels lines, like DL || EM || FN
Therefore, it's time to replace the values of those segments and solve for X:
LM/MN = DE/EF
14/16 = 6x -9 / 4x + 4
7/8 = 6x - 9 / 4x + 4
7(4x+4) = 8(6x-9)
28x + 28 = 48x - 72
72 + 28 = 48x - 28x
100 = 20x
x = 100/20
x = 5
