What is the vertex of the graph of y= x ^2+4x

Mathematics

S_A_V [24]3 years ago
5 0
The vertex is (2,-4) because, if you do -b/2a you end up with 2 which is your x value, and then you would plug it in to get your y which is -4. 
Hope this helps, I am sorry if it did not. :))

Ab over 2 equal 2a minus 1,express a in terms of b
sasho [114]

\frac{ab}{2} = 2a - 1

2(\frac{ab}{2}) = 2(2a - 1) <em>multiplied both sides by 2 </em>

ab = 4a - 2 <em>distributed the 2 on the right side</em>

ab - 4a = -2 <em>subtracted 4a from both sides</em>

a(b - 4) = -2 factored out "a" from the left side

a = \frac{-2}{b - 4} <em>divided (b - 4) on both sides</em>

Answer: a = \frac{-2}{b - 4}
