Preyton took longer so he was slower. Now, we calculate the average speeds of both:
Preyton: 150 / 3 = 50 mph
Bryson: 150 / 2.5. = 60 mph
Therefore, Bryson travelled 10 mph faster than Preyton
Answer: Infinitely Many Solutions
Step-by-step explanation:
Substitute y into the second equation:
2(-2x-6)=-4x-12
Then you get -4x-12=-4x=-12. Since this is 0=0 it would make it infinitely many solutions.
Answer:
6x^2 - 10x - 24
Step-by-step explanation:
- Do 3x times 2x which is 6x^2
- Do 3x times - 6 which is -18x
- Do 4 times 2x which is 8x
- Do 4 times - 6 which is - 24
- You get 6x^2 - 18x + 8x - 24
