SOLUTION: Solve the equation x(x-3) = 40 - Algebra Homework Help
x^2-3X-40=0 Find possible factors for 40 (40,1) (2,20) (8,5) We see that the 40 has a negative sign which means that one of the factors is negative. Then we find which two factors when added together can give you -3 I can see from the list that the only possible answer is 5,8 (x-8)(x+5)=0 is the factored form of the above equation Therefore the ...

SOLUTION: solve the sytem algebraically y^2 = x^2 - 32 x^2
Substitute x^2-32 in for y^2 in the second equation. x=-6 or x=6 Let x=-6 or x=6 (They will both have the same outcome because x is squared.) in the first equation and solve for y.
SOLUTION: Tory and Emilio's motorboats travel at the same …
Tory pilots her boat 40 km before docking. Emilio continues for another 2 hr, traveling a total of 100 km before docking. How long did it take Tory to navigate the 40 km? Let their speeds = x km/h time taken by tory = 40/x hours to dock Emilio pilots for another 2 hours = (40/x)+2) hours Emilio pilots 100 km for (40/x)+2) hours d/t=r

SOLUTION: The profit function for a computer company is given …
The profit function for a computer company is given by P(x) = -x^2+ 25x - 24 where x is the number of units produced (in thousands) and the profit is in thousand of dollars. a) Determine how many (thousands of) units must be produced to yield maximum profit. Determine the maximum profit.---Maximum profit occurs when x = -b/2a = -25/(2*-1) = 12.5
SOLUTION: The cost C (in dollars) for a company to produce and …
h = -(-2)/(2*(1/30)) h = 2/(2/30) h = (2/1) / (2/30) h = (2/1) * (30/2) h = (2*30)/(1*2) h = 60/2 h = 30 The x coordinate of the vertex is 30. The y coordinate of the vertex is k, which is defined as k = f(h) For this problem, k = f(30) In other words, we plug in x = 30 to find the y coordinate of the vertex. Replace every x with 30; use PEMDAS ...
