Given the graph of a system consisting of a linear and a quadratic equation, if the line is tangent to the original quadratic, how many solutions does the system have?
a. infinity many
b. 0
c. 2
d. 1
How does the number of solutions in a linear system compare to a system with a linear and a quadratic equation?
a. A linear system can have 0, 1 or 2 solutions. A linear-quadratic system can have 0, 1 or infinite solutions.
b. Both can have 0, 1 or 2 solutions.
c. Both can have 0, 1 or infi ite solutions.
d. A linear system can have 0, 1 or infinite solutions. A linear-quadratic system can have 0, 1 or 2 solutions.
The graph shows a linear-quadratic system composed of a parabola and a line, which is represented by the equation y=2. What is/are the solution(s) of the system?
a. no solution
b. (0, 1)
c. (1, 2) and (-1, 2)
d. (1, 2)
When solving {y+9=2x
{y+1=3(x+4)^2, the following is obtained. What does this value tell you about the solutions to the system? x=
a. Since the discriminant is negative, there are no real solutions. So there is no solution to this system.
b. Since the discriminant is positive, there are two real solutions. So there are two solutions to this system.
c. Since the discriminant is negative, there are two complex solutions. So there are two solutions to this system.
d. Since the discriminant is positive, there are no real solution. So there is no solution to this system.
