Answer:
The first one is infinite and the second one is one solution
7x + 1 = x + 7
7(1) + 1 = 8
1 + 7 = 8
If you substitute 1 for x, the statement is true. Therefore, x = 1.
Answer:
The x-int.s are (2, 0) and (4, 0) so the midpoint will be (3, 0).
5+15=20
20x3=60
I'm probably wrong, but thats how I understood the question.
_
| x+y(less than or equal to)17
| 11x+8y(greater than or equal to)160
