Question: 3x-6y= -12
Answer: (solve x) x= -4+2y (solve y) y=2+1/2
Answer: When solving the system, if you get a false statement (a number equal to a different number) this means there are “no” solution.
Step-by-step explanation: Therefore, this means that if there is no applicable or possible solution, then there is “no“ solution. This also means that there‘s no way you can answer the equation.
B) 2 packs because 4 packs is $2.50 for each 3 packs is $2.17 for each pack and the 2 packs is $2 for each one
Answer:
-7, -8, -9, -10
Step-by-step explanation:
Is this actually the whole problem? If so, the answer is anything less than -6. z < -6 includes all the numbers less than -6, so that would include -7, -8, -1000, -6.000001, etc.; you get what I mean. This would NOT include -6, though, because z is less than, not equal to, -6.
You can visualize it on a number line. If every value that could possibly equal z had a dot on it, you would see an infinite number of dots starting from -6 and going left to infinity. Like: <-------------o, if o was -6.
