b. It is a segment that touches the circle in exactly one point and makes a right angle with the radius.
Nothing really to be explained, it just the definition of the tangent.
Top one is 56
-9 + <u>112 </u>= 7(x2 - 8x + <u>16 </u>)
1) consistent system. at least one solution.
2) inconsistent system. no solutions (the lines are parallel)
3) dependent system. equations have same slope and y-intercept(same line)independent system.
4) equations have different slopes(2 intersecting lines)
im not sure if thats what you were looking for
What do you need help on??
