Solve the inequality 12(1/2x-1/3)>8-2x
Setler [38]

Answer:

The answer is

<h2>x >  \frac{3}{2}</h2>

Step-by-step explanation:

<h3>12( \frac{1}{2} x -  \frac{1}{3} ) > 8 - 2x</h3>

<u>Expand the terms in the bracket</u>

That's

<h3>6x - 4 > 8 - 2x</h3>

Move - 2x to the left side of the inequality to make it positive

<h3>6x + 2x - 4 > 8 \\ 8x - 4 > 8</h3>

<u>Add 4 to both sides</u>

That's

<h3>8x - 4 + 4 > 8 + 4 \\ 8x > 12</h3>

<u>Divide both sides by 8</u>

<h3>\frac{8x}{8}  >  \frac{12}{8}</h3>

We have the final answer as

<h3>x >  \frac{3}{2}</h3>

Hope this helps you

Answer:

Axis of symmetry: x = 0.5; Vertex: (0.5, –0.75); f(x) = –x2 + x – 1

Step-by-step explanation:

The answer is A because the axis of symmetry is in between 0 and 1, the vertex lies on 0.5 and -0.75, and the parabola opens down so the coefficient of a is -1, and the y-int or the value of c is -1

The vertex of the function is  axis of symmetry is  and the formula for the function is  Option (a) is correct.

Further Explanation:

Given:

Calculation:

The standard form of the parabola is shown below.

Here, the parabola has vertex at  and has the symmetry parallel to x-axis and it opens left.

The general form of the parabola can be expressed as follows,

The graph is a downward parabola.

From the graph it has been observed that the vertex of the parabola is

Symmetry of the graph is  

The -intercepts of the graph is  Therefore, the value of is  

The value of  is -1 as the graph is a downward parabola.

The vertex of the function is  axis of symmetry is  and the formula for the function is  Option (a) is correct.
