Question

Can anybody help me with strategies in proofs?(Geometry)

Answer 1

heres one promblem,
-8v + 6v – 8 = -8v + 8v + 8 you have to find the justification

Answer 2

What's \(v\) here?

Answer 3

what do you mean?

Answer 4

What do we have to do in this problem?

Answer 5

your choosing if its Additive Inverse or Substitution Property or Given etc. Are you familiar with this?

Answer 6

3 + 7a = -9

3 + 7a = -9 Given.
-3 + 3 + 7a = -3 + -9 Addition Property of Equality
0 + 7a = -12 Substitution Property of Equality
7a = -12 Additive Identity
7 over 7 times a equals negative 12 over 7 Division Property of Equality
1 a equals negative 12 over 7 Substitution Property of Equality
a equals negative 12 over 7 Multiplicative Identity
these are some examples they gave me, but i dont understand.
