Hi there!
The answer to this question is: x=6
Step-by-step explanation:
All the points are being mirrored across the line x=6.
Answer: The correct option is (B) 
Step-by-step explanation: We are given the following system of equations :
We are to find the equation that could be the result of using substitution to solve the above system.
Substituting the value of x from equation (i) in equation (ii), we get
Thus, the required equation is
Option (B) is CORRECT.

28 - 45 = -17$ in her account
Answer: (5,-1)
Step-by-step explanation:
Explication étape par étape:
Compte tenu des expressions ';
A = 4 (x + 5) -8
B = x² + 15
Nous devons vérifier si A = B pour les deux valeurs de x à x = 1 et x = 3
à quand x = 1
A = 4 (1 + 5) -8
A = 4 (6) - 8
A = 24-8
A = 16
B = x² + 15
B = 1² + 15
B = 1 + 15
B = 16
Donc à quand x = 1, A = B = 16
quand x = 3
A = 4 (x + 5) -8
A = 4 (3 + 5) -8
A = 4 (8) - 8
A = 32-8
A = 24
B = 3² + 15
B = 9 + 15
B = 24
Également lorsque x = 3, A = B = 24
Cela montre que le postulat d'Emmas est juste.
