Explanation: A, C, and D all have a number in the x value that is repeated therefore making them not functions.
Answer:
1.25 * N
Step-by-step explanation:
We have to increase N by 25%.
The first thing is to say how the percentage works in these cases, N would be our 100% and the increase would be 25% in this case, therefore, the initial value must be added (that is, N, 100%) and to that if add 25% of the initial value (that is, + 25% N).
Thus:
100% * N + 25% * N = N * (100% + 25%)
N * (125%) = 1.25 * N
So to increase N is 25% it would be 1.25 * N
Step-by-step explanation:
Given that,
- Length of the one portion of the board = x feet
- Length of the another portion = (7x – 9) feet
According to the question,
Total length = Sum of the length of the two pieces
Total length = {x + (7x – 9)} feet
Total length = {x + 7x – 9} feet
<u>Total length = (8x – 9) feet</u>
Therefore, the total length of the board as a simplified expression in x is (8x – 9) feet.
