If the discriminat of a quadratic equation is 4 which statement describes the roots

Alex Ar [27]

Answer: using the discriminant to find the number of solutions to a quadratic equation b^2-4ac. positive discriminant indicates that the quadratic has <u>two distinct real number solutions.</u> The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Perform the following division. Be sure answers are reduced to lowest terms. 2 7/8 ÷ 1/4 =

sergejj [24]

The answer is: [D]: 11 1/2 .
___________________________________________________________
Explanation:
___________________________________________________________
2 7/8 <span>÷ 1/4 =

23/8 </span>÷ 1/4 = 23/8 * 4/1 ; The "4" cancels to a "1"; and the "8"
cancels to a "2"; (since "8÷4 =2" ;
and "4÷4 = 1" ;
__________________________________________________________
→ 23/8 * 4/1 = 23/2 * 1/1 = 23/2 * 1 = 23/2 = 11 1/2 ;
__________________________________________________________
→ which is: Answer choice: [D].

What is the equation for the line of reflection? On a coordinate plane, triangle A B C has points (6, 3.7), (5.4, 2), (1, 3). Tr

elixir [45]

Answer:

The equation for the line of reflection will be x = y.

Step-by-step explanation:

On a coordinate plane, triangle Δ ABC has points (6, 3.7), (5.4, 2), (1, 3). Triangle Δ A'B'C' has points (3.7, 6), (2, 5.4), (3, 1).

And we have to find the equation of the line of reflection of the points.

Now, it is clear from the coordinates of vertices of Δ ABC and Δ A'B'C' that after reflection the x and y-values of the respective coordinates interchange and there is no change in signs.

Therefore, the equation for the line of reflection will be x = y. (Answer)
