2x+4(7−x) HELP PLEASE IM DEPERATEEEEE

goldenfox [79]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{ - 2x + 28}}}}}$

Step-by-step explanation:

$\sf{2x + 4(7 - x)}$

Distribute 4 through the parentheses

$\dashrightarrow{ \sf{2x + 28 - 4x}}$

Collect like terms

$\dashrightarrow{ \sf{2x - 4x + 28}}$

$\dashrightarrow{ \sf{ - 2x + 28}}$

Hope I helped!

Best regards! :D

what is the algebraic equation product of 3 and a squared number is twice the sum of the number and 4

Katyanochek1 [597]

Let n = number

" product of 3 and a squared number" translates to 3n²

"sum of the number and 4" translates to n + 4

The word "is" becomes your equals sign.

3n² = n + 4 is your equation.

Find the solution set for the following problem. 5 diminished by 3 times a number is at most 11.

leva [86]

For this case, the first thing we are going to do is define the following variable:
x = unknown number
We now write the following inequality:
5-3x <= 11
We clear x:
5-11 <= 3x
-6 <= 3x
-6/3 <= x
-2 <= x
The solution set is:
[-2, inf)
Answer:
the solution set is:
[-2, inf)

The slope-intercept form of the equation of a line that passes through point (-3, 8) is y = -2/3x + 6. What is the point-

Elena-2011 [213]

$y = \stackrel{\stackrel{m}{\downarrow }}{-\cfrac{2}{3}}x+6\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}$

so hmmm then we know the slope of that line is -2/3, so we're really looking for the point-slope form of a line with a slope of -2/3 and that passes through (-3 , 8)

$(\stackrel{x_1}{-3}~,~\stackrel{y_1}{8})\hspace{10em} \stackrel{slope}{m} ~=~ -\cfrac{2}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{8}=\stackrel{m}{-\cfrac{2}{3}}(x-\stackrel{x_1}{(-3)})\implies y-8=-\cfrac{2}{3}(x+3)$
