How to solve <br> 2(-3x + 4) = 5x + 2
ryzh [129]

Answer:

x = 6/11

Step-by-step explanation:

2(-3x + 4 ) = 5x + 2  

    -6x + 8 = 5x + 2      

           - 2          - 2

    -6x + 6 = 5x

   +6x         +6x

             6 = 11x

            /11   /11

           6/11 = x

10=c+d<br> c is one more than d <br> what is the value of c?<br>with working out
Leya [2.2K]
C= 5.5 I'm pretty sure that's the answer

d= 4.5 and c+ 5.5
Because 4.5 plus 1.0 = 5.5
since c is one more than d

5.5 plus 4.5 = 10

A company produces x units of a product per month, where c(x) represents the total cost and r(x) represents the total revenue fo
Nat2105 [25]

Answer:

The total profit P(x) or the month is P(x)=-0.5x^2+500x-350.

Step-by-step explanation:

A company produces x units of a product per month.

The total cost represents by the function C(x).

C(x)=300x+250

The total revenue represents by the function R(x).

R(x)=-0.5x^2+800x-100

The profit is the difference between revenue and cost.

P(x)=R(x)-C(x)

P(x)=-0.5x^2+800x-100-(300x+250)

P(x)=-0.5x^2+800x-100-300x-250

Combine like terms.

P(x)=-0.5x^2+(800x-300x)+(-100-250)

P(x)=-0.5x^2+500x-350

Therefore, the total profit P(x) or the month is P(x)=-0.5x^2+500x-350.
