Answer:
30 minutes
Step-by-step explanation:
It took 20 minutes to progress from 5 to 9 feet meaning it goes 1 foot every 5 minutes. 15 - 9 is 6 and 6 * 5 = 30 meaning in 30 minutes it will reach 15 feet.
Answer: F
Step-by-step explanation:
- This does not have infinitely many solutions (adding the equations, we get a fixed value of x)
- This has no solutions (the left hand sides are the same but the right hand sides have different values)
- This has one solution (the first equation givess a fixed value for x)
- This has no solutions (same reason as 2)
- This has one solution (same reason as 3, just the second equation instead of the first)
- This has infinitely many solutions (multiplying both sides of the top equation by -2 gives the bottom equation).
X=2+√42 , hope that is helpful .
Solve for y by simplifying both sides of the equation, then isolating the variable.
y = 2, 2/3
