Answer:
4x -51
Step-by-step explanation:
m(n(x)) = m(x - 10) = 4(x-10) - 11 = 4x -40 -11 = 4x -51
<span>t – (–16.5) = –13.4
t + 16.5 = -13.4
t = (-13.4) + (-16.5)
t = -29.9
Anser is A. t = -29.9</span>
Answer:

Step-by-step explanation:
Answer:
The value of b = 1/36
As exponent decreases, each previous value is divided by 6
If the table was extended, the value of 6^-3 would be 1/216
Step-by-step explanation:
Given in the question a table containing power of 6
We will use negative rule of exponent to write the equivalent of negative power of 6
b^{-n}= 1 / b^{n}
we know that

so
= 1/6
and

So,

=

Answer:
Step-by-step explanation:
Water in a 10 gallon tank is draining at a rate of 2 gallons per hour.
= 10 - 2x
Water in a separate tank is filling at a rate of 4 gallons per hour.
= 10 + 4x
Equating both Equations together
10 - 2x = 10 + 4x
10 - 10 = 4x - 2x
How long until the tanks have the same amount of water?
Let the time = x
