A manufacturing company calculates its profit margin using the following equation: Profit Margin = Net Income - Net Revenue. The company finds that its net income and net revenue can be described by the functions below F(t) = 8t? - 10t + 13, where t = time in months and F(t) = net income
• Rt 2t - 3, where t = time in months and R(t) = net revenue
Which expression describes the profit margin. F(t) = R(t)?
A
4t - 11+
46
B
4t+1+ 20
4t +1+ 2103
4t - 11 - 220

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
