Answer:
For the first question, <u>the lines are perpendicular.</u> A line on the y-axis will always intersect with a line on the x-axis.
For the second question, <u>the lines are parallel</u>. The slopes are the same and if you change the equations to ordered pairs and put them on a graph, they will be parallel.

Answer:
45 miles
Step-by-step explanation:
Use the Pythagorean Theorem. Imagine a line connecting the ends of the right angle you made by driving. It would make a right triangle. You are trying to find the hypotenuse. Use the formula 
. Square 27, or multiply 27 by 27, to get 729. Add this to the square of 36, 1296. So 
= 2025. Find the square root of 2025. 
= 45. Hope this helped ^^
Answer:
$225.
Step-by-step explanation:
Let the price before taxes be x dollars. Then we have the equation:
x + 7% of x = 240.75
x + 0.07x = 240.75
1.07x = 240.75
x = 240.75/1.07
= $225.
