Answer:
8x² - 14x - 15
Step-by-step explanation:
(4x + 3)(2x - 5)
8x² - 20x + 6x - 15
8x² - 14x - 15
The graph of <span>y=-0.5 sqrt (x-3)+2
Df= {x/x-3>=0}
Df= [3, + infinity[
derivative of f(x)
f'(x)= -0.5 x 2 /</span>sqrt (x-3)= - 1/sqrt (x-3) <0, f is a decreasing function for all x in the Df
limf(x)=2 x--------->3, limf(x)=-infinity, x--------->+infinity
look at the graph
Answer: He planted 670 acres of corn.
Step-by-step explanation:
Let x be the number of acres of corn and y be the number of acres wheat Farmer planted.
According to the given information, we have the following system of equations:
Divide equation (2) by 135 , we get
Subtract eqn (1) from (3), we get
Put value of x in (1), we get
Hence, he planted 670 acres of corn.
