Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0
Discriminant = 4 - 4(K)(-1) = 4 + 4K
For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.
The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.
Answer:
The point-slope form of this equation would be y + 3 = 1/2(x - 6)
Step-by-step explanation:
In order to find this, start with the base form of point-slope form.
y - y1 = m(x - x1)
Now input the slope for m and the point for (x1, y1)
y - -3 = 1/2(x - 6)
y + 3 = 1/2(x - 6)
The answer i thinkkk would be,
x < -1
Answer:
D
Step-by-step explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
here m = 2 and (a, b ) = (- 2, 1 ) , then
y - 1 = 2(x - (- 2)) , that is
y - 1 = 2(x + 2)
