Answer:

\boxed{x = -14}

Step-by-step explanation:

Solve  \: for  \: x:  \\  \implies  - x+8 + 3x=x - 6 \\  \\ Grouping  \: like \:  terms,  \:  - x + 8 + 3x = ( - x + 3x) +8  :  \\ \implies ( - x+3x)+8=x - 6  \\  \\ 3x - x=2x: \\ \implies \boxed{2x} +8=x - 6  \\  \\ Subtract \:  x \:  from \:  both \:  sides:   \\ \implies( 2x- \boxed{x})+8=(x- \boxed{x})-6  \\  \\ 2x - x = x:  \\ \implies \boxed{x}+8=(x-x)-6  \\  \\ x - x = 0:  \\   \implies x+8=-6  \\  \\ Subtract \:  8  \: from  \: both  \: sides:  \\ \implies x + (8 -  \boxed{8}) = -   \boxed{8} - 6 \\  \\ 8 - 8 = 0 : \\ \implies   x =  - 8 - 6 \\  \\  - 8 - 6 =  - 14 :  \\ \implies  x =  - 14

-2a-9=6a+15<br> Idk how to this equation could someone plzz consider helping me?
ollegr [7]

-2a-9=6a+15

Move 6a to the other side. Sign changs from +6a to -6a.

-2a-6a-9=6a-6a+15

-2a-6a-9=15

-8a-9=15

Move -9 to the other side. Sign changes from -9 to +9.

-8a-9+9=15+9

-8a=15+9

-8a=24

Divide both sides by -8

-8a/-8=24/-8

a=-3

Answer: a=-3

If fixed cost of 20 article is 500 and variable cost for each article is 40. Find the total cost function? Also ,find the total
Deffense [45]

Answer:

Cost function = 40a + 500

Cost of 90 articles = $4,100

Step-by-step explanation:

The fixed cost is $500 and it will.not change regardless of production level.

The Variable cost is $40 and increases by every additional unit produced.

Assume the number of articles produced is a.

Cost function would be:

Total cost = Variable cost * Number of articles + Fixed cost

TC = 40a + 500

Using this, the cost of 90 articles is:

= 40 * 90 + 500

= $4,100
