if x2 = 5 the value of x has to be 5 divided by 2 which is 2.5 x = 2.5
The vertex of this parabola is at -5 -2 When the x-value is -4 the y-value is 2. The coefficient of the squared expression in the parabola's equation is 4. y = a(x - h)2 + k; (h, k) = (-5, -2); (x, y) = (-4, 2) 2 = a[-4 -(-5)]2 - 2, add 2 to both sides 4 = a(-4 +5)2 4 = a(1)2 4 = a
well if your saying 2*-5 the answer is -10 but if your saying 2-5 then you would get -3
(2\5)
If you mean: 5x = 10 then the value of x is 2
