1/4(20-4a)=6-a (distribute 1/4)
5-a=6-a (subtract 5 to both sides)
-a=1-a (add "a" to both sides)
0=1
When this happens where the equation is not true, it means that a=no solution because there would be no "a" value that you could plug in to make the equation true.
Answer:
1:2:3
Step-by-step explanation:
the number changes by the degree so you need to multiply it.
B. Domain is left to right so the left point is solid on 2 and the right is solid on 8. The solid point means it can also be equal to.
