Answer:area = x^2 +15x +36
Step-by-step explanation:
f(x)=40
x=8
so if x=2 it would be 40/8 which is 5
The discriminant of y=ax^2+bx+c is b^2-4ac
given
9x^2+10x+0
a=9
b=10
c=0
discriminant=10^2-4(9)(0)=100-0=100
the discriminant is 100
You can solve this by algebraically as well as graphically. When I tried both ways I got:
solution is x= -2<span />
The correct answer to determine the change in he account is by:
C. Subtracting last Monday's account balance from this Monday's account balance to find that the change in the balance is -$24.10.
Hope This helped :)
