Hello,
Adding the 2 equations,
x+y+x-y=k+k ==>2x=2k==>x=k
if x=k, y=k-k=0
solution is (k,0)
Answer:
4
Step-by-step explanation:
Answer:
The correct answer is 2x - y - 1 = 0
Step-by-step explanation:
To find this, use the ordered pair (1, 1) in any of the equations. If it results in a true statement then this can be an equation.
2x - y - 1 = 0
2(1) - (1) - 1 = 0
2 - 1 - 1 = 0
0 = 0 (TRUE STATEMENT)

Step-by-step explanation:
Answer:
m∠BDC = 43°
Step-by-step explanation:
According to the theorem every peripheral angle in the circle is equal to half value of central angle.
Angle m∠ADB is corresponding peripheral angle of central angle m∠AOB.
According to this m∠AOB = 2· m∠ADB = 2· 43 = 86°
If angle m∠BOC=m∠AOB= 86°
Angle m∠BDC is corresponding peripheral angle of central angle m∠BOC
According to this m∠BDC = m∠BOC/2 = 43°
Good luck!!!
