I think it would be C since two right angles both have a total of 90 degrees. So if u were to add the two angels u would get 180
X=-2y
1. ( , 0);
2. (9, );
3. ( , -2);
1. (0, 0), as any number multiplied by 0 is 0.
2. x=9, so 9=-2y, y=-4.5 - (9, -4.5)
3. y=-2, so -2y=(-2)*(-2)=4=x - (4, -2)
Solutions: (0, 0), (9, -4.5), <span>(4, -2).</span>
Answer:
x=8
Step-by-step explanation:
subtract 9 from 17 to get x alone on one side. 17-9=x+9-9. That will equal 8=x. Hope this helps
