plug each point into the inequality if you get a true inequality, then that point is in the solution set

  • jim_thompson5910
for example, let's check choice A y≥4x - 5 4≥4*3 - 5 4≥12 - 5 4≥7 which is FALSE, so (3, 4) is NOT a solution So choice A is out

well good luck I am pretty sure that the teacher will want the line thing I'm not sure it depends on what was taught but the answers will be D

I don't tell the answers I just check to know if her work is right I have a degree but I have done this in years.

The answer should be D because \[1\ge4(1)-5\]
anonymous
  • anonymous
are you sure you got C
anonymous
  • anonymous
she got C
anonymous
  • anonymous
when you use c you get \[0\ge4(3)-5\] \[0\ge7\] Which isn't true so I am pretty positive it is D

A. (3, 4) B. (2, 1) C. (3, 0) D. (1, 1)

How many solutions does the system have? x = -4y + 4 2x + 8y = 8 A. one solution B. two solutions C. infinitely many solutions D. no solution
anonymous
  • anonymous
it should be infinitely many because if you put them into slope intercept form they are the same line
anonymous
  • anonymous
so c
anonymous
  • anonymous
Yes

The local zoo has two water tanks for the elephant exhibit that are leaking One water tank contains 12 gal of water and is leaking at a constant rate of 3 gal/h. The second water tank contains 8 gal of water and is leaking at a constant rate of 5 gal/h. When will the two tanks have the same amount of water? Explain. Let x = the number of hours the tanks are filling and let y = the number of gallons in the tank. A. In 2 hours, because the solution to the system is (2,18). B. They will never have the same amount of water because the solution to the system is (–2,18). It is not possible to have time be –2 hours. C. In –2 hours, because the solution to the system is (–2,18). D. They will never have the same amount of water because the solution to the system is (–2,18). It is not possible to have –2 gallons in the tanks.
