Answer:
29. (5,0) and (-7/2,0)
30. (-1,0) and (5/7,0)
Step-by-step explanation:
29. y=2x² - 3x - 35
y = (x-5)(2x+7)
y is 0 at x = 5 and -(7/2)
31: y=-7x² - 2x + 5
y = -(x+1)(7x-5)
y is 0 at -1 and 5/7
See the attached graph.
80.1 years, im not 100% sure of my answer though
Because weight = mass x surface gravity, multiplying your weight on Earth by the numbers above will give you your weight on the surface of each planet. If you weigh 150 pounds (68 kg.) on Earth, you would weigh 351 lbs. (159 kg.) on Jupiter, 57 lbs. (26 kg.) on Mars and a mere 9 lbs. (4 kg.)
Answer: Step-by-step explanation:
25y + 150x = 250 (÷25)
y+6x=10
y=10-6x
example x=1 y=4
A. 2/5 B. 1/3 just like the other person said lol
