Answer:
The quadratic equation has one real root with a multiplicity of 2.
Step-by-step explanation:
Given a quadratic equation:
You can find the Discriminant with this formula:
<em> </em>In this case you have the following quadratic equation:
Where:
Therefore, when you substitute these values into the formula, you get that the discriminant is this:
Since , the quadratic equation has one real root with a multiplicity of 2 .
If <span>y = –4x – 7, the x-intercept is found by setting y=0 and solving for x:
</span><span>0 = –4x – 7 => 4x = -7, or x = -7/4 The x-intercept is (-7/4, 0).
</span><span>The y-intercept is found by setting x = 0 and reading off the value of y:
y = –4x – 7 => y = 0 - 7, or y = -7. The y-intercept is (0, -7).</span>
<u>1/2(x-4) = 4</u>
Multiply each side of the equation by 2 : (x- 4) = 8
Add 4 to each side of the equation: <em>x = 12</em>
Answer:
A horizontal line that has a slope of 0
