Which values for a b will create infinitely many solutions?
1 answer:
Answer:
D
Step-by-step explanation:
Given the 2 equations
4x - Ay = 15 → (1)
- 4x + 6y = B → (2)
The system will have infinitely many solutions if the equations are equal
Multiply (2) by - 1
4x - 6y = - B
Equations are now equal, thus equate coefficients of relevant terms
- Ay = 6y ⇒ A = - 6
- B = 15 ⇒ B = - 15
Thus A = - 6, B = - 15 → D
