Which of the following is the solution set for the conjunction –6 < 4x + 2 < 6? x>−32 and x<32 x >–2 and x < 1

alisha [4.7K]

$-6$

<em><u>Solution:</u></em>

<em><u>Given conjunction is:</u></em>

$-6$

We have to find the solution set

<em><u>Let us solve the given conjuction</u></em>

$\mathrm{If}\:a$

Therefore,

$-6$

<h3><em><u>Let us first solve -6 < 4x + 2</u></em></h3>

$-6 < 4x + 2$

Switch the sides by flipping the inequality symbol

$4x+2>-6$

$\mathrm{Subtract\:}2\mathrm{\:from\:both\:sides}\\\\4x+2-2>-6-2\\\\\mathrm{Simplify}\\\\4x>-8\\\\\mathrm{Divide\:both\:sides\:by\:}4\\\\\frac{4x}{4}>\frac{-8}{4}$

$x>-2$

<h3><u><em>Now let us solve 4x + 2 < 6</em></u></h3>

$4x+2$

$\mathrm{Combine\:the\:intervals}$

$x>-2\quad \mathrm{and}\quad \:x$

$Merge\:Overlapping\:Intervals$

$-2$

<h3><u>Thus the solution set for –6 < 4x + 2 < 6 is:</u></h3>

$-6$

On the graph of the equation 8x – 3y = 24, what is the value of the y-intercept?

ella [17]

8x - 3y = 24

y-intercept ⇒ x = 0

subtitute

8 · 0 - 3y = 24

-3y = 24 |divide both sides by (-3)

y = -8

The original area of a face would be a^2. Now that you added b to the edge, the new area of each face would be (a+b)^2. To find how much the are increased, subtract a^2 from (a+b)^2. $(a+b)^2-(a^2)= a^2+2ab+b^2-(a^2)= 2ab+b^2= b(2a+b)$ So the answer is b(2a+b)
