Answer:



Step-by-step explanation:
We want to select all the terms that are not considered to be like terms with
.
The terms that are like terms with
must have
.
It doesn't matter the coefficient.
So we can easily see that all the following are not like terms with
:



Answer:
It is choice 3
Step-by-step explanation:
The answer is: 
By definition, a point is a local minimum if it has the smallest <em>y</em> coordinate in that interval and the graph goes from decreasing to increasing.
Based on this information, you can graph the points given in the problem above, as you can see in the figure attached. Then, you can notice that the ordered pair that is closest to a local minimum of the function is the last option shown in the problem.
<u>Answer</u>
20%
<u>Explanation</u>
let the cost of tie = x
Then cost of a pair of pants = (100+50)%x
= 150%x
= 1.5x
The cost of shirt = (100+25)%x
= 125%x
= 1.25x
(1.5x - 1.25x)/1.25x × 100
0.25x/1.25x × 100
0.2 × 100 = 20%
