Answer:
Step-by-step explanation:
10x - 2 - 6x = 2(2x - 1) <em>use the distributive property </em><em>a(b + c) = ab + ac</em>
(10x - 6x) - 2 = (2)(2x) + (2)(-1)
4x - 2 = 4x - 2 <em>subtract 4x from both sides</em>
-2 = -2 TRUE
<em>Conclusion: It's the Identity Equation (x ∈ R). </em>
1/4
0.3
because there are only one decimal place
f=4-3t^2/t+1
