Answer:
- x = x+1
- 0 = x+1
- x+1 = x+1
Step-by-step explanation:
1. There will be no solution if the equation is a contradiction. Usually, it is something that can be reduced to 0 = 1.
If we choose to make our equation ...
x = x +1
Subtracting x from both sides of the equation gives ...
0 = 1
There is no value of the variable that will make this be true.
__
2. Something that reduces to x = c will have one solution. One such equation is ...
0 = x+1
x = -1 . . . . subtract 1 from both sides
__
3. Something that reduces to x = x will have an infinite number of solutions.
One such equation is ...
x+1 = x+1
Subtracting 1 from both sides gives ...
x = x . . . . true for all values of x
Answer:
The answer is B. 20 - 17 = 3
Step-by-step explanation:
( 3x + 5) - (2x + 7)...... x = 5
( 3(5) + 5) - ( 2(5) + 7)
( 15 + 5) - (10 + 17)
20 - 17 = 3
Thank you :)

Answer:
Hello,
I am not sure if you are still having an issue with this problem but for future reference for you or anyone else the answer is
d. Each vertical line drawn through the graph will intersect a function in only one location.
I thought of it this way:
"Each vertical line" which tells me only one line per "one location" now I could be completely off but this was just my logic and it helped me personally.
Answer:
Monday: 4 hours = $36
Tuesday: 6 hours = $54
Wednesday: 5 hours = $45
His earnings are proportional because, for each hour, Richard earns $9. Using the formula y = kx, k (the constant) is always the same:
- 36 = k × 4 (k = $9)
- 54 = k × 6 (k = $9)
- 45 = k × 5 (k = $9)
Hope this helps!
