Step-by-step explanation:
Just took the test.
Answer: Choice B
======================================================
Explanation:
The original equation is 
with 8 as the base. That is also the base of the log when we get the final answer shown above. Logs are useful to isolate the exponent.
The general rule is that 
is equivalent to the log form of 
where b is the base of each.
Answer:
45
Step-by-step explanation:
Answer:
y=4/5-2
Step-by-step explanation:
m=slope
m=4/5
(x,y)
(-5,-2)
y=mx+b
y=4/5-2
Multiply both sides by 5 to go from this
x/5 >= -2
to this
x >= -10
The notation ">=" without quotes means "greater than or equal to"
To graph this, plot -10 on the number line as a closed circle. Shade to the right of this closed circle. The shaded region represents all the solutions to the original inequality.
Final Answer: Choice D
