Solving for X it would be
X=-4-2y
Solving for Y it would be
Y=-2-x/2
4x+(3x-8)=90
4x+3x-8=90
7x=98
x=98/7
x=14
If x=14,
angle CDJ is:
(3(14)-8) degrees
=34 degrees
Well it really depends what u r solving for. So for perimeter u could add both X’s so 2x, and then add 10+2 which is 12. So it would be 2x+12. Not 100% right but I tried hope this helps and good luck!
The graph of proportional relationship is the straight line in Quadrant I and start in the origin.
Look at the picture.
