Ответ:
u+b=21
Manipulate that equation into something that looks like slope-intercept form.
u+b=21
u+b−b=21−b
u=21−b
Now just rearrange the terms on the right side. You have an answer. If you needed the other equation, it would be set up like
u+2b=30
SO the answer is 30
Ответ:
(3,0) and (0,6)
Step-by-step explanation:
(x,y) is the only way to make ordered pair.
The x was a 3 so you could cross out the first and last because they put the 3 in the y spot. When is should be (3,0).
Then the y was 6 and that I would be (0,6) so the third would also be crossed out because they put the 6 in the y spot.
So the answer is (3,0) and (0,6).
