I would GREATLY appreciate it if you could help me. (WORTH 20+ POINTS.) Joan went on a 3 day road trip to visit her best friend in North Carolina; she drove a total of 320.7 miles on the trip. The first day Joan drove 118.75 miles, on day two she drove 95.4 miles. How many miles must she have driven on the third day?

Part B: If Joan wanted to take a more scenic route home, her new total mileage would be 385.5 How many more miles is her trip home than her trip to North Carolina?

A: She drove 106.55 miles on the third day

B: 64.8 miles

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

168

step-by-step explanation:

i am pretty sure that the answer is 168
