Which system of any qualities has a line as a solution?

Mathematics

Answer:

Correct choice is A

Step-by-step explanation:

The line 2x+4y=3 divides the coordinate plane into two semiplanes (top and bottom).

The inequality 2x+4y\ge 3 represents the region of all points (x,y) (including line 2x+4y=3) which coordinates satisfy the inequality 2x+4y\ge 3.  Actually, this region is top semiplane (red region).

The inequality 2x+4y\le 3 represents the region of all points (x,y) (including line 2x+4y=3) which coordinates satisfy the inequality 2x+4y\le 3. This region is exactly bottom semiplane (blue region).

These two semiplanes intersect by line  2x+4y=3.

All another options contain some inequalities that do not include the line 2x+4y=3.

Which relations are functions?
guapka [62]

Answer:

The 1st and 2nd graph are functions while the 3rd and 4th aren't.

Step-by-step explanation:

The first and second graph doesn't have more than one output for each input. The third and fourth graph isn't a function since there's more than one output for the same input given. If you do the vertical line test, then you'll know which one is a function and which one is not a function. Hope this helps :)
