Functions have one output for every input. So that means one x-coordinate for one y-coordinate. In this case, (3,4) and (3,12) have the same x-coordinate, so it can't be a function.
Answer:
equation~ 2x + 5= 2X + 8
Value of X~ 0.3
Perimeter:13
Step-by-step explanation:
equation: 2x + 5 =2x +8
2x + 5= 2x+ 8
4x + 5= 8
4X= 13
x= 0.3
value of X: 0.3
Perimeter: 13
Is there more to the question,
Answer:
undefined
Explanation: none
Answer:
x=8
Step-by-step explanation:
2.25x=1.5x+6
-1.5x -1.5x
0.75x=6
3/4x=6
x=6*4/3
x=24/3
x=8
