Answer:
Option C is correct
The coordinate of C' or the transformed point of C is (-6, 5)
Step-by-step explanation:
From the given graph:
In triangle ABC:
Coordinate of C is:
C(-3, 4)
The rule of transformation is given:
We have to find the coordinate of C'.
Apply the transformation on coordinate C:
Therefore, the coordinate of C' is (-6, 5)
Answer:
Step-by-step explanation:
The quadratic formula is:
The discriminant of a quadratic is just the expression under the square root, or . This can tell us the number of solutions a quadratic has.
If the discriminant is:
- Positive = 2 real solutions
- Equal to Zero = 1 real double/repeated solution
- Negative = 0 real solutions, but 2 imaginary solutions
Our quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.
