Answer

Explanation

The quadratic equation to be solved is

x² + 4x - 4 = 0

The graph of this equation is plotted and attached under 'Answer'.

From the graph, we can see that the solutions of the equation include

x = -4.828 and x = 0.828

The equation has two roots, that is two solutions.

Hope this Helps!!!

Let D = {x| x is a student} be the domain, and let ƒ(x) = “date of birth” be the possible function. Determine if the relation is
Kazeer [188]

It is.

The function is just another way of saying to transfer something from domain A to domain B.

f(x)=y:A\longrightarrow B; x\in A, y\in B

Now your function states:

D=\{x\} \\f(x)=y: D\longrightarrow E; x\in D, y\in E

In the diagram below, lines a and b are parallel and cut by transversal, t. If angle 3 is 120 degrees, find the measure of angle
Vlad1618 [11]

Lines a and b are parallel and cut by the same transversal, t. Since we know these lines are parallel, we can find the measure of angle 7 quite easily.

Angles 3 and 7 are corresponding angles, which means that the two angles are in the same relative position. Thus, they are equivalent.

Angle 3 = angle 7 = 120 degrees

The correct answer is C. 120.

Hope this helps!! :)
