X=2
So you solve for x by simplifying bath sides of the equation, then all you do is isolate the variables
answer: positive
for example: -2 x -2 x -2 x-2
=4 x -2 x -2
=-8 x -2
=positive 16
Answer:
Statistical significance
Step-by-step explanation:
The Statistical significance provides a link between the dependent and the independent variable. It provides us the indication that the change in the independent variable is correleated with the shift caused in the dependent variable.
Answer:
B.
Step-by-step explanation:
Well lets graph the following equation first,
H(x) = -.011(x - 82)^2 + 75
Then lets graph all the other equations.
Look at the image below↓
So A.
The purple line does not go farther or higher,
so A. is incorrect
B.
The black line goes higher and farther,
meaning it is correct.
C.
The red line goes farther but not higher.
So it is incorrect
D.
Again the blue line does not go farther of higher.
So its wrong.
<em>Thus,</em>
<em>answer choice B. </em> <em>is correct.</em>

<em>Hope this helps :)</em>
Answer:
<u>Option C. It is zero</u>
Step-by-step explanation:
The graph represents a quadratic equation
The quadratic equation has the form ⇒a x² + b x + c
The discriminant of the quadratic equation is D = b² - 4ac
From the discriminant of the quadratic equation, we can know the type of roots of the quadratic equation.
- If D > 0 ⇒ Two real roots.
- If D = 0 ⇒ one real roots
- If D < 0 ⇒ Two imaginary roots.
The roots of the quadratic equation are the x-intercepts of the function.
As shown at the figure, the quadratic equation has only one point of intersection with the x-axis
So, the function has only one root ⇒ D = 0
So, the discriminant of the quadratic equation = 0
<u>The answer is option C. It is zero</u>
