Answer: 4
Step-by-step explanation:
Given
PA=6, PD=4, BE=5
We know, If PEB is a secant that intersects the circle at E and B and PA be a tangent at A, then

Substitute the given values

Take 

Discard 

Answer:
x=3/2, y=10. (3/2, 10).
Step-by-step explanation:
2x-y=-7
4x-y=-4
--------------
-2(2x-y)=-2(-7)
4x-y=-4
---------------------
-4x+2y=14
4x-y=-4
-----------------
y=10
2x-10=-7
2x=-7+10
2x=3
x=3/2
Answer:
Step-by-step explanation:
Given system of equations in the question are,
-3x + y = -6
y = 
We can rewrite these equation as,
-3x + y = -6
y = 3x - 6 ------(1)
Table of input-output values for this equation will be,
x 0 1 2 3 4
y -6 -3 0 3 6
y =
------(2)
Table for this equation will be
x 0 2 4 6 8
y -1 0 1 2 3
By plotting these points on the graph we find (2, 0) is a common point in both the tables,
Therefore, (2, 0) is the only one solution of the given system of equations.
