Answer:
x = 20
x = 140
Step-by-step explanation:
Find the equation for profit P
P = R - C
Substitute the equations for R and C then simplify.
P = 100x − 0.5x² - (20x + 700)
P = -0.5x² + 80x - 700
Find the values of x when profit is $700
P = -0.5x² + 80x - 700
700 = -0.5x² + 80x - 700
0 = -0.5x² + 80x - 1400
This is in the standard form 0 = ax² + bx + c
Use the quadratic formula to find values of x
(Ignore Â)
Substitute a b and c.
a = -0.5
b = 80
c = -1400
Split the formula at the ± so that there are two to get the two x values.
x = 20
x = 140
The profit will be $700 when x is 20 or when x is 140.
Answer:
8
Step-by-step explanation:
(4+8)+6 = (6+4)+n
18 = 10+n
18-10 = n
n = 8
Levant will receive about 9 american dollars when he exchanges his pesos.
According to this question, 1 american dollar is worth about 11 pesos. In order to find that, you need to divide 3000/270 which gives you around 11. In order to find out how many dollars he will receive for his pesos, you need to divide 100 by 11 which gives you about 9 dollars.
Answer:
Coordinates of other end point L = ( -19, 13 )
Explanation:
The mid point of the coordinates (a,b) and (c,d) is given by 
Here we have (a,b) = (1,-7) and = (-9,3) , we need to find (c,d).
So coordinates of other end point L = ( -19, 13 )
