D is the answer
40050 divided by 3.14 is 12754.77707
2x-y-1=0
There are 2 ways that you can solve this . Either plug in the x and y value into each equation until it is right or rewrite the equation .
the equation in slope intercept form is y=2x-1
When you get y by itself in the last one it is also equal to y=2x-1
For both ways work is attached !
yikes i remember doing this but.... i completely forgot ;–; i really wish i could help
4/(6+89-34-89+190)
=4/162
