Yea something is not right.if y=6 then you cant solve the system because you end up with x^2-4x-1
Answer:
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle
Step-by-step explanation:
Here, we want to select three statements that are true about CB
From what we have, CB runs from one edge to the other, passing through the center of the circle
Also, as we can see, AD is a radius as it is the distance from the center of the circle to the circumference; CB is twice this as it is the diameter
The diameter is a chord that passes through the center of the circle and it is a radius
So let us select the correct statements;
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle
