Answer: They need 7 buses
Step-by-step explanation:
40 x 2 =80 560 divided by 80 =7
F(-2) = -8 + 20 - 12 = 0 so first choice is correct
x^3 + 5x^2 + 6x = x(x^2 + 5x + 6) = x(x + 3)(x + 2)
so second choice is incorrect and third choice is correct
when x = 2 f(x) = 8 + 20 + 12 = 40 so last choice is incorrect.
Answer:
Step-by-step explanation:
The zeroes of a function is where its graph intercepts the x axis:
in this case it happens in these points:
(-6;0) , (-4;0) , (0;0) , (2;0) , (4;0)
4,000
I know this because 2,000 • 2 = 4,000
Answer:
The answer is 210
Step-by-step explanation:
200+(20-4)-2x3
first you'd do 20-4= 16
then you'd do 2x3=6
next you'd 16-6=10
finally 200+10=210
