Answer:
Step-by-step explanation:
<u>Given Equation is:</u>
Adding 9 to both sides
=>
=>
Multiplying 2 to both sides
=> -3x = -18 * 2
=> -3x = -36
Dividing both sides by -3
=> x = 12
Answer:
the first one on the bottom
Step-by-step explanation:
There is a little trick to find out if it is a function or not. This trick is called the vertical line test. if you can scan the figure with a virtual line and it does not touch more than one side of the figure at one time then it is a function. if it touches more than one side or line of the figure it is not a function.
1. Use the distributive property:
Then
2. Separate terms with m in left side and without m in right side:
This expression is false for all values of x, then the equation doesn't have solutions.
Answer: no solution
