Answer:
B = 100
Step-by-step explanation:
25 + .05x = 20 + .10x
5 = .05x
100 = x
Answer:
Step-by-step explanation:
plot five points of f(x)=(1/2)^x
f(0)=(1/2)^0=1
f(1)=(1/2)^1=1/2... through five gives you
y=1, 1/2, 1/4, 1/8, 1/16 for points
(0, 1),(1, 0.5),(2, 0.25),(3, 0.125),(4, 0.0625)
The left hand side of the equation is a difference of two squares and may be factored out as follows,
(x - 4)(x + 4) > 0
They may be individually taken as,
x - 4 > 0 ; x > 4
x + 4 > 0 ; x < -4
Thus, the answer to this item is letter A.
Three hundred nine thousand and seventeen
