2. A sailboat with a sick passenger abroad is following a parabolic path given by y = -x + 2x + 8. The boat's captain sent out a distress signal. A speedboat is trying to catch the sailboat to
provide medical aid and is on a path given by the linear equation y = -x + 8. Besides the y-intercept (starting
location) where do the paths of the two boats cross (show all the appropriate work and give answer in
coordinate pair notation)?

The sailboat and speedboat meet at x=3.

Step-by-step explanation:

Assuming your first equation is (you missed the square).

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
