Answer:

x = 2

Step-by-step explanation:

Rewrite the equation as 4x - 6 = 2

Move all terms not containing x to the right side of the equation:

Add 6 to both sides of the equation.

4x = 2 + 6

Add 2 and 6.

4x = 8

Divide each term by 4 and simplify.

Divide each term in 4x = 8 by 4.

$\frac{4x}{4} =\frac{8}{4}$

Reduce the expression by cancelling the common factors.

$x=\frac{8}{4}$

Divide 8 by 4.

x = 2

Answer:

x4−5x3−6x2+26x+20

Step-by-step explanation:

(x−5)(x3−6x−4)

=(x+−5)(x3+−6x+−4)

=(x)(x3)+(x)(−6x)+(x)(−4)+(−5)(x3)+(−5)(−6x)+(−5)(−4)

=x4−6x2−4x−5x3+30x+20

=x4−5x3−6x2+26x+20

NEED HELP ASP

Nostrana [21]

<h3>Answer: B) $878.28</h3>

================================================

Explanation:

She starts off $16.75 in debt

Later on she deposits $16.75 to get completely out of debt and make the balance 0. This is after depositing the $5.72

So far her balance is $5.72

Add on $872.56 to get 5.72+872.56 = 878.28

-------------

This is what your steps may look like

-16.75 + (5.72 + 16.75)

-16.75 + (16.75 + 5.72)

(-16.75+16.75) + 5.72

(0) + 5.72

5.72

5.72+872.56

878.28

PLZZZZ HELP What is the slope of a line that is perpendicular to a line whose equation is 3y=−4x+2 ?

earnstyle [38]

$\bf 3y=-4x+2\implies y=\cfrac{-4x+2}{3} \\\\\\ y=\stackrel{\stackrel{slope}{\downarrow }}{-\cfrac{4}{3}}x+\cfrac{2}{3}\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}$

so the slope of that line above is really -4/3, now

$\bf \stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}} {\stackrel{slope}{-\cfrac{4}{3}}\qquad \qquad \qquad \stackrel{reciprocal}{-\cfrac{3}{4}}\qquad \stackrel{negative~reciprocal}{+\cfrac{3}{4}\implies \blacktriangleright \cfrac{3}{4} \blacktriangleleft}}$
