Sean [tex]f(x) = 5\cdot x -14[/tex], [tex]g(x) = 12\cdot x + 8[/tex] y [tex]h(x) = 62\cdot x - 54[/tex]. A continuación, desarrollamos las siguientes operaciones:

a) [tex]f(x) + g(x)[/tex]

[tex](5\cdot x - 14) + (12\cdot x + 8)[/tex]

[tex]17\cdot x -6[/tex]

b) [tex]g(x) - [h(x)-f(x)][/tex]

[tex](12\cdot x + 8) - [(62\cdot x - 54)-(5\cdot x - 14)][/tex]

[tex]12\cdot x + 8 - (57\cdot x -40)[/tex]

[tex]12\cdot x +8 -57\cdot x +40[/tex]

[tex]-45\cdot x +48[/tex]

c) [tex][g(x)-f(x)]\cdot [h(x)+g(x)][/tex]

[tex][(12\cdot x + 8)-(5\cdot x -14)]\cdot [(62\cdot x -54)+(12\cdot x +8)][/tex]

[tex](7\cdot x +22)\cdot (74\cdot x-46)[/tex]

[tex]7\cdot x \cdot (74\cdot x - 46)+22\cdot (74\cdot x -46)[/tex]

[tex](7\cdot x)\cdot (74\cdot x) - 46\cdot (7\cdot x )+22\cdot (74\cdot x)-22\cdot (46)[/tex]

Answer:

[tex]Rate = -5[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 2x^2 - x - 4[/tex]

[tex]-4 \le x \le 2[/tex]

Required

Determine the average slope over the given interval

This is calculated as:

[tex]Rate= \frac{f(b) - f(a)}{b - a}[/tex]

Where:

[tex]a = -4[/tex]

[tex]b =2[/tex]

So:

[tex]Rate= \frac{f(2) - f(-4)}{2 - (-4)}[/tex]

[tex]Rate= \frac{f(2) - f(-4)}{2 +4}[/tex]

[tex]Rate= \frac{f(2) - f(-4)}{6}[/tex]

Solving for f(2) and f(-4), we have:

[tex]f(x) = 2x^2 - x - 4[/tex]

[tex]f(2) = 2 *2^2 -2 - 4[/tex]

[tex]f(2) = 2[/tex]

[tex]f(-4) = 2*(-4)^2 - (-4) - 4[/tex]

[tex]f(-4) = 2*16 +4 - 4[/tex]

[tex]f(-4) = 32[/tex]

So, the equation becomes

[tex]Rate= \frac{f(2) - f(-4)}{6}[/tex]

[tex]Rate= \frac{2 - 32}{6}[/tex]

[tex]Rate= \frac{-30}{6}[/tex]

[tex]Rate = -5[/tex]

I also recommend Desmos because it helps you with these questions.

and that's what I used.

The inequality represented by the graph below is y > 2x - 3.

Option B is the correct answer.

An inequality is a mathematical statement that compares two expressions using an inequality symbol such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).

We have,

To graph an inequality, you need to identify the equation of the line or boundary that separates the two regions defined by the inequality.

This boundary can be a line, a curve, or even a plane in three dimensions.

Next, you need to determine which region to shade, based on whether the inequality symbol is less than (<), greater than (>), less than or equal to (≤), or greater than or equal to (≥).

If the inequality symbol is less than (<) or greater than (>), the boundary line should be drawn as a dashed line since the points on the line are not included in the solution set.

Then, shade the region above the line if the symbol is greater than (>), or below the line if the symbol is less than (<).

If the inequality symbol is less than or equal to (≤) or greater than or equal to (≥), the boundary line should be drawn as a solid line since the points on the line are included in the solution set.

Then, shade the region above the line if the symbol is greater than or equal to (≥), or below the line if the symbol is less than or equal to (≤).

Finally, label the shaded region as the solution set and write the inequality symbol next to it.

From the given graph we see that,

y > 2x - 3 has the same graph.

Thus,

The inequality represented by the graph below is y > 2x - 3.
