Move all terms containing C to the left side of the equation. -8c-11=21

Move all terms not containing C to the right side of the equation. -8c=32

Divide each term by -8 and simplify.

32/8 equals -4

C=-4

-4c - 11 = 4c +21 add 4c to both sides

 -4c - 11 + 4c = 4c + 21 + 4c simplify

- 11 = 8c + 21 subtract 21 from both sides

- 11 - 21 = 8c + 21 - 21 simplify

- 32 = 8c divide both sides by 8

c = - 4

That's it

I hope you got the idea

A line passes through the point (10,5) and has a slope of 3/2. Write and equation in slope intercept form

ehidna [41]

$\bf \begin{array}{lllll}
&x_1&y_1\\
% (a,b)
&({{ 10}}\quad ,&{{ 5}})\quad 
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{3}{2}
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-5=\cfrac{3}{2}(x-10)\implies y-5=\cfrac{3}{2}x-15
\\\\\\
y=\cfrac{3}{2}x-15+5\implies y=\cfrac{3}{2}x-10$

Which algebraic expression is represented by the model?

DerKrebs [107]

Answer:

3(2x+2) = 6x + 6

Step-by-step explanation:

Those are algebra tiles, so it is saying (if you read across the top) 2x +2 then if you read down you have 3 units, so the dot means 2x + 2 multiplied by 3

If you write it in algebraic terms it is 3(2x+2) so the answer when you distribute is 3 (2x) + 3(2) so 6x + 6, and if you count the number of red rectangles you have 6 of them, hence the 6x, and if you cound the units in gray you have 6 of them, hence the 6.

Algebra tiles are used to demonstrate algebra concepts
