Answer:

A

Step-by-step explanation:

12x² - 7y² - 10x² + y² = 12x² - 10x² - 7y² + y²

                                 = (12 - 10)x² + (-7 + 1)y²

                                  = 2x² + (-6y²)

                                  = 2x² - 6y²

Jaxon is traveling from Portland, Oregon to Denver, CO. If he were traveling by car, he would drive 1000 miles east and 575 mile
nordsb [41]

Answer:

1153.5 miles (first answer choice)

Step-by-step explanation:

'1000 miles east' is the change in x ('the run'), and '575 miles south' is the change in x (the 'rise').  Since these two vectors form a right angle, we can immediately apply the Pythagorean Theorem without worrying about signs:

d = √(1000² + 575²) = 1153.5 miles (first answer choice)
