Jane final solution is wrong due to the direction of the inequality sign
<h3>Solving linear equation</h3>
Linear equations are equation that has a leading degree of 1
Given the inequality below
-8x + 12x + 2 ≥ 62
Simplify to have
4x + 2 ≥ 62
Subtract 2 from both sides
4x + 2 - 2≥ 62 - 2
4x ≥ 60
Divide both sides by 4
4x/4≥ 60/4
x≥ 15
We can see that jane final solution is wrong due to the direction of the inequality sign

Answer:
<em>Correct answer: C. (1,∞)</em>
Step-by-step explanation:
<u>First Derivative</u>
Given a real continuous function f(x), the first derivative f'(x) represents the slope of the tangent line for any value of x.
If the slope of the line is positive, then the function is increasing, if the slope of the line is negative, the function is decreasing.
The function to analyze is:
![f(x)=x^2-2x+1](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2-2x%2B1)
Computing the first derivative:
![f'(x)=2x-2](https://tex.z-dn.net/?f=f%27%28x%29%3D2x-2)
The function will be increasing when:
![2x-2>0](https://tex.z-dn.net/?f=2x-2%3E0)
Dividing by 2:
![x-1>0](https://tex.z-dn.net/?f=x-1%3E0)
Solving:
x > 1
This solution is represented by the interval (1,∞)
Correct answer: C. (1,∞)
Answer:
Below in bold.
Step-by-step explanation:
|-7-9x|=2
The left side is the absolute value of -7 - 9x, therefore
-7 - 9x = 2 or -7-9x = -2
-9x = 2 + 7
-9x = 9
x = -1
OR
-9x = -2 + 7
-9x = 5
x = -5/9.
Simple...
the vertex of the graph of
![2 x^{2} -3](https://tex.z-dn.net/?f=2%20x%5E%7B2%7D%20-3)
is-->>>
Vertex:(0,-3)
Thus, your answer.
