Answer:
False
Step-by-step explanation:
Here's a simple little trick to tell wether a system of inequalities has any solutions or not, just by looking at it:
- If the slopes are the same but the y-intercepts are different, the system has no solutions.
- If the slopes are different, the system has only one solution.
- If the slopes are the same and the y-intercepts are the same, then the system has infinitely many solutions.
By following this logic, since the system given has different slopes, it only has one solution. Therefore your answer is false.
Hope this helps you.
Answer:
Step-by-step explanation:
3kx + 24 = 9kx
First subtract 3kx to both sides.
24 = 9kx - 3kx
24 = 6kx
Divide both sides by 6
24/6 = kx
4 = kx
Divide both sides by k.
4/k = x
B because you are looking for an equation in the problem so if it starts at 16 and you are adding 2 gallons per hour you get 16+2x. Then for the other tank you start with 20 gallons and you are loosing 3 gallons per hour so you get 20-3x. To solve the equation you make them = each other so then you have 16+2x=20-3x.
