The answer for that problem is X<26
The ratio is 0.394 cm. / 1 in.
Two equations with infinite solutions would look the exact same. Example:
y=mx+b
y=mx+b
Example 2
y=2x+5
y=2x+5
For an equation with no solution they would have the same slope but different y intercepts. An equation with same slope and same y intercepts would have infinite solutions.
1. x(2x^2-x+4)
2.-3(y-1)(y+2)
3.-(11w^2+18w-1)
