Answer:  " 4x + 2xy - 7pq " .
___________________________________
Explanation:
___________________________________
Given:  
" <span>4x - 7xy + 9xy - 7pq " ;  Simplify the expression;
___________________________________
  Combine the "like terms:
___________________________________
       -7xy + 9xy = 2xy ;
___________________________________
Now, rerewrite the expression, substituting the "-7xy + 9xy";  with " + 2xy" ;

Napolean went on a bus trip, traveling at a speed of 55 miles per hour for 4 hours. Which equation will help you find the distan
mr_godi [17]
Well we have the equation d = r * t 
(d stands for distance, r for rate, and t for time)

So, plug in our values:

d = 55 *4

And, d = 220

I can't see the answer choices, but I hope this will help you!! Let me know if you have ANY questions.

Answer: x = 1/16

Step-by-step explanation:

Since the inverse of a Logarithm is an exponential function, we know that the final solution has to involve an exponential function somewhere in it.

1. log B(2) {x} = -4  || given

2. x = 2 ^ -4  || Logarithm rule that allows you to move the base of the logarithm to the base of the exponent on the other side. For example, if you had log B(5) {x} = 3, the base of 5 would move over to the other side and it would be raised to 3; x = 5^3.

3. x = (1) / (2^4) || Simplify. Use the negative exponent rule. This rule always leaves a numerator of 1, and a denominator of your exponent. In this case, it will be 2 ^ -4, so you will do 2^4 which is 16 and you will put that over 1. Resulting in your final answer of x = 1/16
