... question directly. The correct answer is C. 60. Since c > 0 and d > c , c and d must be positive. b could be negative or positive. Let's look at each answer choice: (A) UNCERTAIN: ... |0| = 0 pos - 0 = pos Is 0 < pos? Yes. pos pos pos · |pos| = more positive pos (far from 0) - pos (close to 0) = less positive Is more positive < less positive? No. Fo...

... equation and solve for x: So the two possible values of x are -4 and -5 . Therefore, the two points where the circle and line intersect (points B and C) have x-coordinates -4 and -5 , respectively. ... P as its center, we can see that the proportion of lines passing through P and ABCD will be the same as the proportion of the semicircle occupied by sector APB....

... We can use this to solve for r . CQ + QB = CB. Since CQ = 2/7QB and QB = r , we can construct the following equation: . Therefore, . AP + PB = AB. Since AP = 1/2PB and PB = r , we can construct ... Notice that the point A is HIGHER on the circle's perimeter than point X. This is because point A is directly above the center of the circle, it the highest point on the circle. Thu...
