Answer:
B. -8
Step-by-step explanation:
x-3y=136
18x+3y=-288
add the equations
19x=-152
divide by 19
x=-8
First off, plot the vertices. When you finish, you should get the shape of a kite, to prove that it is a kite, find the slope of the line between (1,1) and (5,5), then find the slope of (6,2) and (3,6), if one of the slopes are the reciprocal and negative of the other slope, then the 2 lines are perpendicular to each other. Then, use the distant formula to find the distand between (6,2) - (5,5) and between (3,6) - (5,5). If the two lines are congruent, then you have proven that the shape is indeed a kite. Then, use the distant formula to find the necessary lines and use the kite are formula.
Using the data, we can calculate the price per bottle for Brand A, which is:
24 / 2
= $12 per bottle
We also know that the slope of a line shows the rate of change, so the price per bottle for Brand B is $15.
The difference per bottle is 15 - 12 = Brand B is cost $3 more per bottle
The difference for 9 bottles will be: 9 * 3 = $27.
17 miles / 5 mph = 3.4 hours
22miles / 7 mph = 3.14 hours
No would arrive before yes
