2. a company calculates its profit by finding the difference between revenue and cost. the cost function of
producing x hammers is c(x) - 4x + 170. if each hammer is sold for $10, the revenue function for selling x
hammers is r(x) - 10x. how many hammers must be sold to make a profit? how many hammers must be sold to
make a profit of $100?

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

it is c, trust i got your back lol

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
